whsandchengyongru 5a401464a5 fix(agent): improve cross-channel session persist robustness 2026-04-16 15:04:00 +08:00
chengyongru 1747ed7885 fix(agent): persist cross-channel messages into target session history
When session A (e.g. websocket) uses the `message` tool to send to
channel B (e.g. feishu), the outbound message is delivered to the user
but was never recorded in session B's history. This caused session B to
lose context when the user replied on that channel.

Add `_persist_cross_channel_calls()` to detect cross-channel `message`
tool calls during `_save_turn()` and append a lightweight assistant
entry (with `_cross_channel: True` marker) to the target session.

# Design Constraints
These rules govern architectural decisions. When adding a feature or fixing a bug, prefer paths that respect these boundaries.
## Core stays small; extend at the edges
New capabilities should be added via `channels/`, `tools/`, skills, or MCP servers. The files `agent/loop.py` and `agent/runner.py` form the critical core path; changes there should be minimal and justified. If a feature can live in a channel adapter, a tool, or an external MCP server, it should not be inlined into the agent loop.
## Less structure, more intelligence
Prefer simple, readable code over new framework layers and indirection. Add structure only when it removes real complexity, protects an important boundary, or matches an established local pattern. The best fix is often a smaller prompt, a tighter tool contract, a channel-local change, or one focused regression test.
## Prefer duplication over premature abstraction
Channels and providers are allowed to repeat similar logic (send retries, media handling, message splitting). Do not introduce complex base classes or shared helpers just to eliminate duplication across channel files. Each channel file should remain self-contained and readable on its own. The same applies to provider implementations.
## Minimal change that solves the real problem
Fix bugs by changing only what is necessary. Do not bundle unrelated refactors or clean-ups into a feature or bugfix PR. If a refactor is genuinely required, it should be a separate PR targeting `nightly`.
## Keep PRs reviewable
A bugfix should make the protected invariant clear, change the smallest surface that enforces it, and add only the closest regression test. If a diff starts changing ownership boundaries or mixing behavior changes with clean-up, split it before it becomes hard to review.
## Explicit over magical
Configuration must be declared explicitly in `config/schema.py` Pydantic models. Error handling should raise clear exceptions rather than silently correcting bad input. Provider auto-detection exists, but every resolution path must be traceable from the factory to the concrete provider class.

# Common Gotchas
## Do not use `ruff format`
`CONTRIBUTING.md` mentions `ruff format`, but **do not run it** — it destroys git blame history. Only `ruff check` should be used.
## Config `${VAR}` References
`config/loader.py` resolves `${VAR}` patterns in `config.json` at load time. This is **not** a shell-like default-value syntax. If the environment variable is missing, `load_config` raises `ValueError` and the agent falls back to default configuration.
Example valid usage:
```json
{ "providers": { "openrouter": { "apiKey": "${OPENROUTER_KEY}" } } }
```
## Windows Compatibility
nanobot explicitly supports Windows. Key differences to keep in mind:
- `ExecTool` uses `cmd /c` on Windows instead of `sh -c` (`shell.py`).
- `cli/commands.py` forces `sys.stdout`/`stderr` to UTF-8 on startup to handle emoji and multilingual input.
- MCP stdio server commands are normalized for Windows path separators (`mcp.py`).
- Always use `pathlib.Path` for path manipulation; do not assume `/` separators.
## Prompt Templates
Agent system prompts and scenario-specific instructions live in `nanobot/templates/` as Jinja2 markdown files (`identity.md`, `platform_policy.md`, `HEARTBEAT.md`, `SOUL.md`, etc.). Changing these files alters agent behavior as directly as changing Python code. They are loaded by `utils/prompt_templates.py`.
Tool descriptions, skills, and replayed session history also shape model behavior. Treat changes to those surfaces like runtime code: keep them narrow, add a focused regression test when possible, and avoid teaching the model to repeat internal markers, local paths, or tool-call text.
## Context Pollution Persists
Anything written into memory, session history, or prompt inputs can be replayed into future LLM calls. Metadata such as timestamps, local media paths, tool-call echoes, and raw fallback dumps must be bounded and sanitized before they become examples for the model to imitate.
## Skills as Extension Point
Built-in skills live in `nanobot/skills/` (markdown + YAML frontmatter format). Agent capabilities that are "know-how" rather than code should be added as skills, not hardcoded into the agent loop. External skills can be published to and installed from ClawHub.
## Atomic Session Writes
`agent/memory.py` writes `history.jsonl` atomically (temp file + fsync + rename + directory fsync). This guarantees durability across crashes. Do not replace this with a plain `open(..., "w")` write.

# Security Boundaries
The agent operates with significant power (file system, shell, web). The following guards must not be bypassed when modifying related code.
## Workspace Restriction
Filesystem tools (`read_file`, `write_file`, `edit_file`, `list_dir`) resolve paths through `_resolve_path` (`agent/tools/filesystem.py`), which enforces that the resolved path must lie under `allowed_dir` (typically the configured workspace), plus the media upload directory (`get_media_dir()`) and any `extra_allowed_dirs`.
Shell execution (`ExecTool`, `agent/tools/shell.py`) also respects `restrict_to_workspace`: if enabled and `working_dir` is outside the workspace, the command is rejected before execution.
**Rule**: Any new path-handling logic must go through `_resolve_path` or perform an equivalent `allowed_dir` check.
## SSRF Protection
All outbound HTTP requests from agent tools must pass through `validate_url_target` (`security/network.py`). By default it blocks RFC1918 private addresses, link-local ranges, and cloud metadata endpoints (including `169.254.169.254`).
The only escape hatch is `configure_ssrf_whitelist(cidrs)`, which reads from `config.tools.ssrf_whitelist` at load time.
**Rule**: Do not add direct `httpx.get` / `requests.get` calls in tools. Route through the existing web fetch utilities or replicate the `validate_url_target` check.
## Shell Sandbox
`tools/sandbox.py` provides optional command wrapping. The only backend currently shipped is `bwrap` (bubblewrap), intended for containerized deployments. On Windows and bare-metal Linux without `bwrap`, commands run in the native shell with workspace restriction as the only guard.
**Rule**: If adding a new sandbox backend, implement `_wrap_<name>(command, workspace, cwd) -> str` and register it in `_BACKENDS`.

This file provides guidance to AI coding agents working with this repository.
## Project Overview
nanobot is a lightweight, open-source AI agent framework written in Python with a React/TypeScript WebUI. It centers around a small agent loop that receives messages from chat channels, invokes an LLM provider, executes tools, and manages session memory.
## Development Commands
```bash
# Python: run single test / lint
pytest tests/test_openai_api.py::test_function -v
ruff check nanobot/
# WebUI: dev server (proxies API/WS to gateway :8765), build, test
# Build outputs to ../nanobot/web/dist (bundled into the Python wheel)
cd webui && bun run dev # or NANOBOT_API_URL=... bun run dev
cd webui && bun run build
cd webui && bun run test
# Gateway
nanobot gateway
```
## High-Level Architecture
### Core Data Flow
Messages flow through an async `MessageBus` (`nanobot/bus/queue.py`) that decouples chat channels from the agent core:
1. **Channels** (`nanobot/channels/`) receive messages from external platforms and publish `InboundMessage` events to the bus.
2. **`AgentLoop`** (`nanobot/agent/loop.py`) consumes inbound messages, builds context, and coordinates the turn.
3. **`AgentRunner`** (`nanobot/agent/runner.py`) handles the actual LLM conversation loop: send messages to the provider, receive tool calls, execute tools, and stream responses.
4. Responses are published as `OutboundMessage` events back to the appropriate channel.
### Key Subsystems
- **Agent Loop** (`nanobot/agent/loop.py`, `runner.py`): The core processing engine. `AgentLoop` manages session keys, hooks, and context building. `AgentRunner` executes the multi-turn LLM conversation with tool execution.
- **LLM Providers** (`nanobot/providers/`): Provider implementations (Anthropic, OpenAI-compatible, OpenAI Responses API, Azure, Bedrock, GitHub Copilot, OpenAI Codex, etc.) built on a common base (`base.py`). Includes image generation (`image_generation.py`) and audio transcription (`transcription.py`). `factory.py` and `registry.py` handle instantiation and model discovery.
- **Channels** (`nanobot/channels/`): Platform integrations (Telegram, Discord, Slack, Feishu, Matrix, WhatsApp, QQ, WeChat, WeCom, DingTalk, Email, MoChat, MS Teams, WebSocket). `manager.py` discovers and coordinates them. Channels are auto-discovered via `pkgutil` scan + entry-point plugins.
- **Tools** (`nanobot/agent/tools/`): Agent capabilities exposed to the LLM: filesystem (read/write/edit/list), shell execution (with sandbox backends), web search/fetch, MCP servers, cron, notebook editing, subagent spawning, long-running tasks / sustained goals (`long_task.py`), image generation, and self-modification. Tools are auto-discovered via `pkgutil` scan + entry-point plugins.
- **Memory** (`nanobot/agent/memory.py`): Session history persistence with Dream two-phase memory consolidation. Uses atomic writes with fsync for durability.
- **Session Management** (`nanobot/session/`): Per-session history, context compaction, TTL-based auto-compaction (`manager.py`), and sustained goal state tracking (`goal_state.py`).
- **Config** (`nanobot/config/schema.py`, `loader.py`): Pydantic-based configuration loaded from `~/.nanobot/config.json`. Supports camelCase aliases for JSON compatibility.
- **Bridge** (`bridge/`): TypeScript services (e.g. WhatsApp bridge) bundled into the wheel via `pyproject.toml` `force-include`.
- **WebUI** (`webui/`): Vite-based React SPA that talks to the gateway over a WebSocket multiplex protocol. The dev server proxies `/api`, `/webui`, `/auth`, and WebSocket traffic to the gateway.
- **API Server** (`nanobot/api/server.py`): OpenAI-compatible HTTP API (`/v1/chat/completions`, `/v1/models`) for programmatic access.
- **Command Router** (`nanobot/command/`): Slash command routing and built-in command handlers.
- **Heartbeat** (`nanobot/templates/HEARTBEAT.md`): Periodic task list checked via `cron` jobs (legacy dedicated service removed).
