 nanobot's memory is built on a simple belief: memory should feel alive, but it should not feel chaotic.
 
 Good memory is not a pile of notes. It is a quiet system of attention. It notices what is worth keeping, lets go of what no longer needs the spotlight, and turns lived experience into something calm, durable, and useful.

+# 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())
+```

 - 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).
-

-  | <-- {"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.

-> - `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`).

-# 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 |
-| `/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 |
-| `/help` | Show available in-chat commands |
-
-## 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, the agent executes them and delivers results to your most recently active chat channel.
-
-**Setup:** edit `~/.nanobot/workspace/HEARTBEAT.md` (created automatically by `nanobot onboard`):
-
-```markdown
-## Periodic 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.
-
-> **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.

-## Environment Variables for Secrets
-
-Instead of storing secrets directly in `config.json`, you can use `${VAR_NAME}` references that are resolved from environment variables at startup:
-
-```json
-{
-  "channels": {
-    "telegram": { "token": "${TELEGRAM_TOKEN}" },
-    "email": {
-      "imapPassword": "${IMAP_PASSWORD}",

-  },
-  "providers": {
-    "groq": { "apiKey": "${GROQ_API_KEY}" }
-  }
-}
-```
-
-For **systemd** deployments, use `EnvironmentFile=` in the service unit to load variables from a file that only the deploying user can read:
-
-```ini
-# /etc/systemd/system/nanobot.service (excerpt)
-[Service]
-EnvironmentFile=/home/youruser/nanobot_secrets.env
-User=nanobot
-ExecStart=...

-
-```bash
-# /home/youruser/nanobot_secrets.env (mode 600, owned by youruser)
-TELEGRAM_TOKEN=your-token-here
-IMAP_PASSWORD=your-password-here
-```
-
-## Providers
-
-> [!TIP]
-> - **Voice transcription**: Voice messages (Telegram, WhatsApp) are automatically transcribed using Whisper. By default Groq is used (free tier). Set `"transcriptionProvider": "openai"` under `channels` to use OpenAI Whisper instead, and optionally set `"transcriptionLanguage": "en"` (or another ISO-639-1 code) for more accurate transcription. The API key is picked from the matching provider config.
-> - **MiniMax Coding Plan**: Exclusive discount links for the nanobot community: [Overseas](https://platform.minimax.io/subscribe/coding-plan?code=9txpdXw04g&source=link) · [Mainland China](https://platform.minimaxi.com/subscribe/token-plan?code=GILTJpMTqZ&source=link)
-> - **MiniMax (Mainland China)**: If your API key is from MiniMax's mainland China platform (minimaxi.com), set `"apiBase": "https://api.minimaxi.com/v1"` in your minimax provider config.
-> - **MiniMax thinking mode**: Use `providers.minimaxAnthropic` when you want `reasoningEffort` / thinking mode. MiniMax exposes that capability through its Anthropic-compatible endpoint, so nanobot keeps it as a separate provider instead of guessing MiniMax-specific thinking parameters on the generic OpenAI-compatible `minimax` endpoint. It uses the same `MINIMAX_API_KEY`. Default Anthropic-compatible base URL: `https://api.minimax.io/anthropic`; for mainland China use `https://api.minimaxi.com/anthropic`.
-> - **VolcEngine / BytePlus Coding Plan**: Use dedicated providers `volcengineCodingPlan` or `byteplusCodingPlan` instead of the pay-per-use `volcengine` / `byteplus` providers.
-> - **Zhipu Coding Plan**: If you're on Zhipu's coding plan, set `"apiBase": "https://open.bigmodel.cn/api/coding/paas/v4"` in your zhipu provider config.
-> - **Alibaba Cloud BaiLian**: If you're using Alibaba Cloud BaiLian's OpenAI-compatible endpoint, set `"apiBase": "https://dashscope.aliyuncs.com/compatible-mode/v1"` in your dashscope provider config.
-> - **Step Fun (Mainland China)**: If your API key is from Step Fun's mainland China platform (stepfun.com), set `"apiBase": "https://api.stepfun.com/v1"` in your stepfun provider config.

