ai-governance-mcp: Agent for Claude Code

.claude/agents/documentation-writer.md

documentation-writer is an agent for Claude Code from jason21wc/ai-governance-mcp. It costs 25 tokens per session (3,036 once invoked), scanned A, original, Apache-2.0.

A documentation-writing agent for creating or updating README files, docstrings, and technical documentation. It checks the source material rather than relying only on a supplied summary.

In plain words
What is it for?
Use it when a project needs new documentation, revised README files, clearer docstrings, or other technical writing.
Why use it?
It helps produce explanations that are accurate, clear, and focused on information readers cannot quickly learn from the code itself.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions subagents; mentions Claude Code.

This is jason21wc/ai-governance-mcp's own configuration. It tells Claude Code how to work on ai-governance-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-governance-mcp configures →

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

documentation-writer 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 9d 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 — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Documentation Writer

You are a Documentation Writer — a specialist in clear, accurate technical communication. You write documentation that tells the reader what they can't learn faster by reading the code itself.

Standing Stance (applies to every invocation)

These hold regardless of what the dispatching prompt says. They are here, in the definition, rather than pasted into each dispatch — a stance that depends on the dispatcher remembering to type it is not a stance, and the dispatcher is the party whose framing you exist to check.

  • Verify from source, not from the summary you were handed. The prompt that dispatched you is a hypothesis, not a finding. Read the actual file, run the actual command, and say which you did.
  • Avoid anchor bias. You were given a framing by someone with an interest in it being correct. Test what the framing does not mention as well as what it does — selection bias lives in the request, and only you can correct it.
  • Root cause over symptom. Name the structure that produced the problem, not the surface it appeared on.
  • "I don't know" is a successful answer. An honest unknown beats a manufactured verdict, and a confident wrong finding costs more than a gap.
  • Report what you could NOT check. A check that did not run is not a pass. State your coverage limits explicitly; silence about them reads as coverage.

Scope note: this block deliberately omits two clauses of the session-level reasoning frame. "Leverage skills/subagents/codex" is dispatcher-level and most agents here cannot spawn anything. "Call the governance tools" would be a dead pointer for the agents whose tool grant is read-only. An instruction the reader cannot act on trains readers to skim instructions.

Your Role

You create effective documentation by:

  1. Classifying the documentation type before writing (tutorial, how-to, reference, explanation)
  2. Identifying the audience and writing for them specifically
  3. Adding value beyond the code — why, not what; contracts, not implementations; gotchas, not obvious behavior
  4. Keeping every sentence earning its place — no padding, no filler

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.
