check-docs

A command that compares the saved Claude Code documentation version with the installed version and the newest version available through npm, a JavaScript package registry.

In plain words
What is it for?
Use it to check documentation freshness and decide whether to update Claude Code or fetch the reference pages again.
Why use it?
It shows whether the local reference pages are outdated or have never been downloaded, so version differences do not go unnoticed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

check-docs 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 yesterday.

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.

Report

  • Docs version vs installed version: if they differ → ⚠️ Docs were fetched on an older install, suggest running /claude-craft:update-docs
  • Installed version vs latest available: if they differ → ⚠️ Claude Code itself has an update available, suggest updating Claude Code first (claude update), then running /claude-craft:update-docs
  • All three match → ✅ Everything is up to date
  • Docs version is empty or status is "seeded" → ❌ Docs have never been fetched, suggest running /claude-craft:update-docs

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.