-}
-```
-
-> For local servers that don't require authentication, set `apiKey` to `null`.
->
-> `custom` is the right choice for providers that expose an OpenAI-compatible **chat completions** API. It does **not** force third-party endpoints onto the OpenAI/Azure **Responses API**.
->
-> If your proxy or gateway is specifically Responses-API-compatible, use the `azure_openai` provider shape instead and point `apiBase` at that endpoint:
->
-> ```json
-> {
->   "providers": {
->     "azure_openai": {
->       "apiKey": "your-api-key",
->       "apiBase": "https://api.your-provider.com",

-<summary><b>Adding a New Provider (Developer Guide)</b></summary>
-
-nanobot uses a **Provider Registry** (`nanobot/providers/registry.py`) as the single source of truth.
-Adding a new provider only takes **2 steps** — no if-elif chains to touch.
-
-**Step 1.** Add a `ProviderSpec` entry to `PROVIDERS` in `nanobot/providers/registry.py`:
-
-```python
-ProviderSpec(
-    name="myprovider",                   # config field name
-    keywords=("myprovider", "mymodel"),  # model-name keywords for auto-matching
-    env_key="MYPROVIDER_API_KEY",        # env var name
-    display_name="My Provider",          # shown in `nanobot status`
-    default_api_base="https://api.myprovider.com/v1",  # OpenAI-compatible endpoint
-)
-```
-
-**Step 2.** Add a field to `ProvidersConfig` in `nanobot/config/schema.py`:
-
-```python
-class ProvidersConfig(BaseModel):
-    ...
-    myprovider: ProviderConfig = ProviderConfig()
-```
-
-That's it! Environment variables, model routing, config matching, and `nanobot status` display will all work automatically.
-
-**Common `ProviderSpec` options:**
-
-| Field | Description | Example |
-|-------|-------------|---------|
-| `default_api_base` | OpenAI-compatible base URL | `"https://api.deepseek.com"` |
-| `env_extras` | Additional env vars to set | `(("ZHIPUAI_API_KEY", "{api_key}"),)` |
-| `model_overrides` | Per-model parameter overrides | `(("kimi-k2.5", {"temperature": 1.0}), ("kimi-k2.6", {"temperature": 1.0}),)` |
-| `is_gateway` | Can route any model (like OpenRouter) | `True` |
-| `detect_by_key_prefix` | Detect gateway by API key prefix | `"sk-or-"` |
-| `detect_by_base_keyword` | Detect gateway by API base URL | `"openrouter"` |
-| `strip_model_prefix` | Strip provider prefix before sending to gateway | `True` (for AiHubMix) |
-| `supports_max_completion_tokens` | Use `max_completion_tokens` instead of `max_tokens`; required for providers that reject both being set simultaneously (e.g. VolcEngine) | `True` |
-
-</details>
-
-## Channel Settings
-
-Global settings that apply to all channels. Configure under the `channels` section in `~/.nanobot/config.json`:
-
-```json
-{
-  "channels": {
-    "sendProgress": true,
-    "sendToolHints": false,
-    "sendMaxRetries": 3,
-    "transcriptionProvider": "groq",
-    "transcriptionLanguage": null,
-    "telegram": { ... }
-  }
-}
-```
-
-| Setting | Default | Description |
-|---------|---------|-------------|
-| `sendProgress` | `true` | Stream agent's text progress to the channel |
-| `sendToolHints` | `false` | Stream tool-call hints (e.g. `read_file("…")`) |
-| `sendMaxRetries` | `3` | Max delivery attempts per outbound message, including the initial send (0-10 configured, minimum 1 actual attempt) |
-| `transcriptionProvider` | `"groq"` | Voice transcription backend: `"groq"` (free tier, default) or `"openai"`. API key is auto-resolved from the matching provider config. |
-| `transcriptionLanguage` | `null` | Optional ISO-639-1 language hint for audio transcription, e.g. `"en"`, `"ko"`, `"ja"`. |
-
-### Retry Behavior
-
-Retry is intentionally simple.
-
-When a channel `send()` raises, nanobot retries at the channel-manager layer. By default, `channels.sendMaxRetries` is `3`, and that count includes the initial send.
-
-- **Attempt 1**: Send immediately
-- **Attempt 2**: Retry after `1s`
-- **Attempt 3**: Retry after `2s`
-- **Higher retry budgets**: Backoff continues as `1s`, `2s`, `4s`, then stays capped at `4s`
-- **Transient failures**: Network hiccups and temporary API limits often recover on the next attempt
-- **Permanent failures**: Invalid tokens, revoked access, or banned channels will exhaust the retry budget and fail cleanly
-
-> [!NOTE]
-> This design is deliberate: channel implementations should raise on delivery failure, and the channel manager owns the shared retry policy.
->
-> Some channels may still apply small API-specific retries internally. For example, Telegram separately retries timeout and flood-control errors before surfacing a final failure to the manager.
->
-> If a channel is completely unreachable, nanobot cannot notify the user through that same channel. Watch logs for `Failed to send to {channel} after N attempts` to spot persistent delivery failures.
-
-## Web Search
-
-> [!TIP]
-> Use `proxy` in `tools.web` to route all web requests (search + fetch) through a proxy:
-> ```json
-> { "tools": { "web": { "proxy": "http://127.0.0.1:7890" } } }
-> ```
-
-nanobot supports multiple web search providers. Configure in `~/.nanobot/config.json` under `tools.web.search`.
-
-By default, web tools are enabled and web search uses `duckduckgo`, so search works out of the box without an API key.
-
-If you want to disable all built-in web tools entirely, set `tools.web.enable` to `false`. This removes both `web_search` and `web_fetch` from the tool list sent to the LLM.
-
-If you need to allow trusted private ranges such as Tailscale / CGNAT addresses, you can explicitly exempt them from SSRF blocking with `tools.ssrfWhitelist`:
-
-```json
-{
-  "tools": {
-    "ssrfWhitelist": ["100.64.0.0/10"]
-  }
-}
-```
-
-| Provider | Config fields | Env var fallback | Free |