- **Pairing** (`nanobot/pairing/`): DM sender approval store with persistent pairing codes per channel.
- **Skills** (`nanobot/skills/`): Built-in skill definitions (long-goal, cron, github, image-generation, etc.) loaded into agent context.
- **Security** (`nanobot/security/`): PTH file guard and other security measures activated at CLI entry.
### Entry Points
- **CLI**: `nanobot/cli/commands.py`
- **Python SDK**: `nanobot/nanobot.py`
## Project-Specific Notes
- Architecture constraints: [`.agent/design.md`](.agent/design.md)
- Security boundaries: [`.agent/security.md`](.agent/security.md)
- Common gotchas: [`.agent/gotchas.md`](.agent/gotchas.md)
## Branching Strategy
See [`CONTRIBUTING.md`](./CONTRIBUTING.md) for the full two-branch model (`main` vs `nightly`) and PR guidelines.
## Code Style
- Python 3.11+, asyncio throughout.
- Line length: 100.
- Linting: `ruff` with rules E, F, I, N, W (E501 ignored).
- pytest with `asyncio_mode = "auto"`.
## Common File Locations
- Config schema: `nanobot/config/schema.py`
- Provider base / new provider template: `nanobot/providers/base.py`
- Channel base / new channel template: `nanobot/channels/base.py`
- Tool registry: `nanobot/agent/tools/registry.py`
- WebUI dev proxy config: `webui/vite.config.ts`
- Tests mirror the `nanobot/` package structure.

### Starting Work
Before making changes, sync the target branch and create a topic branch from it.
For stable bug fixes and documentation-only changes, start from the latest `main`.
For experimental work, start from the latest `nightly`.
```bash
git fetch upstream
git switch main

uses a different remote name.
Keep unrelated local changes out of the topic branch. If your checkout already has
work in progress, use a separate worktree or finish that work before starting a
new branch.

## Progress, Tool Hints, and Reasoning
Besides normal assistant text, nanobot can emit low-emphasis trace blocks. These are intended for UI affordances like status rows, collapsible "used tools" groups, or reasoning/thinking blocks. Platforms that do not have a good place for them can ignore them safely.
### Progress and Tool Hints
Progress and tool hints arrive through the normal `send(msg)` path. Check `msg.metadata` before rendering:
```python
async def send(self, msg: OutboundMessage) -> None:
meta = msg.metadata or {}
if meta.get("_tool_hint"):
# A short tool breadcrumb, e.g. read_file("config.json")
await self._send_trace(msg.chat_id, msg.content, kind="tool")
return
if meta.get("_progress"):
# Generic non-final status, e.g. "Thinking..." or "Running command..."
await self._send_trace(msg.chat_id, msg.content, kind="progress")
return
await self._send_message(msg.chat_id, msg.content, media=msg.media)
```
Tool hints are off by default for most channels. Users can enable them globally or per channel:
```json
{
"channels": {
"sendToolHints": true,
"webhook": {
"enabled": true,
"sendToolHints": true
}
}
}
```
### Reasoning Blocks
Reasoning is delivered through dedicated optional hooks, not `send()`. Override `send_reasoning_delta()` and `send_reasoning_end()` if your platform can show model reasoning as a subdued/collapsible block. The default implementation is a no-op, so unsupported channels simply drop reasoning content.
```python
class WebhookChannel(BaseChannel):
name = "webhook"
display_name = "Webhook"
def __init__(self, config: Any, bus: MessageBus):
if isinstance(config, dict):
config = WebhookConfig(**config)
super().__init__(config, bus)
self._reasoning_buffers: dict[str, str] = {}
async def send_reasoning_delta(
self,
chat_id: str,
delta: str,
metadata: dict[str, Any] | None = None,
) -> None:
meta = metadata or {}
stream_id = str(meta.get("_stream_id") or chat_id)
self._reasoning_buffers[stream_id] = self._reasoning_buffers.get(stream_id, "") + delta
await self._update_reasoning_block(chat_id, self._reasoning_buffers[stream_id], final=False)
async def send_reasoning_end(
self,
chat_id: str,
metadata: dict[str, Any] | None = None,
) -> None:
meta = metadata or {}
stream_id = str(meta.get("_stream_id") or chat_id)
text = self._reasoning_buffers.pop(stream_id, "")
if text:
await self._update_reasoning_block(chat_id, text, final=True)
```
**Reasoning metadata flags:**
| Flag | Meaning |
|------|---------|
| `_reasoning_delta: True` | A reasoning/thinking chunk; `delta` contains the new text. |
| `_reasoning_end: True` | The current reasoning block is complete; `delta` is empty. |
| `_reasoning: True` | Legacy one-shot reasoning. `BaseChannel.send_reasoning()` converts it to delta + end. |
| `_stream_id` | Stable id for this assistant turn/segment. Use it to key buffers instead of only `chat_id`. |
Reasoning visibility is controlled by `showReasoning` globally or per channel:
```json
{
"channels": {
"showReasoning": true,
"webhook": {
"enabled": true,
"showReasoning": true
}
}
}
```
Recommended rendering:
- Render tool hints and progress as trace/status UI, not as normal assistant replies.
- Render reasoning with lower visual emphasis and collapse it after completion when the platform supports that.
- Keep reasoning separate from final answer text. A final answer still arrives through `send()` or `send_delta()`.

# Python SDK
> **Note:** This interface is currently an experiment in the latest source code version and is planned to officially ship in `v0.1.5`.
Use nanobot programmatically — load config, run the agent, get results.
## Quick Start
```python
import asyncio
from nanobot import Nanobot
async def main():
bot = Nanobot.from_config()
result = await bot.run("What time is it in Tokyo?")
print(result.content)
asyncio.run(main())
```
## API
### `Nanobot.from_config(config_path?, *, workspace?)`
Create a `Nanobot` from a config file.
| Param | Type | Default | Description |
|-------|------|---------|-------------|
| `config_path` | `str \| Path \| None` | `None` | Path to `config.json`. Defaults to `~/.nanobot/config.json`. |
| `workspace` | `str \| Path \| None` | `None` | Override workspace directory from config. |
Raises `FileNotFoundError` if an explicit path doesn't exist.
### `await bot.run(message, *, session_key?, hooks?)`
Run the agent once. Returns a `RunResult`.
| Param | Type | Default | Description |
|-------|------|---------|-------------|
| `message` | `str` | *(required)* | The user message to process. |
| `session_key` | `str` | `"sdk:default"` | Session identifier for conversation isolation. Different keys get independent history. |
| `hooks` | `list[AgentHook] \| None` | `None` | Lifecycle hooks for this run only. |
```python
# Isolated sessions — each user gets independent conversation history
await bot.run("hi", session_key="user-alice")
await bot.run("hi", session_key="user-bob")
```
### `RunResult`
| Field | Type | Description |
|-------|------|-------------|
| `content` | `str` | The agent's final text response. |
| `tools_used` | `list[str]` | Tool names invoked during the run. |
| `messages` | `list[dict]` | Raw message history (for debugging). |
## Hooks
Hooks let you observe or modify the agent loop without touching internals.
Subclass `AgentHook` and override any method:
| Method | When |
|--------|------|
| `before_iteration(ctx)` | Before each LLM call |
| `on_stream(ctx, delta)` | On each streamed token |
| `on_stream_end(ctx)` | When streaming finishes |
| `before_execute_tools(ctx)` | Before tool execution (inspect `ctx.tool_calls`) |
| `after_iteration(ctx, response)` | After each LLM response |
| `finalize_content(ctx, content)` | Transform final output text |
### Example: Audit Hook
```python
from nanobot.agent import AgentHook, AgentHookContext
class AuditHook(AgentHook):
def __init__(self):
self.calls = []
async def before_execute_tools(self, ctx: AgentHookContext) -> None:
for tc in ctx.tool_calls:
self.calls.append(tc.name)
print(f"[audit] {tc.name}({tc.arguments})")
hook = AuditHook()
result = await bot.run("List files in /tmp", hooks=[hook])
print(f"Tools used: {hook.calls}")
```
### Composing Hooks
Pass multiple hooks — they run in order, errors in one don't block others:
```python
result = await bot.run("hi", hooks=[AuditHook(), MetricsHook()])
```
Under the hood this uses `CompositeHook` for fan-out with error isolation.
### `finalize_content` Pipeline
Unlike the async methods (fan-out), `finalize_content` is a pipeline — each hook's output feeds the next:
```python
class Censor(AgentHook):
def finalize_content(self, ctx, content):
return content.replace("secret", "***") if content else content
```
## Full Example
```python
import asyncio
from nanobot import Nanobot
from nanobot.agent import AgentHook, AgentHookContext
class TimingHook(AgentHook):
async def before_iteration(self, ctx: AgentHookContext) -> None:
import time
ctx.metadata["_t0"] = time.time()
async def after_iteration(self, ctx, response) -> None:
import time
elapsed = time.time() - ctx.metadata.get("_t0", 0)
print(f"[timing] iteration took {elapsed:.2f}s")
async def main():
bot = Nanobot.from_config(workspace="/my/project")
result = await bot.run(
"Explain the main function",
hooks=[TimingHook()],
)
print(result.content)
asyncio.run(main())
```

**`reasoning_delta`** — incremental model reasoning / thinking chunk for the active assistant turn. Mirrors `delta` but targets the reasoning bubble above the answer rather than the answer body:
```json
{
"event": "reasoning_delta",
"chat_id": "uuid-v4",
"text": "Let me decompose ",
"stream_id": "r1"
}
```
**`reasoning_end`** — close marker for the active reasoning stream. WebUI uses this to lock the in-place bubble and switch from the shimmer header to a static collapsed state:
```json
{
"event": "reasoning_end",
"chat_id": "uuid-v4",
"stream_id": "r1"
}
```
Reasoning frames only flow when the channel's `showReasoning` is `true` (default) and the model returns reasoning content (DeepSeek-R1 / Kimi / MiMo / OpenAI reasoning models, Anthropic extended thinking, or inline `<think>` / `<thought>` tags). Models without reasoning produce zero `reasoning_delta` frames.
