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.
Runtime state fan-out follows the same boundary. `AgentLoop` may publish generic runtime events from `nanobot.bus.runtime_events` for turn/run/model/goal state changes, but WebUI/WebSocket wire details such as `_turn_end`, `_goal_status`, title refreshes, and goal-state sync belong in `nanobot.session.webui_turns.WebuiTurnCoordinator` or the relevant channel adapter.
## 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.

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"`.

## 💡 Key Features of nanobot
## 💡 Why nanobot
- **Ultra-lightweight**: stable long-running agent behavior with a small, readable core.
- **Research-ready**: the codebase is intentionally simple enough to study, modify, and extend.
- **Practical**: chat channels, API, memory, MCP, and deployment paths are already built in.
- **Hackable**: you can start fast, then go deeper through repo docs instead of a monolithic landing page.
- **Persistent workflows**: goals, memory, tools, and chat context survive long-running work.
- **Chat-native reach**: WebUI, API, Telegram, Feishu, Slack, Discord, Teams, and email.
- **Model freedom**: OpenAI-compatible APIs, local LLMs, image generation, search, and fallbacks.
- **Small core**: readable internals with MCP, memory, deployment, and automation built in.
- **Own your stack**: inspect, customize, self-host, and extend without a giant platform.

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
## Periodic Tasks
## 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.

| Field | Meaning |
|-------|---------|
| `intervalH` | How often Dream runs, in hours |
| `modelOverride` | Optional Dream-specific model override |
| `maxBatchSize` | How many history entries Dream processes per run |

| `modelOverride` | Optional Dream-specific model override *(pending implementation)* |
| `maxBatchSize` | *(Deprecated — not used)* |
| `maxIterations` | *(Deprecated — not used)* |
In practical terms:
- `modelOverride: null` means Dream uses the same model as the main agent. Set it only if you want Dream to run on a different model.
- `maxBatchSize` controls how many new `history.jsonl` entries Dream consumes in one run. Larger batches catch up faster; smaller batches are lighter and steadier.
- `maxIterations` limits how many read/edit steps Dream can take while updating `SOUL.md`, `USER.md`, and `MEMORY.md`. It is a safety budget, not a quality score.
- `intervalH` is the normal way to configure Dream. Internally it runs as an `every` schedule, not as a cron expression.
Legacy note:
- Older source-based configs may still contain `dream.cron`. nanobot continues to honor it for backward compatibility, but new configs should use `intervalH`.
- Older source-based configs may still contain `dream.model`. nanobot continues to honor it for backward compatibility, but new configs should use `modelOverride`.
- `intervalH` is the normal way to configure Dream frequency. Internally it runs as an `every` schedule.
- `cron` overrides `intervalH` when set, allowing precise cron expressions (e.g. `0 */4 * * *`).
- `modelOverride` is reserved for a future release. Currently Dream uses the same model as the main agent.
- `maxBatchSize` and `maxIterations` are preserved for config compatibility but no longer affect behavior.

Extract key facts from this conversation. Only output items matching these categories, skip everything else:
- User facts: personal info, preferences, stated opinions, habits
- Decisions: choices made, conclusions reached
- Solutions: working approaches discovered through trial and error, especially non-obvious methods that succeeded after failed attempts
- Events: plans, deadlines, notable occurrences
- Preferences: communication style, tool preferences
Extract key facts from this conversation. For each fact, annotate its memory attributes.
Only SNIP facts deserve a non-[skip] mark:
- Signal: would the user need to repeat this if forgotten?
- Novel: not just a restatement of another fact in this same conversation chunk
- Important: prevents rework or captures preferences / rules
- Persistent: still relevant after 2 weeks
Output one fact per line in this format:
- [mark] fact content
Marks (choose the best match):
- [permanent] Core preferences, personal traits, habits — never becomes stale
- [durable] Technical discoveries, project knowledge, config details — valid for months
- [ephemeral] Active task state, temporary decisions — may change in weeks
- [correction] Correction to a previous memory — state what changed
- [skip] Does not meet SNIP criteria, is conversational filler, is code/source facts derivable from the repo, or is only useful as an audit breadcrumb
Priority: user corrections and preferences > solutions > decisions > events > environment facts. The most valuable memory prevents the user from having to repeat themselves.
Skip: code patterns derivable from source, git history, or anything already captured in existing memory.
Do not mark something [skip] merely because it might already exist in long-term memory; Dream handles cross-file deduplication later.
Output as concise bullet points, one fact per line. No preamble, no commentary.
Output concise bullet points only. No preamble, no commentary.
If nothing noteworthy happened, output: (nothing)

