update-skills

update-skills is a skill for Claude Code from nanocoai/nanoclaw. It costs 45 tokens per session (711 once invoked), scanned A, original, MIT.

A refresh tool for updating installed NanoClaw channel and provider code from its registry branches.

In plain words
What is it for?
Use it after updating NanoClaw or when channel and provider code may be stale. It can refresh all installed integrations or a named subset, and reports a structured result.
Why use it?
It prevents installed integrations from remaining out of date after NanoClaw or registry changes, while avoiding credential and configuration changes.

Written for Claude Code: installed under .claude/. Also seen: mentions OpenCode.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./container/build.sh pull.

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.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

  • high Privilege Escalation · line 73
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 A, and why

update-skills 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 11d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update installed skills

Refresh the code carried by installed channel and provider skills. This does not re-run credential setup, change .env, alter wiring, or restart services.

Run from the NanoClaw project root. Use ordinary conversation for any choice; do not depend on a provider-specific question or skill-invocation tool.

1. Preflight and selection

Require a clean working tree:

git status --porcelain

If it is dirty, stop. Never mix a refresh with unrelated changes.

The default is every installed channel/provider. If the user asked for a subset, pass its comma-separated names. Otherwise use all:

pnpm exec tsx scripts/update-skills.ts --skills all
# Example subset: --skills slack,opencode

The helper detects installed skills from the real channel/provider barrels. It resolves each registry branch by checking configured remotes, so a fork whose origin is the user's repo and whose official source is upstream works without special handling. NANOCLAW_REGISTRY_REMOTE=<name> is an explicit override and is validated before use.

2. Treat the JSON result as a gate

The command prints nanoclaw-skill-refresh/v1-shaped JSON fields with one result per selected skill and exits nonzero unless every selected skill was fully refreshed.

  • Continue only when success is true and every status is refreshed.
  • A missing skill, missing structured apply contract, unresolved input, agent fallback, fetch error, or dependency error is blocking.
  • Never record a failed skill and continue toward an upgrade completion stamp.
  • Preserve the full report in the update summary.

The refresh engine overwrites skill-owned registry files and advances exact dependency/CLI-manifest pins. It skips prompts, operator walkthroughs, .env writes, wiring, restarts, and ordinary build/test directives.

3. Validate the composed checkout

After a successful refresh:

pnpm run build
pnpm test

If files under container/agent-runner/src/ changed, also run:

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.
