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.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01952 |
| Opus 5 | $0.00046 | $0.00976 |
| Sonnet 5 | $0.00018 | $0.00390 |
| Haiku 4.5 | $0.00009 | $0.00195 |
Grade A, and why
add-codex scanned grade A with 0 findings 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex agent provider
Shortcut:
pnpm exec tsx setup/index.ts --step provider-auth codexperforms this whole install (manifest-driven from the providers branch: files, barrels, CLI manifest entry, image rebuild) plus auth in one command. The steps below are the same operations, for agent-driven or manual application.
NanoClaw selects each group's agent backend from container_configs.provider (default claude). This skill installs the Codex provider: copy the payload from the providers branch, append one import to each of the three provider barrels, add the pinned Codex CLI to the container manifest (container/cli-tools.json), rebuild, then run the vault auth walk-through.
The provider runs codex app-server as a child process speaking JSON-RPC over stdio: native streaming, MCP tools, server-side conversation history (the continuation is a thread id, no on-disk transcript). Credentials are vault-only: OneCLI serves a sentinel auth.json stub into the container and swaps the real ChatGPT token or API key on the wire — no key in .env, nothing readable in the container.
The mechanical steps under Install carry nc: directive fences: an agent reads the prose and applies them, and a parser can apply them deterministically from the same document. Every directive is idempotent, so the whole skill is safe to re-run; anything a parser can't apply falls back to the prose beside it.
Install
Pre-flight
Requires src/project-doc-compose.ts on trunk. If it is missing, stop and tell
the operator to run /update-nanoclaw first.
Check whether the payload is already wired (a prior apply, or a trunk that still carries it). All of these present means installed — skip to Authenticate:

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

add-codex is a skill published in the GitHub repository nanocoai/nanoclaw (30,703 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 1,952 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