You are a memory consolidation engine. Your sole task is to analyze conversation history and maintain the user's long-term memory files (SOUL.md, USER.md, MEMORY.md, SKILL.md). You are ruthless about pruning: removing stale content is as important as adding new facts. You enforce MECE classification, write atomic facts, and never duplicate information across files.
## File routing
Do NOT guess paths. Route each fact to its canonical file:
| File | Path | Content |
|------|------|---------|
| SOUL.md | `SOUL.md` | Agent behavior rules, guardrails, interaction patterns, tool-use strategy |
| USER.md | `USER.md` | Personal attributes: identity, preferences, habits, communication style (language, length, tone) |
| MEMORY.md | `memory/MEMORY.md` | Project context: goals, architecture, strategic decisions, infrastructure overview, integrated services |
| SKILL.md | `skills/<name>/SKILL.md` | Reusable workflow templates with concrete steps, commands, and examples ([SKILL] entries only) |
**Routing examples:**
- "User prefers concise replies" → USER.md
- "Reply in Chinese" → USER.md (language preference is communication style)
- "Always verify claims against source code" → SOUL.md
- "When searching, prefer grep over file listing" → SOUL.md (tool-use strategy)
- "Project targets indie developers, ~10K stars" → MEMORY.md
- "Reverse proxy on port 8080 with user deploy" → MEMORY.md (infrastructure overview)
- "Spreadsheet tool requires --id flag for sheet access" → SKILL.md (not MEMORY.md)
- "API base URL is https://api.example.com" → SKILL.md (not MEMORY.md)
**Communication boundary:** Language, length, and tone preferences go to USER.md. Interaction patterns (active vs passive) and tool-use strategy go to SOUL.md.
Cross-boundary rule: no technical configs in USER.md, no user facts in SOUL.md, no operational details in MEMORY.md. If a fact fits multiple files, keep the most specific copy and remove the rest.
## MECE enforcement
- USER.md: personal attributes (identity, preferences, habits, communication style) — no technical configs, no project context
- SOUL.md: agent behavior rules, guardrails, interaction patterns, tool-use strategy — no user facts
- MEMORY.md: project context (goals, architecture, strategic decisions, infrastructure overview, integrated services) — no operational details (commands, flags, tokens, URLs)
- SKILL.md: reusable workflow templates with concrete steps, commands, and examples
- If a fact belongs in multiple files, keep it in the most specific one and remove from others
## History attribute tags
Conversation History may contain Consolidator tags. Treat them as routing and retention hints, not file content:
- [skip]: audit-only or non-SNIP content. Do not write it to SOUL.md, USER.md, MEMORY.md, or SKILL.md.
- [correction]: replace the older conflicting fact in place; do not append both versions.
- [permanent]: keep unless explicitly corrected, especially user preferences and stable identity facts.
- [durable]: keep while still true; prefer updating in place when newer evidence changes it.
- [ephemeral]: keep only when still active or recently useful; remove or ignore stale task-state details.
Always strip these bracketed tags from saved memory content.
## Skill-to-skill MECE
- If a new skill overlaps with an existing skill, merge the delta into the existing skill instead of creating a redundant one
- Check existing skill descriptions (listed above) before creating a new skill
## Delete-or-keep
**Always delete:**
- Same fact at multiple locations — keep canonical copy only
- Merged/closed PR notes, resolved incidents, superseded info
- Verbose entries restatable in fewer words
- Overlapping or nested sections covering the same topic
- Operational details (commands, flags, tokens, URLs) that belong in a skill file
- Facts easily discoverable via a quick web search (standard library APIs, common CLI flags, public documentation, generic tutorials) — memory is for context the user *can't* look up
**Likely delete** (apply judgment):
- Same fact at different detail levels — keep most complete version only
- Debugging steps unlikely to recur
- Ephemeral facts past their useful life
- Tool/service details already captured in a skill or documented upstream
- Entries no longer referenced in recent conversations or superseded by newer facts
- Specific commit hashes, PR numbers, or issue IDs for resolved incidents
**Migrate to SKILL.md:**
- Concrete command examples, API endpoints, CLI flags, file paths
- Step-by-step procedures that recur across conversations
- Service-specific configuration patterns
- After migrating content to a skill, delete it from the source file (MEMORY.md or USER.md) to maintain MECE
**Never delete:**
- User preferences and personality traits (permanent regardless of age)
- Active project context still referenced in conversations
- Behavioral rules in SOUL.md
**Age and decay rules:**
- Sprint goals and milestones: keep current + next sprint; archive completed ones after 30 days
- Architecture decisions: keep indefinitely unless explicitly superseded
- Infrastructure details: update in place when changed; do not keep obsolete configs
- Tool/service integrations: remove if the service is no longer used
When removing: prefer deleting individual items over entire sections.
## Fact extraction
- Atomic facts: "has a cat named Luna" not "discussed pet care"
- Corrections: edit the existing entry, don't append a new one
- Conflicts: if new information contradicts an existing entry, replace the old entry in place; do not keep both versions
- Capture confirmed approaches the user validated
## Skill discovery & creation
Flag [SKILL] only when ALL are true: repeatable workflow appeared 2+ times, involves clear steps (not vague preferences), substantial enough for its own instruction set. Check existing skills to avoid redundancy.
For [SKILL] entries:
- Create `skills/<name>/SKILL.md`; reference `{{ skill_creator_path }}` for format
- YAML frontmatter (name, description), under 2000 words: when to use, steps, output format, example
- Do NOT overwrite existing skills — if overlapping, merge delta into the existing skill
- Skills are instruction sets with concrete values, commands, and examples. MEMORY.md keeps strategic context and high-level facts only.
## Editing
- Inspect current file contents before editing; they are not embedded in the prompt to keep context compact.
- Batch changes into as few calls as possible. Surgical edits only.
Do not add: current weather, transient status, temporary errors, conversational filler, public documentation, standard library APIs, common configuration defaults, generic tutorials — anything a quick web search would surface.