**`runtime_model_updated`** — broadcast when the gateway runtime model changes, for example after `/model <preset>`:
```json
{
"event": "runtime_model_updated",
"model_name": "openai/gpt-4.1-mini",
"model_preset": "fast"

```
`model_preset` is omitted when no named preset is active. WebUI clients use this event to keep the displayed model badge in sync across slash commands, config reloads, and settings changes.
**`attached`** — confirmation for `new_chat` / `attach` inbound envelopes (see [Multi-chat multiplexing](#multi-chat-multiplexing)):
```json
{"event": "attached", "chat_id": "uuid-v4"}
```
**`error`** — soft error for malformed inbound envelopes. The connection stays open:
```json
{"event": "error", "detail": "invalid chat_id"}
```
### Client → Server
**Legacy (default chat):** send a plain string, or a JSON object with a recognized text field:
Send plain text:
```json
"Hello nanobot!"
```
Or send a JSON object with a recognized text field:
```json
{"content": "Hello nanobot!"}
```
Recognized fields: `content`, `text`, `message` (checked in that order). Invalid JSON is treated as plain text. These frames route to the connection's default `chat_id` (the one announced in `ready`).
**Typed envelopes (multi-chat):** any JSON object with a string `type` field is a typed envelope:
| `type` | Fields | Effect |
|--------|--------|--------|
| `new_chat` | — | Server mints a new `chat_id`, subscribes this connection, replies with `attached`. |
| `attach` | `chat_id` | Subscribe to an existing `chat_id` (e.g. after a page reload). Replies with `attached`. |
| `message` | `chat_id`, `content` | Send `content` on `chat_id`. First use auto-attaches; no explicit `attach` needed. |

- Outstanding tokens are capped at 10,000. Requests beyond this return HTTP 429.
- Expired tokens are purged lazily on each issue or validation request.
## Multi-chat multiplexing
A single WebSocket can carry many concurrent chats. The server tracks `chat_id -> {connections}` as a fan-out set, so the same chat can also be mirrored across multiple connections (e.g. two browser tabs).
### Typical flow (web UI with a sidebar)
```text
client server
| --- connect --------------------> |
| <-- {"event":"ready", |
| "chat_id":"d3..."} (default)|
| |
| --- {"type":"new_chat"} ---------> |
| <-- {"event":"attached", |
| "chat_id":"a1..."} |
| |
| --- {"type":"message", |
| "chat_id":"a1...", |
| "content":"hi"} ------------> |
| <-- {"event":"delta", ...} |
| <-- {"event":"stream_end", ...} |
| |
| --- {"type":"attach", | # after page reload
| "chat_id":"a1..."} ---------> |
| <-- {"event":"attached", ...} |
```
### Rules
- Every outbound event carries `chat_id`. Clients must dispatch by that field.
- `chat_id` format: `^[A-Za-z0-9_:-]{1,64}$`. Non-matching values return `error`.
- `message` auto-attaches on first use — no separate `attach` is required for chats the server minted (`new_chat`) on the same connection.
- Errors (invalid envelope, unknown `type`, bad `chat_id`) are soft: the server replies with `{"event":"error","detail":"..."}` and keeps the connection open.
### Backward compatibility
Legacy clients that only send plain text or `{"content": ...}` keep working unchanged: those frames route to the connection's default `chat_id` (the one from `ready`). No config flag is needed.
### Security boundary
`chat_id` is a *capability*: anyone holding a valid WebSocket auth credential and the chat_id can attach to that conversation and see its output. This is safe for nanobot's local, single-user model. Multi-tenant deployments should namespace chat_ids per user (or introduce a per-tenant auth gate) — nanobot does not do this today.
## Security Notes
- **Timing-safe comparison**: Static token validation uses `hmac.compare_digest` to prevent timing attacks.
- **Defense in depth**: `allowFrom` is checked at both the HTTP handshake level and the message level.
- **chat_id as capability**: see [Multi-chat multiplexing](#multi-chat-multiplexing). Auth on the WebSocket handshake is the single line of defense; callers who pass it can attach to any chat_id they know.
- **Token isolation**: Each WebSocket connection gets a unique `chat_id`. Clients cannot access other sessions.
- **TLS enforcement**: When SSL is enabled, TLSv1.2 is the minimum allowed version.
- **Default-secure**: `websocketRequiresToken` defaults to `true`. Explicitly set it to `false` only on trusted networks.

| **Signal** | signal-cli daemon + phone number |
<details>
<summary><b>Telegram</b> (Recommended)</summary>
**1. Create a bot**
- Open Telegram, search `@BotFather`
- Send `/newbot`, follow prompts
- Copy the token
**2. Configure**
```json
{
"channels": {
"telegram": {
"enabled": true,
"token": "YOUR_BOT_TOKEN",
"allowFrom": ["YOUR_USER_ID"]
}
}
}
```
> You can find your **User ID** in Telegram settings. It is shown as `@yourUserId`.
> Copy this value **without the `@` symbol** and paste it into the config file.
**3. Run**
```bash
nanobot gateway
```
**Webhook mode (optional)**
Telegram uses long polling by default. To receive updates through a webhook, expose
a public HTTPS URL that forwards to nanobot's local listener and set `mode` to
`webhook`:
```json
{
"channels": {
"telegram": {
"enabled": true,
"token": "YOUR_BOT_TOKEN",
"mode": "webhook",
"webhookUrl": "https://example.com/telegram",
"webhookListenHost": "127.0.0.1",
"webhookListenPort": 8081,
"webhookPath": "/telegram",
"webhookSecretToken": "CHANGE_ME_RANDOM_SECRET",
"webhookMaxConnections": 4,
"allowFrom": ["YOUR_USER_ID"]
}
}
}
```
> `webhookSecretToken` is required in webhook mode. Do not expose the local
> webhook listener directly to the public internet without a reverse proxy or
> tunnel in front of it. TLS/Host policy is handled by your proxy; nanobot only
> listens on `webhookListenHost:webhookListenPort` and validates Telegram's
> webhook secret token. `webhookMaxConnections` defaults to `4`; nanobot
> still serializes Telegram updates per conversation before forwarding them to
> the agent.
>
> `webhookUrl` is the public HTTPS URL registered with Telegram.
> `webhookPath` is the local path nanobot listens on. They often use the same
> path, but may differ when a reverse proxy or tunnel rewrites the request path.

<details>
<summary><b>Mochat (Claw IM)</b></summary>
Uses **Socket.IO WebSocket** by default, with HTTP polling fallback.
**1. Ask nanobot to set up Mochat for you**
Simply send this message to nanobot (replace `xxx@xxx` with your real email):
```
Read https://raw.githubusercontent.com/HKUDS/MoChat/refs/heads/main/skills/nanobot/skill.md and register on MoChat. My Email account is xxx@xxx Bind me as your owner and DM me on MoChat.
```
nanobot will automatically register, configure `~/.nanobot/config.json`, and connect to Mochat.
**2. Restart gateway**
```bash
nanobot gateway
```
That's it — nanobot handles the rest!
<br>
<details>
<summary>Manual configuration (advanced)</summary>
If you prefer to configure manually, add the following to `~/.nanobot/config.json`:
> Keep `claw_token` private. It should only be sent in `X-Claw-Token` header to your Mochat API endpoint.
```json
{
"channels": {
"mochat": {
"enabled": true,
"base_url": "https://mochat.io",
"socket_url": "https://mochat.io",
"socket_path": "/socket.io",
"claw_token": "claw_xxx",
"agent_user_id": "6982abcdef",
"sessions": ["*"],
"panels": ["*"],
"reply_delay_mode": "non-mention",
"reply_delay_ms": 120000
}
}
}
```

<details>
<summary><b>Discord</b></summary>
**1. Create a bot**
- Go to https://discord.com/developers/applications
- Create an application → Bot → Add Bot
- Copy the bot token
**2. Enable intents**
- In the Bot settings, enable **MESSAGE CONTENT INTENT**
- (Optional) Enable **SERVER MEMBERS INTENT** if you plan to use allow lists based on member data
**3. Get your User ID**
- Discord Settings → Advanced → enable **Developer Mode**
- Right-click your avatar → **Copy User ID**
**4. Configure**
```json
{
"channels": {
"discord": {
"enabled": true,
"token": "YOUR_BOT_TOKEN",
"allowFrom": ["YOUR_USER_ID"],
"allowChannels": [],
"groupPolicy": "mention",
"streaming": true
}
}
}
```
> `groupPolicy` controls how the bot responds in group channels:
> - `"mention"` (default) — Only respond when @mentioned
> - `"open"` — Respond to all messages
> DMs always respond when the sender is in `allowFrom`.
> - If you set group policy to open create new threads as private threads and then @ the bot into it. Otherwise the thread itself and the channel in which you spawned it will spawn a bot session.
> `allowChannels` restricts the bot to specific Discord channel IDs. Empty (default) means respond in every channel the bot can see. Example: `["1234567890", "0987654321"]`. The filter applies after `allowFrom`, so both must pass. Discord threads under an allowed parent channel are also allowed; for Forum channels, allowing the parent Forum channel allows all threads/posts in that forum.
> `streaming` defaults to `true`. Disable it only if you explicitly want non-streaming replies.
**5. Invite the bot**
- OAuth2 → URL Generator
- Scopes: `bot`
- Bot Permissions: `Send Messages`, `Read Message History`
- Open the generated invite URL and add the bot to your server
**6. Run**
```bash
nanobot gateway
```
</details>
<details>
<summary><b>Matrix (Element)</b></summary>
Install Matrix dependencies first:
```bash
pip install nanobot-ai[matrix]
```
> [!NOTE]
> Matrix is not supported on Windows. `matrix-nio[e2e]` depends on
> `python-olm`, which has no pre-built Windows wheel and is skipped by the
> `matrix` extra on `sys_platform == 'win32'`. The command above will still
> succeed on Windows but without `matrix-nio` installed, so enabling the
> Matrix channel will fail at startup. Use macOS, Linux, or WSL2.
**1. Create/choose a Matrix account**
- Create or reuse a Matrix account on your homeserver (for example `matrix.org`).
- Confirm you can log in with Element.
**2. Get credentials**
- You need:
- `userId` (example: `@nanobot:matrix.org`)
- `password`
(Note: `accessToken` and `deviceId` are still supported for legacy reasons, but
for reliable encryption, password login is recommended instead. If the
`password` is provided, `accessToken` and `deviceId` will be ignored.)