-```
-
-**SearXNG** (self-hosted, no API key needed):

-        "provider": "searxng",
-        "baseUrl": "https://searx.example"

-
-### `tools.web.search`
-

-
-## MCP (Model Context Protocol)
-
-> [!TIP]
-> The config format is compatible with Claude Desktop / Cursor. You can copy MCP server configs directly from any MCP server's README.
-
-nanobot supports [MCP](https://modelcontextprotocol.io/) — connect external tool servers and use them as native agent tools.
-
-Add MCP servers to your `config.json`:
-
-```json
-{
-  "tools": {
-    "mcpServers": {
-      "filesystem": {
-        "command": "npx",
-        "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"]
-      },
-      "my-remote-mcp": {
-        "url": "https://example.com/mcp/",
-        "headers": {
-          "Authorization": "Bearer xxxxx"
-        }
-      }
-    }
-  }
-}
-```
-
-Two transport modes are supported:
-
-| Mode | Config | Example |
-|------|--------|---------|
-| **Stdio** | `command` + `args` | Local process via `npx` / `uvx` |
-| **HTTP** | `url` + `headers` (optional) | Remote endpoint (`https://mcp.example.com/sse`) |
-
-Use `toolTimeout` to override the default 30s per-call timeout for slow servers:
-
-```json
-{
-  "tools": {
-    "mcpServers": {
-      "my-slow-server": {
-        "url": "https://example.com/mcp/",
-        "toolTimeout": 120
-      }
-    }
-  }
-}
-```
-
-Use `enabledTools` to register only a subset of tools from an MCP server:
-
-```json
-{
-  "tools": {
-    "mcpServers": {
-      "filesystem": {
-        "command": "npx",
-        "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"],
-        "enabledTools": ["read_file", "mcp_filesystem_write_file"]
-      }
-    }
-  }
-}
-```
-
-`enabledTools` accepts either the raw MCP tool name (for example `read_file`) or the wrapped nanobot tool name (for example `mcp_filesystem_write_file`).
-
-- Omit `enabledTools`, or set it to `["*"]`, to register all tools.
-- Set `enabledTools` to `[]` to register no tools from that server.
-- Set `enabledTools` to a non-empty list of names to register only that subset.
-
-MCP tools are automatically discovered and registered on startup. The LLM can use them alongside built-in tools — no extra configuration needed.
-
-
-
-
-## Security
-
-> [!TIP]
-> For production deployments, set `"restrictToWorkspace": true` and `"tools.exec.sandbox": "bwrap"` in your config to sandbox the agent.
-> In `v0.1.4.post3` and earlier, an empty `allowFrom` allowed all senders. Since `v0.1.4.post4`, empty `allowFrom` denies all access by default. To allow all senders, set `"allowFrom": ["*"]`.
-
-| Option | Default | Description |
-|--------|---------|-------------|
-| `tools.restrictToWorkspace` | `false` | When `true`, restricts **all** agent tools (shell, file read/write/edit, list) to the workspace directory. Prevents path traversal and out-of-scope access. |
-| `tools.exec.sandbox` | `""` | Sandbox backend for shell commands. Set to `"bwrap"` to wrap exec calls in a [bubblewrap](https://github.com/containers/bubblewrap) sandbox — the process can only see the workspace (read-write) and media directory (read-only); config files and API keys are hidden. Automatically enables `restrictToWorkspace` for file tools. **Linux only** — requires `bwrap` installed (`apt install bubblewrap`; pre-installed in the Docker image). Not available on macOS or Windows (bwrap depends on Linux kernel namespaces). |
-| `tools.exec.enable` | `true` | When `false`, the shell `exec` tool is not registered at all. Use this to completely disable shell command execution. |
-| `tools.exec.pathAppend` | `""` | Extra directories to append to `PATH` when running shell commands (e.g. `/usr/sbin` for `ufw`). |