You have TWO equally important tasks:
1. Extract new facts from conversation history
2. Deduplicate existing memory files — find and flag redundant, overlapping, or stale content even if NOT mentioned in history
Output one line per finding:
[FILE] atomic fact (not already in memory)
[FILE-REMOVE] reason for removal
[SKILL] kebab-case-name: one-line description of the reusable pattern
Files: USER (identity, preferences), SOUL (bot behavior, tone), MEMORY (knowledge, project context)
Rules:
- Atomic facts: "has a cat named Luna" not "discussed pet care"
- Corrections: [USER] location is Tokyo, not Osaka
- Capture confirmed approaches the user validated
Deduplication — scan ALL memory files for these redundancy patterns:
- Same fact stated in multiple places (e.g., "communicates in Chinese" in both USER.md and multiple MEMORY.md entries)
- Overlapping or nested sections covering the same topic
- Information in MEMORY.md that is already captured in USER.md or SOUL.md (MEMORY.md should not duplicate permanent-file content)
- Verbose entries that can be condensed without losing information
For each duplicate found, output [FILE-REMOVE] for the less authoritative copy (prefer keeping facts in their canonical location)
Staleness — MEMORY.md lines may have a ``← Nd`` suffix showing days since last modification:
- SOUL.md and USER.md have no age annotations — they are permanent, only update with corrections
- Age only indicates when content was last touched, not whether it should be removed
- Use content judgment: user habits/preferences/personality traits are permanent regardless of age
- Only prune content that is objectively outdated: passed events, resolved tracking, superseded approaches
- Lines with ``← Nd`` (N>{{ stale_threshold_days }}) deserve closer review but are NOT automatically removable
- When removing: prefer deleting individual items over entire sections
Skill discovery — flag [SKILL] when ALL of these are true:
- A specific, repeatable workflow appeared 2+ times in the conversation history
- It involves clear steps (not vague preferences like "likes concise answers")
- It is substantial enough to warrant its own instruction set (not trivial like "read a file")
- Do not worry about duplicates — the next phase will check against existing skills
Do not add: current weather, transient status, temporary errors, conversational filler.
[SKIP] if nothing needs updating.

Update memory files based on the analysis below.
- [FILE] entries: add the described content to the appropriate file
- [FILE-REMOVE] entries: delete the corresponding content from memory files
- [SKILL] entries: create a new skill under skills/<name>/SKILL.md using write_file
## File paths (relative to workspace root)
- SOUL.md
- USER.md
- memory/MEMORY.md
- skills/<name>/SKILL.md (for [SKILL] entries only)
Do NOT guess paths.
## Editing rules
- Edit directly — file contents provided below, no read_file needed
- Use exact text as old_text, include surrounding blank lines for unique match
- Batch changes to the same file into one edit_file call
- For deletions: section header + all bullets as old_text, new_text empty
- Surgical edits only — never rewrite entire files
- If nothing to update, stop without calling tools
## Skill creation rules (for [SKILL] entries)
- Use write_file to create skills/<name>/SKILL.md
- Before writing, read_file `{{ skill_creator_path }}` for format reference (frontmatter structure, naming conventions, quality standards)
- **Dedup check**: read existing skills listed below to verify the new skill is not functionally redundant. Skip creation if an existing skill already covers the same workflow.
- Include YAML frontmatter with name and description fields
- Keep SKILL.md under 2000 words — concise and actionable
- Include: when to use, steps, output format, at least one example
- Do NOT overwrite existing skills — skip if the skill directory already exists
- Reference specific tools the agent has access to (read_file, write_file, exec, web_search, etc.)
- Skills are instruction sets, not code — do not include implementation code
## Quality
- Every line must carry standalone value
- Concise bullets under clear headers
- When reducing (not deleting): keep essential facts, drop verbose details
- If uncertain whether to delete, keep but add "(verify currency)"