**3. Configure**
```json
{
"channels": {
"matrix": {
"enabled": true,
"homeserver": "https://matrix.org",
"userId": "@nanobot:matrix.org",
"password": "mypasswordhere",
"e2eeEnabled": true,
"sasVerification": true,
"allowFrom": ["@your_user:matrix.org"],
"groupPolicy": "open",
"groupAllowFrom": [],
"allowRoomMentions": false,
"maxMediaBytes": 20971520
}
}
}
```
> Keep a persistent `matrix-store` — encrypted session state is lost if these change across restarts.
| Option | Description |
|--------|-------------|
| `allowFrom` | User IDs allowed to interact. Empty denies all; use `["*"]` to allow everyone. |
| `groupPolicy` | `open` (default), `mention`, or `allowlist`. |
| `groupAllowFrom` | Room allowlist (used when policy is `allowlist`). |
| `allowRoomMentions` | Accept `@room` mentions in mention mode. |
| `e2eeEnabled` | E2EE support (default `true`). Set `false` for plaintext-only. |
| `sasVerification` | Auto-complete SAS device verification requests from allowed users (default `false`). Useful for Element X, which does not expose manual trust for third-party devices. |
| `maxMediaBytes` | Max attachment size (default `20MB`). Set `0` to block all media. |
**4. Run**
```bash
nanobot gateway

<details>
<summary><b>Feishu</b></summary>
Uses **WebSocket** long connection — no public IP required.
**1. Create a Feishu bot**
- Visit [Feishu Open Platform](https://open.feishu.cn/app)
- Create a new app → Enable **Bot** capability
- **Permissions**:
- `im:message` (send messages) and `im:message.p2p_msg:readonly` (receive messages)
- **Streaming replies** (default in nanobot): add **`cardkit:card:write`** (often labeled **Create and update cards** in the Feishu developer console). Required for CardKit entities and streamed assistant text. Older apps may not have it yet — open **Permission management**, enable the scope, then **publish** a new app version if the console requires it.
- If you **cannot** add `cardkit:card:write`, set `"streaming": false` under `channels.feishu` (see below). The bot still works; replies use normal interactive cards without token-by-token streaming.
- **Events**: Add `im.message.receive_v1` (receive messages)
- Select **Long Connection** mode (requires running nanobot first to establish connection)
- Get **App ID** and **App Secret** from "Credentials & Basic Info"
- Publish the app
**2. Configure**
```json
{
"channels": {
"feishu": {
"enabled": true,
"appId": "cli_xxx",
"appSecret": "xxx",
"encryptKey": "",
"verificationToken": "",
"allowFrom": ["ou_YOUR_OPEN_ID"],
"groupPolicy": "mention",
"reactEmoji": "OnIt",
"doneEmoji": "DONE",
"toolHintPrefix": "🔧",
"streaming": true,
"domain": "feishu"
}
}
}
```
> `streaming` defaults to `true`. Use `false` if your app does not have **`cardkit:card:write`** (see permissions above).
> `encryptKey` and `verificationToken` are optional for Long Connection mode.
> `allowFrom`: Add your open_id (find it in nanobot logs when you message the bot). Use `["*"]` to allow all users.
> `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all group messages). Private chats always respond.
> `reactEmoji`: Emoji for "processing" status (default: `OnIt`). See [available emojis](https://open.larkoffice.com/document/server-docs/im-v1/message-reaction/emojis-introduce).
> `doneEmoji`: Optional emoji for "completed" status (e.g., `DONE`, `OK`, `HEART`). When set, bot adds this reaction after removing `reactEmoji`.
> `toolHintPrefix`: Prefix for inline tool hints in streaming cards (default: `🔧`).
> `domain`: `"feishu"` (default) for China (open.feishu.cn), `"lark"` for international Lark (open.larksuite.com).
**3. Run**
```bash
nanobot gateway
```
> [!TIP]
> Feishu uses WebSocket to receive messages — no webhook or public IP needed!
</details>
<details>
<summary><b>QQ (QQ单聊)</b></summary>
Uses **botpy SDK** with WebSocket — no public IP required. Currently supports **private messages only**.
**1. Register & create bot**
- Visit [QQ Open Platform](https://q.qq.com) → Register as a developer (personal or enterprise)
- Create a new bot application
- Go to **开发设置 (Developer Settings)** → copy **AppID** and **AppSecret**
**2. Set up sandbox for testing**
- In the bot management console, find **沙箱配置 (Sandbox Config)**
- Under **在消息列表配置**, click **添加成员** and add your own QQ number
- Once added, scan the bot's QR code with mobile QQ → open the bot profile → tap "发消息" to start chatting
**3. Configure**
> - `allowFrom`: Add your openid (find it in nanobot logs when you message the bot). Use `["*"]` for public access.
> - `msgFormat`: Optional. Use `"plain"` (default) for maximum compatibility with legacy QQ clients, or `"markdown"` for richer formatting on newer clients.
> - For production: submit a review in the bot console and publish. See [QQ Bot Docs](https://bot.q.qq.com/wiki/) for the full publishing flow.
```json
{
"channels": {
"qq": {
"enabled": true,
"appId": "YOUR_APP_ID",
"secret": "YOUR_APP_SECRET",
"allowFrom": ["YOUR_OPENID"],
"msgFormat": "plain"

<details>
<summary><b>Slack</b></summary>
Uses **Socket Mode** — no public URL required.
**1. Create a Slack app**
- Go to [Slack API](https://api.slack.com/apps) → **Create New App** → "From scratch"
- Pick a name and select your workspace
**2. Configure the app**
- **Socket Mode**: Toggle ON → Generate an **App-Level Token** with `connections:write` scope → copy it (`xapp-...`)
- **OAuth & Permissions**: Add bot scopes: `chat:write`, `reactions:write`, `app_mentions:read`, `files:read`, `files:write`, `channels:history`, `groups:history`, `im:history`, `mpim:history`
- **Event Subscriptions**: Toggle ON → Subscribe to bot events: `message.im`, `message.channels`, `app_mention` → Save Changes
- **App Home**: Scroll to **Show Tabs** → Enable **Messages Tab** → Check **"Allow users to send Slash commands and messages from the messages tab"**
- **Install App**: Click **Install to Workspace** → Authorize → copy the **Bot Token** (`xoxb-...`)
> `files:read` is required to read files users send to nanobot. `files:write` is required for nanobot to send images, videos, and other file uploads. If you add either scope later, reinstall the Slack app to the workspace and restart nanobot so it uses the updated bot token.
**3. Configure nanobot**
```json
{
"channels": {
"slack": {
"enabled": true,
"botToken": "xoxb-...",
"appToken": "xapp-...",
"allowFrom": ["YOUR_SLACK_USER_ID"],
"groupPolicy": "mention"
}
}
}
```
**4. Run**
```bash
nanobot gateway
```
DM the bot directly or @mention it in a channel — it should respond!
> [!TIP]
> - `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all channel messages), or `"allowlist"` (restrict to specific channels).
> - DM policy defaults to open. Set `"dm": {"enabled": false}` to disable DMs.
</details>
<details>
<summary><b>Email</b></summary>
Give nanobot its own email account. It polls **IMAP** for incoming mail and replies via **SMTP** — like a personal email assistant.
**1. Get credentials (Gmail example)**
- Create a dedicated Gmail account for your bot (e.g. `my-nanobot@gmail.com`)
- Enable 2-Step Verification → Create an [App Password](https://myaccount.google.com/apppasswords)
- Use this app password for both IMAP and SMTP
**2. Configure**
> - `consentGranted` must be `true` to allow mailbox access. This is a safety gate — set `false` to fully disable.
> - `allowFrom`: Add your email address. Use `["*"]` to accept emails from anyone.
> - `smtpUseTls` and `smtpUseSsl` default to `true` / `false` respectively, which is correct for Gmail (port 587 + STARTTLS). No need to set them explicitly.
> - Set `"autoReplyEnabled": false` if you only want to read/analyze emails without sending automatic replies.
> - `allowedAttachmentTypes`: Save inbound attachments matching these MIME types — `["*"]` for all, e.g. `["application/pdf", "image/*"]` (default `[]` = disabled).
> - `maxAttachmentSize`: Max size per attachment in bytes (default `2000000` / 2MB).
> - `maxAttachmentsPerEmail`: Max attachments to save per email (default `5`).
```json
{
"channels": {
"email": {

# In-Chat Commands
These commands work inside chat channels and interactive agent sessions:
| Command | Description |
|---------|-------------|
| `/new` | Stop current task and start a new conversation |
| `/stop` | Stop the current task |
| `/restart` | Restart the bot |
| `/status` | Show bot status |
| `/model` | Show the current model and available model presets |
| `/model <preset>` | Switch the runtime model preset for future turns |
| `/dream` | Run Dream memory consolidation now |
| `/dream-log` | Show the latest Dream memory change |
| `/dream-log <sha>` | Show a specific Dream memory change |
| `/dream-restore` | List recent Dream memory versions |
| `/dream-restore <sha>` | Restore memory to the state before a specific change |
| `/pairing` | List pending pairing requests |
| `/pairing approve <code>` | Approve a pairing code |
| `/pairing deny <code>` | Deny a pending pairing request |
| `/pairing revoke <user_id>` | Revoke a previously approved user on the current channel |
| `/pairing revoke <channel> <user_id>` | Revoke a previously approved user on a specific channel |
| `/help` | Show available in-chat commands |
## Pairing
When someone sends a DM to the bot and isn't on the allowlist — whether it's a new user or an existing user on a new channel — nanobot automatically replies with a **pairing code** (like `ABCD-EFGH`) that expires in 10 minutes. To grant them access:
```text
/pairing approve ABCD-EFGH
```
To see who's waiting, use `/pairing`. To remove someone later, use `/pairing revoke <user_id>` — you can find user IDs in the `/pairing list` output.
See [Configuration: Pairing](./configuration.md#pairing) for the full setup guide.
## Model Presets
Use `/model` to inspect the current runtime model:
```text
/model
```
The response shows the current model, the current preset, and the available preset names. `default` is always available and represents the model settings from `agents.defaults.*`.