-| `channels.*.allowFrom` | `[]` (deny all) | Whitelist of user IDs. Empty denies all; use `["*"]` to allow everyone. |
-
-**Docker security**: The official Docker image runs as a non-root user (`nanobot`, UID 1000) with bubblewrap pre-installed. When using `docker-compose.yml`, the container drops all Linux capabilities except `SYS_ADMIN` (required for bwrap's namespace isolation).
-
-
-## Auto Compact
-
-When a user is idle for longer than a configured threshold, nanobot **proactively** compresses the older part of the session context into a summary while keeping a recent legal suffix of live messages. This reduces token cost and first-token latency when the user returns — instead of re-processing a long stale context with an expired KV cache, the model receives a compact summary, the most recent live context, and fresh input.
-
-```json
-{
-  "agents": {
-    "defaults": {
-      "idleCompactAfterMinutes": 15
-    }
-  }
-}
-```
-
-| Option | Default | Description |
-|--------|---------|-------------|
-| `agents.defaults.idleCompactAfterMinutes` | `0` (disabled) | Minutes of idle time before auto-compaction starts. Set to `0` to disable. Recommended: `15` — close to a typical LLM KV cache expiry window, so stale sessions get compacted before the user returns. |
-
-`sessionTtlMinutes` remains accepted as a legacy alias for backward compatibility, but `idleCompactAfterMinutes` is the preferred config key going forward.
-
-How it works:
-1. **Idle detection**: On each idle tick (~1 s), checks all sessions for expiration.
-2. **Background compaction**: Idle sessions summarize the older live prefix via LLM and keep the most recent legal suffix (currently 8 messages).
-3. **Summary injection**: When the user returns, the summary is injected as runtime context (one-shot, not persisted) alongside the retained recent suffix.
-4. **Restart-safe resume**: The summary is also mirrored into session metadata so it can still be recovered after a process restart.
-
-> [!NOTE]
-> Mental model: "summarize older context, keep the freshest live turns, **and overwrite the session file with the compact form.**" It is not a full `session.clear()`, but it is a write — not a soft cursor move.
->
-> Concretely, auto compact rewrites `sessions/<key>.jsonl` in place: older messages (including their structured `tool_calls` / `tool_call_id` / `reasoning_content`) are replaced by just the retained recent suffix (currently 8 messages), while the archived prefix is preserved only as a plain-text summary appended to `memory/history.jsonl` (or a `[RAW] ...` flattened dump if LLM summarization fails). The original structured JSON of those turns is no longer recoverable from the session file.
->
-> This differs from the **token-driven soft consolidation** that fires when a prompt exceeds the context budget: that path only advances an internal `last_consolidated` cursor and leaves the session file untouched, so the raw tool-call trail stays on disk and can still be replayed or audited. If you rely on that trail for debugging or auditing, leave `idleCompactAfterMinutes` at the default `0` and let only the token-driven path run.
-
-## Timezone
-
-Time is context. Context should be precise.
-
-By default, nanobot uses `UTC` for runtime time context. If you want the agent to think in your local time, set `agents.defaults.timezone` to a valid [IANA timezone name](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones):
-
-```json
-{
-  "agents": {
-    "defaults": {
-      "timezone": "Asia/Shanghai"
-    }
-  }
-}
-```
-
-This affects runtime time strings shown to the model, such as runtime context and heartbeat prompts. It also becomes the default timezone for cron schedules when a cron expression omits `tz`, and for one-shot `at` times when the ISO datetime has no explicit offset.
