- container/.dockerignore (new): exclude agent-runner/node_modules and
agent-runner/dist so COPY agent-runner/ ./ doesn't clobber the
pnpm-installed node_modules with host directories. Under npm's flat
layout this was forgiving; under pnpm's symlink layout it's a hard
conflict (overlay2 cannot copy onto a symlink target).
- setup/{groups,service}.ts: execSync('pnpm run build') not npm.
- setup/index.ts: usage string.
- scripts/*.ts: usage comments + seed-discord final log.
- .claude/settings.json: permission allowlist entries.
- .claude/skills/{add-whatsapp-v2,add-dashboard}/SKILL.md: docs.
- container/skills/{frontend-engineer,vercel-cli,self-customize}/SKILL.md:
agent-facing docs still told the container agent to run npm.

# Self-Customization
|
|
|
|
You can modify your own environment. Different kinds of changes have different workflows.
|
|
|
|
## Decision Tree
|
|
|
|
**What needs to change?**
|
|
|
|
- **Your CLAUDE.md or files in your workspace** → Edit directly, no approval needed. Your workspace (`/workspace/agent/`) is persisted on the host.
|
|
- **System package (apt) or global npm package** → `install_packages` → `request_rebuild`. Requires admin approval.
|
|
- **MCP server** → `add_mcp_server` → `request_rebuild`. No approval needed, but rebuild required to apply.
|
|
- **Your source code or Dockerfile** → Delegate to a builder agent via `create_agent` (see below).
|
|
- **A new specialist capability** → `create_agent` to spin up a dedicated agent for it.
|
|
|
|
## Workflow: Code Changes via Builder Agent
|
|
|
|
For anything that requires editing source files (your own code, Dockerfile, etc.), **do not edit directly** — delegate to a builder agent. This gives the user a reviewable boundary and keeps your main session focused.
|
|
|
|
1. Describe what you need changed in concrete terms (files, behavior, acceptance criteria)
|
|
2. Call `create_agent({ name: "Builder", instructions: "<builder prompt>" })` — the returned agent group ID is your builder
|
|
3. Call `send_to_agent({ agentGroupId, text: "<task description with specific files and changes>" })`
|
|
4. The builder works in its own container, makes the changes, and reports back
|
|
5. You review the builder's summary, confirm with the user, then call `request_rebuild` if the changes require it
|
|
|
|
### Builder Agent Instructions (use as CLAUDE.md when creating)
|
|
|
|
```
|
|
You are a builder agent. Your job is to make precise, minimal code changes to NanoClaw source files when the main agent requests it.
|
|
|
|
## Rules
|
|
|
|
- **Minimal scope.** Only change what was requested. Do not refactor surrounding code, "improve" unrelated files, or add features not asked for.
|
|
- **Diff size limits.** Reject any change that exceeds 200 new lines or 150 modified lines in a single task. If the change is larger, push back and ask for it to be split into smaller tasks.
|
|
- **Read before writing.** Always read the target file fully before editing. Understand the existing patterns.
|
|
- **Test if possible.** If there are relevant tests, run them after your change.
|
|
- **Report back.** When done, use send_to_agent to tell the requesting agent: (a) what files you changed, (b) a summary of the changes, (c) any follow-up needed (rebuild, tests, migrations).
|
|
- **No silent failures.** If you can't complete the task, explain why — don't produce partial work without flagging it.
|
|
|
|
## Safety
|
|
|
|
- Never edit files outside the requested scope
|
|
- Never commit or push anything
|
|
- Never modify secrets, credentials, or .env files
|
|
- If a change would break existing tests, stop and report
|
|
```
|
|
|
|
## Diff Size Limits — Why
|
|
|
|
A 50-line focused change is reviewable. A 500-line sweep is not. Hard limits force the agent to decompose work into reviewable chunks, which:
|
|
|
|
- Makes human approval meaningful (you can actually read 150 lines)
|
|
- Catches runaway edits early (if the first task hits the limit, the scope was wrong)
|
|
- Forces clear acceptance criteria per task
|
|
|
|
The limits are **per builder task**, not per session. A 500-line feature is fine as 4 sequential builder tasks of ~125 lines each, each with its own scope.
|
|
|
|
## Example: Adding a New MCP Tool to Yourself
|
|
|
|
User: "Can you add a tool for reading RSS feeds?"
|
|
|
|
1. Check [mcp.so](https://mcp.so) for an existing RSS MCP server
|
|
2. If one exists → `add_mcp_server({ name: "rss", command: "npx", args: ["some-rss-mcp"] })` → `request_rebuild` → done
|
|
3. If nothing suitable exists → delegate to a builder agent:
|
|
- `create_agent({ name: "RSS Tool Builder", instructions: "<builder prompt from above>" })`
|
|
- `send_to_agent({ agentGroupId, text: "Add an MCP tool 'read_rss' to container/agent-runner/src/mcp-tools/. It should fetch an RSS URL and return the latest N items. Register it in mcp-tools/index.ts. Target: <200 new lines." })`
|
|
- Wait for builder's report
|
|
- `request_rebuild` if needed
|
|
|
|
## Example: Installing a System Tool
|
|
|
|
User: "Can you transcribe audio?"
|
|
|
|
1. Check what's available — `which ffmpeg` (likely not installed in base image)
|
|
2. Decide approach: `@xenova/transformers` (npm, workspace-local) or `whisper.cpp` (apt + compile)
|
|
3. For persistent system tool: `install_packages({ apt: ["ffmpeg"], npm: ["@xenova/transformers"], reason: "Audio transcription for voice messages" })`
|
|
4. Wait for admin approval
|
|
5. `request_rebuild({ reason: "Apply audio transcription packages" })`
|
|
6. Wait for admin approval
|
|
7. Test the new capability once the container restarts
|
|
|
|
## When NOT to Self-Customize
|
|
|
|
- **The change is for a one-off task** — just do it in your workspace, don't modify the container
|
|
- **The request is ambiguous** — ask the user what they actually need before spinning up builders or requesting installs
|
|
- **You don't know if it will work** — prototype in your workspace first (`pnpm install` in `/workspace/agent/`), then promote to container-level install if it proves useful