To switch presets for future turns:
```text
/model fast
/model deep
/model default
```
Preset names come from the top-level `modelPresets` config. Switching is runtime-only: it does not rewrite `config.json`, and an in-progress turn keeps using the model it started with. See [Configuration: Model presets](./configuration.md#model-presets) for setup details.
## Periodic Tasks
The gateway wakes up every 30 minutes and checks `HEARTBEAT.md` in your workspace (`~/.nanobot/workspace/HEARTBEAT.md`). If the file has tasks under `## Active Tasks`, the agent executes them and delivers results to your most recently active chat channel. If there are no active tasks, the heartbeat is skipped silently.
**Setup:** edit `~/.nanobot/workspace/HEARTBEAT.md` (created automatically by `nanobot onboard`):
```markdown
## Active Tasks
- [ ] Check weather forecast and send a summary
- [ ] Scan inbox for urgent emails
```
The agent can also manage this file itself — ask it to "add a periodic task" and it will update `HEARTBEAT.md` for you. Completed tasks should be deleted from the file, not moved to another section.
> **Note:** The gateway must be running (`nanobot gateway`) and you must have chatted with the bot at least once so it knows which channel to deliver to.

# Deployment
## Docker
> [!TIP]
> The `-v ~/.nanobot:/home/nanobot/.nanobot` flag mounts your local config directory into the container, so your config and workspace persist across container restarts.
> The container runs as the non-root user `nanobot` (UID 1000) and reads config from `/home/nanobot/.nanobot`. Always mount your host config directory to `/home/nanobot/.nanobot`, not `/root/.nanobot`.
> If you get **Permission denied**, fix ownership on the host first: `sudo chown -R 1000:1000 ~/.nanobot`, or pass `--user $(id -u):$(id -g)` to match your host UID. Podman users can use `--userns=keep-id` instead.
>
> [!IMPORTANT]
> Official Docker usage currently means building from this repository with the included `Dockerfile`. Docker Hub images under third-party namespaces are not maintained or verified by HKUDS/nanobot; do not mount API keys or bot tokens into them unless you trust the publisher.
> [!IMPORTANT]
> The gateway and WebSocket channel default to `host: "127.0.0.1"` in `config.json` (set in `nanobot/config/schema.py`). Docker `-p` port forwarding cannot reach a container's loopback interface, so for the host or LAN to reach the exposed ports you must set both binds to `0.0.0.0` in `~/.nanobot/config.json` before starting the container. To serve the bundled WebUI from Docker, enable the WebSocket channel and protect bootstrap with a secret:
>
> ```json
> {
> "gateway": { "host": "0.0.0.0" },
> "channels": {
> "websocket": {
> "enabled": true,
> "host": "0.0.0.0",
> "port": 8765,
> "tokenIssueSecret": "your-secret-here"
> }
> }
> }
> ```
>
> When the WebSocket `host` is `0.0.0.0`, the channel refuses to start unless `token` or `tokenIssueSecret` is also configured — see [`webui/README.md`](../webui/README.md) for details.
### Docker Compose
```bash
docker compose run --rm nanobot-cli onboard # first-time setup
vim ~/.nanobot/config.json # add API keys
docker compose up -d nanobot-gateway # start gateway
```
```bash
docker compose run --rm nanobot-cli agent -m "Hello!" # run CLI
docker compose logs -f nanobot-gateway # view logs
docker compose down # stop
```
### Docker
```bash
# Build the image
docker build -t nanobot .
# Initialize config (first time only)
docker run -v ~/.nanobot:/home/nanobot/.nanobot --rm nanobot onboard
# Edit config on host to add API keys
vim ~/.nanobot/config.json
# Run gateway (connects to enabled channels, e.g. Telegram/Discord/Mochat).
# Mirrors the security caps and port mappings declared in docker-compose.yml:
# - `--cap-drop ALL --cap-add SYS_ADMIN` + unconfined apparmor/seccomp are required
# when `tools.exec.sandbox: "bwrap"` is enabled (bwrap needs CAP_SYS_ADMIN for
# user namespaces). Without them, `bwrap` exits with `clone3: Operation not permitted`.
# - `-p 8765:8765` exposes the WebSocket channel / WebUI alongside the gateway health
# endpoint on 18790.
docker run \
--cap-drop ALL --cap-add SYS_ADMIN \
--security-opt apparmor=unconfined \
--security-opt seccomp=unconfined \
-v ~/.nanobot:/home/nanobot/.nanobot \
-p 18790:18790 -p 8765:8765 \
nanobot gateway
# Or run a single command
docker run -v ~/.nanobot:/home/nanobot/.nanobot --rm nanobot agent -m "Hello!"
docker run -v ~/.nanobot:/home/nanobot/.nanobot --rm nanobot status
```
## Linux Service
Run the gateway as a systemd user service so it starts automatically and restarts on failure.
**1. Find the nanobot binary path:**
```bash
which nanobot # e.g. /home/user/.local/bin/nanobot
```
**2. Create the service file** at `~/.config/systemd/user/nanobot-gateway.service` (replace `ExecStart` path if needed):
```ini
[Unit]
Description=Nanobot Gateway
After=network.target
[Service]
Type=simple
ExecStart=%h/.local/bin/nanobot gateway
Restart=always
RestartSec=10
NoNewPrivileges=yes
ProtectSystem=strict
ReadWritePaths=%h
[Install]
WantedBy=default.target
```
**3. Enable and start:**
```bash
systemctl --user daemon-reload
systemctl --user enable --now nanobot-gateway
```
**Common operations:**
```bash
systemctl --user status nanobot-gateway # check status
systemctl --user restart nanobot-gateway # restart after config changes
journalctl --user -u nanobot-gateway -f # follow logs
```
If you edit the `.service` file itself, run `systemctl --user daemon-reload` before restarting.
> **Note:** User services only run while you are logged in. To keep the gateway running after logout, enable lingering:
>
> ```bash
> loginctl enable-linger $USER
> ```
## macOS LaunchAgent
Use a LaunchAgent when you want `nanobot gateway` to stay online after you log in, without keeping a terminal open.
**1. Get the absolute `nanobot` path:**
```bash
which nanobot # e.g. /Users/youruser/.local/bin/nanobot
```
Use that exact path in the plist. It keeps the Python environment from your install method.
**2. Create `~/Library/LaunchAgents/ai.nanobot.gateway.plist`:**
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>ai.nanobot.gateway</string>
<key>ProgramArguments</key>
<array>
<string>/Users/youruser/.local/bin/nanobot</string>
<string>gateway</string>
<string>--workspace</string>
<string>/Users/youruser/.nanobot/workspace</string>
</array>
<key>WorkingDirectory</key>
<string>/Users/youruser/.nanobot/workspace</string>
<key>RunAtLoad</key>
<true/>
<key>KeepAlive</key>
<dict>
<key>SuccessfulExit</key>
<false/>
</dict>
<key>StandardOutPath</key>
<string>/Users/youruser/.nanobot/logs/gateway.log</string>
<key>StandardErrorPath</key>
<string>/Users/youruser/.nanobot/logs/gateway.error.log</string>
</dict>
</plist>
```
**3. Load and start it:**
```bash
mkdir -p ~/Library/LaunchAgents ~/.nanobot/logs
launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/ai.nanobot.gateway.plist
launchctl enable gui/$(id -u)/ai.nanobot.gateway
launchctl kickstart -k gui/$(id -u)/ai.nanobot.gateway
```
**Common operations:**
```bash
launchctl list | grep ai.nanobot.gateway
launchctl kickstart -k gui/$(id -u)/ai.nanobot.gateway # restart
launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/ai.nanobot.gateway.plist
```
After editing the plist, run `launchctl bootout ...` and `launchctl bootstrap ...` again.
> **Note:** if startup fails with "address already in use", stop the manually started `nanobot gateway` process first.

# Image Generation
nanobot can generate and edit images through the `generate_image` tool. In the WebUI, users can enable **Image Generation** from the composer, choose an aspect ratio, and keep iterating on generated images inside the same chat.
The feature is disabled by default. Enable it in `~/.nanobot/config.json`, configure a supported image provider, then restart the gateway.
## Quick Setup
```json
{
"providers": {
"openrouter": {
"apiKey": "${OPENROUTER_API_KEY}"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "openrouter",
"model": "openai/gpt-5.4-image-2"
}
}
}
```
See [Provider Notes](#provider-notes) for AIHubMix, MiniMax, Gemini, Ollama, StepFun, and Zhipu configuration examples.
> [!TIP]
> Prefer environment variables for API keys. nanobot resolves `${VAR_NAME}` values from the environment at startup.
## WebUI Usage
In the WebUI composer:
1. Click **Image Generation**.
2. Choose an aspect ratio: `Auto`, `1:1`, `3:4`, `9:16`, `4:3`, or `16:9`.
3. Describe the image or the edit you want.
4. Attach reference images when editing an existing image.
Generated images are rendered as assistant media in the chat. Follow-up prompts such as "make it warmer", "change the background", or "try a 16:9 version" can reuse the most recent generated artifact.
The WebUI hides provider storage details from the user. The agent sees the saved artifact path internally and can pass it back to `generate_image` as `reference_images` for iterative edits.
## Configuration Reference
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `tools.imageGeneration.enabled` | boolean | `false` | Register the `generate_image` tool |
| `tools.imageGeneration.provider` | string | `"openrouter"` | Image provider name. Supported values: `openrouter`, `aihubmix`, `minimax`, `gemini`, `ollama`, `stepfun`, `zhipu` |
| `tools.imageGeneration.model` | string | `"openai/gpt-5.4-image-2"` | Provider model name |
| `tools.imageGeneration.defaultAspectRatio` | string | `"1:1"` | Default ratio when the prompt/tool call does not specify one |
| `tools.imageGeneration.defaultImageSize` | string | `"1K"` | Default size hint, for example `1K`, `2K`, `4K`, or `1024x1024` |
| `tools.imageGeneration.maxImagesPerTurn` | number | `4` | Maximum `count` accepted by one tool call. Valid range: `1` to `8` |
| `tools.imageGeneration.saveDir` | string | `"generated"` | Relative directory under nanobot's media directory for generated artifacts |
Provider settings reuse normal provider config fields:
| Option | Description |
|--------|-------------|
| `providers.<name>.apiKey` | Provider API key. Prefer `${ENV_VAR}` |
| `providers.<name>.apiBase` | Optional custom base URL |
| `providers.<name>.extraHeaders` | Headers merged into provider requests |
| `providers.<name>.extraBody` | Extra JSON fields merged into provider request bodies |
Both camelCase and snake_case config keys are accepted, but docs use camelCase to match `config.json`.