-
-Common examples: `UTC`, `America/New_York`, `America/Los_Angeles`, `Europe/London`, `Europe/Berlin`, `Asia/Tokyo`, `Asia/Shanghai`, `Asia/Singapore`, `Australia/Sydney`.
-
-> Need another timezone? Browse the full [IANA Time Zone Database](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
-
-## Unified Session
-
-By default, each channel × chat ID combination gets its own session. If you use nanobot across multiple channels (e.g. Telegram + Discord + CLI) and want them to share the same conversation, enable `unifiedSession`:
-
-```json
-{
-  "agents": {
-    "defaults": {
-      "unifiedSession": true
-    }
-  }
-}
-```
-
-When enabled, all incoming messages — regardless of which channel they arrive on — are routed into a single shared session. Switching from Telegram to Discord (or any other channel) continues the same conversation seamlessly.
-
-| Behavior | `false` (default) | `true` |
-|----------|-------------------|--------|
-| Session key | `channel:chat_id` | `unified:default` |
-| Cross-channel continuity | No | Yes |
-| `/new` clears | Current channel session | Shared session |
-| `/stop` finds tasks | By channel session | By shared session |
-| Existing `session_key_override` (e.g. Telegram thread) | Respected | Still respected — not overwritten |
-
-> This is designed for single-user, multi-device setups. It is **off by default** — existing users see zero behavior change.
-
-## Disabled Skills
-
-nanobot ships with built-in skills, and your workspace can also define custom skills under `skills/`. If you want to hide specific skills from the agent, set `agents.defaults.disabledSkills` to a list of skill directory names:
-
-```json
-{
-  "agents": {
-    "defaults": {
-      "disabledSkills": ["github", "weather"]
-    }
-  }
-}
-```
-
-Disabled skills are excluded from the main agent's skill summary, from always-on skill injection, and from subagent skill summaries. This is useful when some bundled skills are unnecessary for your deployment or should not be exposed to end users.
-
-| Option | Default | Description |
-|--------|---------|-------------|
-| `agents.defaults.disabledSkills` | `[]` | List of skill directory names to exclude from loading. Applies to both built-in skills and workspace skills. |

-## 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 user `nanobot` (UID 1000). 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.

-
-**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

-# 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

-# 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 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())

-## Core Principles
-
-- Solve by doing, not by describing what I would do.
-- Keep responses short unless depth is asked for.
-- Say what I know, flag what I don't, and never fake confidence.
-- Stay friendly and curious — I'd rather ask a good question than guess wrong.
-- Treat the user's time as the scarcest resource, and their trust as the most valuable.
-
-## Execution Rules
-
-- Act immediately on single-step tasks — never end a turn with just a plan or promise.
-- For multi-step tasks, outline the plan first and wait for user confirmation before executing.
-- Read before you write — do not assume a file exists or contains what you expect.
-- If a tool call fails, diagnose the error and retry with a different approach before reporting failure.
-- When information is missing, look it up with tools first. Only ask the user when tools cannot answer.
-- After multi-step changes, verify the result (re-read the file, run the test, check the output).
