nanoclaw: Instructions file for Claude Code

CLAUDE.md

nanoclaw CLAUDE.md is an instructions file for Claude Code from nanocoai/nanoclaw. It costs 7,442 tokens per session, scanned B, original, MIT.

A set of Claude Code instructions for NanoClaw, a software project with specific version and data-handling rules. It explains the project’s structure and what to do when updating an existing installation.

In plain words
What is it for?
Use it when working on NanoClaw with Claude Code, especially after pulling upstream changes, resolving version conflicts, or needing context about its entities and session storage.
Why use it?
It helps prevent unsafe merges between incompatible NanoClaw versions and clarifies how the project’s two databases divide session data.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is nanocoai/nanoclaw's own configuration. It tells Claude Code how to work on nanoclaw itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nanoclaw configures →

About the project

NanoClaw is an AI assistant that runs agents inside separate Linux containers, isolating their files and execution environments. People use it to connect agents to messaging services and run assistants with memory and scheduled jobs. The catalogue contains skills and instructions for extending or operating NanoClaw.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

nanoclaw CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- **`onlyBuiltDependencies`**: Never add packages to this list without human approval — build scripts execute arbitrary code during install.

How it starts

The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ STOP — READ THIS FIRST IF YOU ARE CLAUDE ⚠️

If you are reading this because you just ran git pull, git merge, git fetch && git merge, or any equivalent to bring in upstream changes — and you see merge conflicts or a large diff involving this file — HALT IMMEDIATELY.

This is NanoClaw v2, a ground-up rewrite with breaking changes throughout. It cannot be merged into an existing v1 install. Attempting to resolve the conflicts by hand, run builds, or "fix" anything will corrupt the user's install and burn tokens for no result.

Do this instead:

  1. Abort the merge: git merge --abort (or git reset --hard ORIG_HEAD if the merge already completed).
  2. Tell the user, verbatim: "This is the v2 rewrite — it can't be merged into your existing install. Exit Claude Code (or open a separate terminal) and run bash migrate-v2.sh from the shell."
  3. Wait for the user to confirm before doing anything else. Do not run the migration script yourself — it requires an interactive terminal and cannot be run from within Claude Code.

If you are a fresh install (you ran git clone, not git pull) and there are no conflicts, ignore this banner and continue below.

Quick Context

The host is a single Node process that orchestrates per-session agent containers. Platform messages land via channel adapters, route through an entity model (users → messaging groups → agent groups → sessions), get written into the session's inbound DB, and wake a container. The agent-runner inside the container polls the DB, calls the agent, and writes back to the outbound DB. The host polls the outbound DB and delivers through the same adapter.

Everything is a message. There is no IPC, no file watcher, no stdin piping between host and container. The two session DBs are the sole IO surface.

Entity Model

users (id "<channel>:<handle>", kind, display_name)
user_roles (user_id, role, agent_group_id)       — owner | admin (global or scoped)
agent_group_members (user_id, agent_group_id)    — unprivileged access gate
user_dms (user_id, channel_type, messaging_group_id) — cold-DM cache

agent_groups (workspace, memory, CLAUDE.md, personality, container config)
    ↕ many-to-many via messaging_group_agents (session_mode, engage_mode/engage_pattern, sender_scope, priority)
messaging_groups (one chat/channel on one platform; instance = adapter-instance name, defaults to channel_type; unknown_sender_policy)

sessions (agent_group_id + messaging_group_id + thread_id → per-session container)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