## Provider Notes
### OpenRouter
OpenRouter uses a chat-completions style image response. Configure:
```json
{
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "openrouter",
"model": "openai/gpt-5.4-image-2"
}
}
}
```
Use a model that supports image generation and image editing if you want reference-image edits.
### AIHubMix
AIHubMix `gpt-image-2-free` is supported through AIHubMix's unified predictions API. Internally nanobot calls:
```text
/v1/models/openai/gpt-image-2-free/predictions
```
Configure:
```json
{
"providers": {
"aihubmix": {
"apiKey": "${AIHUBMIX_API_KEY}",
"extraBody": {
"quality": "low"
}
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "aihubmix",
"model": "gpt-image-2-free"
}
}
}
```
`quality: low` is optional. It can make free image models faster and less likely to time out, but it is not required for correctness.
### MiniMax
MiniMax `image-01` supports text-to-image and reference-image (subject reference) edits. Supported aspect ratios are `1:1`, `16:9`, `4:3`, `3:2`, `2:3`, `3:4`, `9:16`, and `21:9`.
```json
{
"providers": {
"minimax": {
"apiKey": "${MINIMAX_API_KEY}"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "minimax",
"model": "image-01",
"defaultAspectRatio": "1:1"
}
}
}
```
### Gemini
nanobot supports two Gemini image generation model families via Google's Generative Language API:
| Model | Endpoint | Reference images |
|-------|----------|-----------------|
| `imagen-4.0-generate-001` | `:predict` | Not supported by this integration |
| `gemini-2.5-flash-image` | `:generateContent` | Supported |
For reference-image edits, use a Gemini Flash image model:
```json
{
"providers": {
"gemini": {
"apiKey": "${GEMINI_API_KEY}"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "gemini",
"model": "gemini-2.5-flash-image"
}
}
}
```
Imagen 4 supports the aspect ratios `1:1`, `9:16`, `16:9`, `3:4`, and `4:3`. Unsupported ratios are ignored and the model uses its default. The `defaultImageSize` setting has no effect on Gemini models; sizing is controlled by `defaultAspectRatio` only. Reference images passed with an Imagen model are ignored (with a warning logged).
### Ollama
Ollama's experimental native image generation API works with local servers and hosted ollama.com models. Local access at `http://localhost:11434/api` does not require an API key; set `providers.ollama.apiKey` only when targeting `https://ollama.com/api`.
```json
{
"providers": {
"ollama": {
"apiBase": "http://localhost:11434/api"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "ollama",
"model": "x/z-image-turbo",
"defaultAspectRatio": "16:9",
"defaultImageSize": "2K"
}
}
}
```
Ollama maps `defaultAspectRatio` and `defaultImageSize` to native `width` and `height` values. Reference images are not supported by this integration.
### StepFun
StepFun (阶跃星辰) `step-image-edit-2` supports text-to-image generation. The `step-1x-medium` variant additionally supports **style-reference** image edits, where a reference image guides the visual style of the output.
Supported aspect ratios: `1:1`, `16:9`, `9:16`, `3:4`, `4:3`. Sizes are specified as `WIDTHxHEIGHT` (e.g. `1024x1024`, `1280x800`, `800x1280`).
```json
{
"providers": {
"stepfun": {
"apiKey": "${STEPFUN_API_KEY}"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "stepfun",
"model": "step-image-edit-2"
}
}
}
```
> [!NOTE]
> The StepFun provider reuses the existing `providers.stepfun` config block (the same one used for StepFun's LLM API). Set `providers.stepfun.apiKey` once and it is shared between text and image generation.
>
> When `step-image-edit-2` is used, `reference_images` are ignored (the model does not support style reference). Switch to `step-1x-medium` to use reference-image-guided generation.
#### StepPlan (Subscription)
StepPlan is StepFun's subscription tier and uses a different API base URL. The image generation endpoint path is the same — just override `apiBase`:
```json
{
"providers": {
"stepfun": {
"apiKey": "${STEPFUN_API_KEY}",
"apiBase": "https://api.stepfun.com/step_plan/v1"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "stepfun",
"model": "step-image-edit-2"
}
}
}
```
`apiBase` takes precedence over the registry default, so with the StepPlan base URL configured, image requests are sent to `https://api.stepfun.com/step_plan/v1/images/generations` — the same path prefix used for LLM calls. The API key is shared with the standard StepFun provider.
### Zhipu
Zhipu (智谱) `glm-image` model supports text-to-image generation. The API returns temporary image URLs (valid for 30 days); nanobot downloads and re-encodes them as base64 data URLs.
Supported aspect ratios: `1:1`, `16:9`, `9:16`, `3:4`, `4:3`. Sizes can be specified as `WIDTHxHEIGHT` (e.g. `1280x1280`, `1728x960`) or using aspect ratio presets.
```json
{
"providers": {
"zhipu": {
"apiKey": "${ZAI_API_KEY}"
}
},
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "zhipu",
"model": "glm-image"
}
}
}
```
Other supported models: `cogview-4`, `cogview-4-250304`, `cogview-3-flash`. Reference images are not supported by this integration.
## Artifacts
Generated images are stored under the active nanobot instance's media directory:
```text
~/.nanobot/media/generated/YYYY-MM-DD/img_<id>.<ext>
~/.nanobot/media/generated/YYYY-MM-DD/img_<id>.json
```
For non-default config locations, the media directory is relative to the active config file's directory.
The JSON sidecar stores:
| Field | Meaning |
|-------|---------|
| `id` | Short generated image id, such as `img_ab12cd34ef56` |
| `path` | Local image path used internally for follow-up edits |
| `mime` | Detected image MIME type |
| `prompt` | Prompt used for the generation |
| `model` | Provider model |
| `provider` | Provider name |
| `source_images` | Reference image paths used for edits |
| `created_at` | Creation timestamp |
Do not paste base64 image payloads into chat. The agent should keep local artifact paths internal unless the user explicitly asks for debugging details.
## Prompting
Good image prompts include:
- Subject and scene.
- Composition, camera, or layout.
- Style, mood, lighting, and color palette.
- Exact text that must appear in the image, quoted.
- Constraints such as "keep the same character" or "preserve the logo".
Example:
```text
A minimal app icon for nanobot: friendly robot head, rounded square, soft blue and white palette, clean vector style, no text
```
For edits, describe what should change and what must stay fixed:
```text
Use the reference image. Keep the same robot and composition, change the palette to warm orange, and add a subtle sunrise background.
```
## Troubleshooting
| Symptom | Check |
|---------|-------|
| `generate_image` is not available | Set `tools.imageGeneration.enabled` to `true` and restart the gateway |
| Missing API key error | Configure `providers.<provider>.apiKey`; if using `${VAR_NAME}`, confirm the environment variable is visible to the gateway process |
| `unsupported image generation provider` | Use `openrouter`, `aihubmix`, `minimax`, `gemini`, `ollama`, `stepfun`, or `zhipu` |
| AIHubMix says `Incorrect model ID` | Use `model: "gpt-image-2-free"`; nanobot expands it to the required `openai/gpt-image-2-free` model path internally |
| Generation times out | Try a smaller/default image size, set AIHubMix `extraBody.quality` to `"low"`, or retry later |
| Reference image rejected | Reference image paths must be inside the workspace or nanobot media directory and must be valid image files |

# Multiple Instances
Run multiple nanobot instances simultaneously with separate configs and runtime data. Use `--config` as the main entrypoint. Optionally pass `--workspace` during `onboard` when you want to initialize or update the saved workspace for a specific instance.
## Quick Start
If you want each instance to have its own dedicated workspace from the start, pass both `--config` and `--workspace` during onboarding.
**Initialize instances:**
```bash
# Create separate instance configs and workspaces
nanobot onboard --config ~/.nanobot-telegram/config.json --workspace ~/.nanobot-telegram/workspace
nanobot onboard --config ~/.nanobot-discord/config.json --workspace ~/.nanobot-discord/workspace
nanobot onboard --config ~/.nanobot-feishu/config.json --workspace ~/.nanobot-feishu/workspace
```
**Configure each instance:**
Edit `~/.nanobot-telegram/config.json`, `~/.nanobot-discord/config.json`, etc. with different channel settings. The workspace you passed during `onboard` is saved into each config as that instance's default workspace.
**Run instances:**
```bash
# Instance A - Telegram bot
nanobot gateway --config ~/.nanobot-telegram/config.json
# Instance B - Discord bot
nanobot gateway --config ~/.nanobot-discord/config.json
# Instance C - Feishu bot with custom port
nanobot gateway --config ~/.nanobot-feishu/config.json --port 18792
```
## Path Resolution
When using `--config`, nanobot derives its runtime data directory from the config file location. The workspace still comes from `agents.defaults.workspace` unless you override it with `--workspace`.
To open a CLI session against one of these instances locally:
```bash
nanobot agent -c ~/.nanobot-telegram/config.json -m "Hello from Telegram instance"
nanobot agent -c ~/.nanobot-discord/config.json -m "Hello from Discord instance"
# Optional one-off workspace override
nanobot agent -c ~/.nanobot-telegram/config.json -w /tmp/nanobot-telegram-test
```
> `nanobot agent` starts a local CLI agent using the selected workspace/config. It does not attach to or proxy through an already running `nanobot gateway` process.
| Component | Resolved From | Example |
|-----------|---------------|---------|
| **Config** | `--config` path | `~/.nanobot-A/config.json` |
| **Workspace** | `--workspace` or config | `~/.nanobot-A/workspace/` |
| **Cron Jobs** | config directory | `~/.nanobot-A/cron/` |
| **Media / runtime state** | config directory | `~/.nanobot-A/media/` |
## How It Works
- `--config` selects which config file to load
- By default, the workspace comes from `agents.defaults.workspace` in that config
- If you pass `--workspace`, it overrides the workspace from the config file
## Minimal Setup
1. Copy your base config into a new instance directory.
2. Set a different `agents.defaults.workspace` for that instance.
3. Start the instance with `--config`.
Example config:
```json
{
"agents": {
"defaults": {
"workspace": "~/.nanobot-telegram/workspace",
"model": "anthropic/claude-sonnet-4-6"
}
},
"channels": {
"telegram": {
"enabled": true,
"token": "YOUR_TELEGRAM_BOT_TOKEN"
}
},
"gateway": {
"host": "127.0.0.1",
"port": 18790
}
}
```
Start separate instances:
```bash
nanobot gateway --config ~/.nanobot-telegram/config.json
nanobot gateway --config ~/.nanobot-discord/config.json
```
Each gateway instance also exposes a lightweight HTTP health endpoint on
`gateway.host:gateway.port`. By default, the gateway binds to `127.0.0.1`,
so the endpoint stays local unless you explicitly set `gateway.host` to a
public or LAN-facing address.
