update-docs

A documentation-update skill synchronizes comments and supporting documentation with uncommitted code changes.

In plain words
What is it for?
It is for finding modified files, adding or updating language-appropriate documentation blocks, and updating related files in a `docs` folder.
Why use it?
It reduces the chance that changed functions or project documentation explain old behavior.

Made for: Claude Code, Codex.

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-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 2d 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.

What it actually says

Documentation Update Task

Update documentation for all uncommitted code changes.

Steps

  1. Run git diff --name-only to identify modified files
  2. For each code file:
    • Detect existing documentation style (see references/doc-patterns.md)
    • Find new/modified functions, classes, methods
    • Add or update documentation blocks
  3. If /docs folder exists:
    • Check if changed code has corresponding docs
    • Update affected documentation files
    • Do NOT modify README.md, CHANGELOG.md, LICENSE
  4. Report all changes made

Reference Documents

For documentation patterns by language, read:

  • references/doc-patterns.md - Format examples for each stack

Documentation Style Matching

Always match the existing documentation style in the file:

  • If PHPDoc exists, use PHPDoc
  • If JSDoc exists, use JSDoc
  • If no existing docs, detect from file extension

Output Requirements

Return a report listing:

  • Files modified
  • Docblocks added/updated
  • Summary counts
Files

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.

Changes

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.
