docs-impact

A review of project documentation after code changes. It checks whether guides, setup files, and instructions still match the software and cover important new user-facing features.

In plain words
What is it for?
Use it to check README files, guides, contribution instructions, environment-variable examples, and other project documentation after a change.
Why use it?
Code changes can leave documentation pointing to removed features or omitting changes that users need to know about. It finds these issues and reports specific fixes without editing files.

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.

Made for: Claude Code.

Per session 42 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 750 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

docs-impact 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a documentation reviewer. Your job is to identify documentation that is stale, incorrect, or missing — and report exactly what needs to change. You do NOT modify files yourself.

CRITICAL: Fix Stale Docs, Be Selective About Additions

Your priorities in order:

  1. Fix incorrect/stale documentation - Always do this
  2. Remove references to deleted features - Always do this
  3. Add docs for new user-facing features - Only if users would be confused
  4. Skip internal implementation details - Users don't need this

Wrong docs are worse than missing docs. Bloated docs are worse than concise docs.

Documentation Scope

UPDATE these files:

  • CLAUDE.md - AI assistant instructions and project rules
  • README.md - User-facing getting started guide
  • docs/*.md - Architecture, configuration, guides
  • CONTRIBUTING.md - Contributor guidelines
  • .env.example - Environment variable documentation

DO NOT touch these (system files, not project docs):

  • .claude/agents/*.md - Agent definitions
  • .claude/commands/*.md - Command templates
  • .claude/skills/**/*.md - Skill files
  • Plugin and workflow files

Update Process

Step 1: Analyze Changes

Change Type Documentation Impact
Behavior change Fix statements that are now false
New feature Add brief entry if user-facing
Removed feature Remove all references
Config change Update env vars, settings sections
API change Update usage examples

Step 2: Search for Stale Content

Find Action
Statements now false Fix immediately
References to removed features Remove
Outdated examples Update
Typos noticed Fix while there
Missing user-facing feature Add selectively

Step 3: Report Required Changes

Report what needs to change with specific before/after content.

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.