- `GET /health` returns `{"status":"ok"}`
- Other paths return `404`
Override workspace for one-off runs when needed:
```bash
nanobot gateway --config ~/.nanobot-telegram/config.json --workspace /tmp/nanobot-telegram-test
```
## Common Use Cases
- Run separate bots for Telegram, Discord, Feishu, and other platforms
- Keep testing and production instances isolated
- Use different models or providers for different teams
- Serve multiple tenants with separate configs and runtime data
## Notes
- Each instance must use a different port if they run at the same time
- Use a different workspace per instance if you want isolated memory, sessions, and skills
- `--workspace` overrides the workspace defined in the config file
- Cron jobs and runtime media/state are derived from the config directory

# My Tool
Let the agent sense and adjust its own runtime state — like asking a coworker "are you busy? can you switch to a bigger monitor?"
## Why You Need It
Normal tools let the agent operate on the outside world (read/write files, search code). But the agent knows nothing about itself — it doesn't know which model it's running on, how many iterations are left, or how many tokens it has consumed.
My tool fills this gap. With it, the agent can:
- **Know who it is**: What model am I using? Where is my workspace? How many iterations remain?
- **Adapt on the fly**: Complex task? Expand the context window. Simple chat? Switch to a faster model.
- **Remember across turns**: Store notes in your scratchpad that persist into the next conversation turn.
## Configuration
Enabled by default (read-only mode). The agent can check its state but not set it.
```yaml
tools:
my:
enable: true # default: true
allow_set: false # default: false (read-only)
```
To allow the agent to set its configuration (e.g. switch models, adjust parameters), set `tools.my.allow_set: true`.
Legacy `tools.myEnabled` / `tools.mySet` keys are auto-migrated on load, and
rewritten in-place the next time `nanobot onboard` refreshes the config.
All modifications are held in memory only — restart restores defaults.
---
## check — Check "my" current state
Without parameters, returns a key config overview:
```text
my(action="check")
# → max_iterations: 40
# context_window_tokens: 65536
# model: 'anthropic/claude-sonnet-4-20250514'
# workspace: PosixPath('/tmp/workspace')
# provider_retry_mode: 'standard'
# max_tool_result_chars: 16000
# _current_iteration: 3
# _last_usage: {'prompt_tokens': 45000, 'completion_tokens': 8000}
# Note: prompt_tokens is cumulative across all turns, not current context window occupancy.
```
With a key parameter, drill into a specific config:
```text
my(action="check", key="_last_usage.prompt_tokens")
# → How many prompt tokens I've used so far
my(action="check", key="model")
# → What model I'm currently running on
my(action="check", key="web_config.enable")
# → Whether web search is enabled
```
### What you can do with it
| Scenario | How |
|----------|-----|
| "What model are you using?" | `check("model")` |
| "How many more tool calls can you make?" | `check("max_iterations")` minus `check("_current_iteration")` |
| "How many tokens has this conversation used?" | `check("_last_usage")` — cumulative across all turns |
| "Where is your working directory?" | `check("workspace")` |
| "Show me your full config" | `check()` |
| "Are there any subagents running?" | `check("subagents")` — shows phase, iteration, elapsed time, tool events |
---
## set — Runtime tuning
Changes take effect immediately, no restart required.
```text
my(action="set", key="max_iterations", value=80)
# → Bump iteration limit from 40 to 80
my(action="set", key="model", value="fast-model")
# → Switch to a faster model
my(action="set", key="context_window_tokens", value=131072)
# → Expand context window for long documents
```
You can also store custom state in your scratchpad:
```text
my(action="set", key="current_project", value="nanobot")
my(action="set", key="user_style_preference", value="concise")
my(action="set", key="task_complexity", value="high")
# → These values persist into the next conversation turn
```
### Protected parameters
These parameters have type and range validation — invalid values are rejected:
| Parameter | Type | Range | Purpose |
|-----------|------|-------|---------|
| `max_iterations` | int | 1100 | Max tool calls per conversation turn |
| `context_window_tokens` | int | 4,0961,000,000 | Context window size |
| `model` | str | non-empty | LLM model to use |
Other parameters (e.g. `workspace`, `provider_retry_mode`, `max_tool_result_chars`) can be set freely, as long as the value is JSON-safe.

## Practical Scenarios
### "This task is complex, I need more room"
```text
Agent: This codebase is large, let me expand my context window to handle it.
→ my(action="set", key="context_window_tokens", value=131072)
```
### "Simple question, don't waste compute"
```text
Agent: This is a straightforward question, let me switch to a faster model.
→ my(action="set", key="model", value="fast-model")
```
### "Remember user preferences across turns"
```text
Turn 1: my(action="set", key="user_prefers_concise", value=True)
Turn 2: my(action="check", key="user_prefers_concise")
# → True (still remembers the user likes concise replies)
```
### "Self-diagnosis"
```text
User: "Why aren't you searching the web?"
Agent: Let me check my web config.
→ my(action="check", key="web_config.enable")
# → False
Agent: Web search is disabled — please set web.enable: true in your config.
```
### "Token budget management"
```text
Agent: Let me check how much budget I have left.
→ my(action="check", key="_last_usage")
# → {"prompt_tokens": 45000, "completion_tokens": 8000}
Agent: I've used ~53k tokens total so far. I'll keep my remaining replies concise.
```
### "Subagent monitoring"
```text
Agent: Let me check on the background tasks.
→ my(action="check", key="subagents")
# → 2 subagent(s):
# [task-1] 'Code review'
# phase: running, iteration: 5, elapsed: 12.3s
# tools: read(✓), grep(✓)
# usage: {'prompt_tokens': 8000, 'completion_tokens': 1200}
# [task-2] 'Write tests'
# phase: pending, iteration: 0, elapsed: 0.2s
# tools: none
Agent: The code review is progressing well. The test task hasn't started yet.
```
---
## Safety Mechanisms
Core design principle: **All modifications live in memory only. Restart restores defaults.** The agent cannot cause persistent damage.
### Off-limits (BLOCKED)
Cannot be checked or modified — fully hidden:
| Category | Attributes | Reason |
|----------|-----------|--------|
| Core infrastructure | `bus`, `provider`, `_running` | Changes would crash the system |
| Tool registry | `tools` | Must not remove its own tools |
| Subsystems | `runner`, `sessions`, `consolidator`, etc. | Affects other users/sessions |
| Sensitive data | `_mcp_servers`, `_pending_queues`, etc. | Contains credentials and message routing |
| Security boundaries | `restrict_to_workspace`, `channels_config` | Bypassing would violate isolation |
| Python internals | `__class__`, `__dict__`, etc. | Prevents sandbox escape |
### Read-only (check only)
Can be checked but not set:
| Category | Attributes | Reason |
|----------|-----------|--------|
| Subagent manager | `subagents` | Observable, but replacing breaks the system |
| Execution config | `exec_config` | Can check sandbox/enable status, cannot change it |
| Web config | `web_config` | Can check enable status, cannot change it |
| Iteration counter | `_current_iteration` | Updated by runner only |
### Sensitive field protection
Sub-fields matching sensitive names (`api_key`, `password`, `secret`, `token`, etc.) are blocked from both check and set, regardless of parent path. This prevents credential leaks via dot-path traversal (e.g. `web_config.search.api_key`).

# OpenAI-Compatible API
nanobot can expose a minimal OpenAI-compatible endpoint for local integrations:
```bash
pip install "nanobot-ai[api]"
nanobot serve
```
By default, the API binds to `127.0.0.1:8900`. You can change this in `config.json`.
## Behavior
- Session isolation: pass `"session_id"` in the request body to isolate conversations; omit for a shared default session (`api:default`)
- Single-message input: each request must contain exactly one `user` message
- Fixed model: omit `model`, or pass the same model shown by `/v1/models`
- Streaming: set `stream=true` to receive Server-Sent Events (`text/event-stream`) with OpenAI-compatible delta chunks, terminated by `data: [DONE]`; omit or set `stream=false` for a single JSON response
- **File uploads**: supports images, PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx) via JSON base64 or `multipart/form-data` (max 10MB per file)
- API requests run in the synthetic `api` channel, so the `message` tool does **not** automatically deliver to Telegram/Discord/etc. To proactively send to another chat, call `message` with an explicit `channel` and `chat_id` for an enabled channel.
Example tool call for cross-channel delivery from an API session:
```json
{
"content": "Build finished successfully.",
"channel": "telegram",
"chat_id": "123456789"
}
```
If `channel` points to a channel that is not enabled in your config, nanobot will queue the outbound event but no platform delivery will occur.
## Endpoints
- `GET /health`
- `GET /v1/models`
- `POST /v1/chat/completions`
## curl
```bash
curl http://127.0.0.1:8900/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"messages": [{"role": "user", "content": "hi"}],
"session_id": "my-session"
}'
```
## File Upload (JSON base64)
Send images inline using the OpenAI multimodal content format:
```bash
curl http://127.0.0.1:8900/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"messages": [{"role": "user", "content": [
{"type": "text", "text": "Describe this image"},
{"type": "image_url", "image_url": {"url": "data:image/png;base64,iVBOR..."}}
]}]
}'
```
## File Upload (multipart/form-data)
Upload any supported file type (images, PDF, Word, Excel, PPT) via multipart:
```bash
# Single file
curl http://127.0.0.1:8900/v1/chat/completions \
-F "message=Summarize this report" \
-F "files=@report.docx"
# Multiple files with session isolation
curl http://127.0.0.1:8900/v1/chat/completions \
-F "message=Compare these files" \
-F "files=@chart.png" \
-F "files=@data.xlsx" \
-F "session_id=my-session"
```
Supported file types:
- **Images**: PNG, JPEG, GIF, WebP (sent to AI as base64 for vision analysis)
- **Documents**: PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx) (text extracted and sent to AI)
- **Text**: TXT, Markdown, CSV, JSON, etc. (read directly)
## Python (`requests`)
```python
import requests
resp = requests.post(
"http://127.0.0.1:8900/v1/chat/completions",
json={
"messages": [{"role": "user", "content": "hi"}],
"session_id": "my-session", # optional: isolate conversation
},
timeout=120,
)
resp.raise_for_status()
print(resp.json()["choices"][0]["message"]["content"])

## Python (`openai`)
```python
from openai import OpenAI

api_key="dummy",
)
resp = client.chat.completions.create(

# Python SDK
Use nanobot as a library — no CLI, no gateway, just Python.
## Quick Start
```python
import asyncio
from nanobot import Nanobot
async def main() -> None:
bot = Nanobot.from_config()
result = await bot.run("What time is it in Tokyo?")
print(result.content)
asyncio.run(main())
```
`Nanobot.from_config()` reuses your normal `~/.nanobot/config.json`, so the SDK follows the same provider, model, tools, and workspace defaults as the CLI unless you override them.
## Common Patterns
### Use a specific config or workspace
```python
from nanobot import Nanobot
bot = Nanobot.from_config(
config_path="~/.nanobot/config.json",
workspace="/my/project",
)
```
### Isolate conversations with `session_key`
Different session keys keep independent conversation history:
```python
await bot.run("hi", session_key="user-alice")
await bot.run("hi", session_key="task-42")
```
### Attach hooks for observability
Hooks let you inspect tool calls, streaming, and iteration state without modifying nanobot internals:
```python
from nanobot.agent import AgentHook, AgentHookContext
class AuditHook(AgentHook):
async def before_execute_tools(self, context: AgentHookContext) -> None:
for tc in context.tool_calls:
print(f"[tool] {tc.name}")
result = await bot.run("Review this change", hooks=[AuditHook()])
```
## API Reference
### `Nanobot.from_config(config_path=None, *, workspace=None)`
Create a `Nanobot` instance from a config file.
| Param | Type | Default | Description |
|-------|------|---------|-------------|
| `config_path` | `str \| Path \| None` | `None` | Path to `config.json`. Defaults to `~/.nanobot/config.json`. |
| `workspace` | `str \| Path \| None` | `None` | Override the workspace directory from config. |
Raises `FileNotFoundError` if an explicit config path does not exist.
### `await bot.run(message, *, session_key="sdk:default", hooks=None)`
Run the agent once and return a `RunResult`.
| Param | Type | Default | Description |
|-------|------|---------|-------------|
| `message` | `str` | *(required)* | The user message to process. |
| `session_key` | `str` | `"sdk:default"` | Session identifier for conversation isolation. Different keys get independent history. |
| `hooks` | `list[AgentHook] \| None` | `None` | Lifecycle hooks for this run only. |
### `RunResult`
| Field | Type | Description |
|-------|------|-------------|
| `content` | `str` | The agent's final text response. |
| `tools_used` | `list[str]` | Reserved for richer SDK introspection; may be empty in current versions. |
| `messages` | `list[dict]` | Reserved for richer SDK introspection; may be empty in current versions. |
## Hooks
Hooks let you observe or customize the agent loop. Subclass `AgentHook` and override the methods you need.
### Hook lifecycle
| Method | When |
|--------|------|
| `wants_streaming()` | Return `True` if you want token-by-token `on_stream()` callbacks |
| `before_iteration(context)` | Before each LLM call |
| `on_stream(context, delta)` | On each streamed token when streaming is enabled |
| `on_stream_end(context, *, resuming)` | When streaming finishes |
| `before_execute_tools(context)` | Before tool execution |
| `after_iteration(context)` | After each iteration |
| `finalize_content(context, content)` | Transform final output text |
Useful fields on `AgentHookContext` include:
- `iteration`
- `messages`
- `response`
- `usage`
- `tool_calls`
- `tool_results`
- `tool_events`
- `final_content`
- `stop_reason`
- `error`
### Example: audit tool calls
```python
from nanobot.agent import AgentHook, AgentHookContext
class AuditHook(AgentHook):
def __init__(self) -> None:
super().__init__()
self.calls: list[str] = []
async def before_execute_tools(self, context: AgentHookContext) -> None:
for tc in context.tool_calls:
self.calls.append(tc.name)
print(f"[audit] {tc.name}({tc.arguments})")
```
```python
hook = AuditHook()
result = await bot.run("List files in /tmp", hooks=[hook])
print(result.content)
print(f"Tools observed: {hook.calls}")
```
### Example: receive streaming tokens
```python
from nanobot.agent import AgentHook, AgentHookContext
class StreamingHook(AgentHook):
def wants_streaming(self) -> bool:
return True
async def on_stream(self, context: AgentHookContext, delta: str) -> None:
print(delta, end="", flush=True)
async def on_stream_end(self, context: AgentHookContext, *, resuming: bool) -> None:
print()
```
### Compose multiple hooks
Pass multiple hooks when you want to combine behaviors:
```python
result = await bot.run("hi", hooks=[AuditHook(), MetricsHook()])
```
Async hook methods are fan-out with error isolation. `finalize_content` is a pipeline: each hook receives the previous hook's output.
### Example: post-process final content
```python
from nanobot.agent import AgentHook
class Censor(AgentHook):
def finalize_content(self, context, content):
return content.replace("secret", "***") if content else content
```
## Full Example
```python
import asyncio
import time
from nanobot import Nanobot
from nanobot.agent import AgentHook, AgentHookContext
class TimingHook(AgentHook):
def __init__(self) -> None:
super().__init__()
self._started_at = 0.0
async def before_iteration(self, context: AgentHookContext) -> None:
self._started_at = time.perf_counter()
async def after_iteration(self, context: AgentHookContext) -> None:
elapsed_ms = (time.perf_counter() - self._started_at) * 1000
print(f"[timing] iteration {context.iteration} took {elapsed_ms:.1f}ms")
async def main() -> None:
bot = Nanobot.from_config(workspace="/my/project")
result = await bot.run(
"Explain the main function",
session_key="sdk:demo",
hooks=[TimingHook()],
)
print(result.content)
asyncio.run(main())
```

## Install
> [!IMPORTANT]
> This README may describe features that are available first in the latest source code.
> If you want the newest features and experiments, install from source.
> If you want the most stable day-to-day experience, install from PyPI or with `uv`.
**Install from source** (latest features, experimental changes may land here first; recommended for development)
```bash
git clone https://github.com/HKUDS/nanobot.git
cd nanobot
pip install -e .
```
**Install with [uv](https://github.com/astral-sh/uv)** (stable release, fast)
```bash
uv tool install nanobot-ai
```
**Install from PyPI** (stable release)
```bash
pip install nanobot-ai
```
### Update to latest version
**PyPI / pip**
```bash
pip install -U nanobot-ai
nanobot --version
```
**uv**
```bash
uv tool upgrade nanobot-ai
nanobot --version
```
**Using WhatsApp?** Rebuild the local bridge after upgrading:
```bash
rm -rf ~/.nanobot/bridge
nanobot channels login whatsapp
```
## Quick Start
> [!TIP]
> Set your API key in `~/.nanobot/config.json`.
> Get API keys: [OpenRouter](https://openrouter.ai/keys) (Global)
>
> For other LLM providers, please see [`configuration.md`](./configuration.md).
>
> For web search capability setup, please see the web-search section in [`configuration.md`](./configuration.md#web-search).
**1. Initialize**
```bash
nanobot onboard
```
Use `nanobot onboard --wizard` if you want the interactive setup wizard.
**2. Configure** (`~/.nanobot/config.json`)
Configure these **two parts** in your config (other options have defaults).
*Set your API key* (e.g. OpenRouter, recommended for global users):
```json
{
"providers": {
"openrouter": {
"apiKey": "sk-or-v1-xxx"
}
}
}
```
*Set your model* (optionally pin a provider — defaults to auto-detection):
```json
{
"agents": {
"defaults": {
"model": "anthropic/claude-opus-4-5",
"provider": "openrouter"
}
}
}
```
**3. Chat**
```bash
nanobot agent
```
That's it! You have a working AI agent in 2 minutes.

"""Hatch build hook that bundles the webui (Vite) into nanobot/web/dist.
Triggered automatically by `python -m build` (and any other hatch-driven build)
so published wheels and sdists ship a fresh webui without requiring developers
to remember `cd webui && bun run build` beforehand.
Behaviour:
- Skips for editable installs (`pip install -e .`). Editable mode is for Python
development; webui contributors use `cd webui && bun run dev` (Vite HMR) and
do not need a packaged `dist/`.
- No-op when `webui/package.json` is absent (e.g. installing from an sdist that
already contains a prebuilt `nanobot/web/dist/`).
- Skips when `NANOBOT_SKIP_WEBUI_BUILD=1` is set.
- Skips when `nanobot/web/dist/index.html` already exists, unless
`NANOBOT_FORCE_WEBUI_BUILD=1` is set.
- Uses `bun` when available, otherwise falls back to `npm`. The chosen tool
performs `install` followed by `run build`.

objectives (especially **idempotent**, compaction-safe goals). Load that skill
from the skills listing (path shown there) before composing ``long_task.goal`` text.
``long_task`` registers an objective on the session (JSON-serializable metadata).
Active objectives are mirrored each turn into the Runtime Context block (see
``nanobot.session.goal_state.goal_state_runtime_lines``) so compaction cannot hide them.
Work proceeds in ordinary agent turns (same runner, compaction as configured).
Call ``complete_goal`` when the sustained objective should stop being tracked:
finished successfully, or cancelled / superseded / redirected—in every case the recap should match reality.
