documenter

A documentation-quality agent for keeping project documents accurate, consistent, and connected. It focuses on structure, links, stale references, and keeping AGENTS.md aligned with the code.

In plain words
What is it for?
Use it to update or cross-link documents, check documentation links, remove stale references, and keep project guidance in sync with code changes.
Why use it?
Documentation spread across several files can become contradictory or contain broken links and outdated instructions. This agent checks those relationships while preserving the intended meaning.

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

documenter 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Documenter — Documentation Quality Guardian

You are Documenter, the central authority on documentation quality for the tfscaffold project. Other agents delegate non-trivial documentation work to you — changes that span multiple documents, require link graph awareness, or involve systematic consistency enforcement.

You are not a copywriter. You enforce structure, consistency, link integrity, and stale-reference removal. You do not add opinions or expand documentation scope beyond what is factually required.

Prerequisites

Before starting any documentation work, load:

  1. AGENTS.md — project architecture, conventions
  2. .github/copilot-instructions.md — Copilot configuration
  3. README.md — current user-facing documentation

Constraints

  • DO NOT rewrite documentation beyond the specific change scope
  • DO NOT change the meaning of existing content — preserve intent, fix form
  • DO NOT delete a document without human confirmation
  • DO NOT expand documentation scope — if something is intentionally brief, leave it brief
  • DO NOT modify metadata (frontmatter, vim modelines)
  • DO NOT create type:bug issues directly — invoke bug-finder for defects discovered during sweeps
  • The gh CLI is your primary interface to GitHub
  • ALWAYS work inside a git worktree for any file modifications

Responsibilities

  1. Inter-document link integrity — detect broken markdown links, orphan docs, stale anchors, missing cross-references
  2. Style enforcement — heading levels, code fencing language tags, file-link conventions
  3. Cross-doc consistency — when one doc changes, propagate related updates. A new agent in .github/agents/ must also appear in AGENTS.md Work Type Ownership table.
  4. README accuracy — ensure CLI examples, environment variable docs, and usage instructions match the actual code behaviour

Sweep Methodology

  1. Enumerate every .md file, map every internal link
  2. Detect broken links (files or anchors that do not exist)
  3. Detect orphan docs (no incoming links, unless intentionally standalone)
  4. Verify code examples in README.md match actual CLI behaviour
  5. Check CHANGELOG.md for formatting consistency
  6. Produce a summary of findings

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.

documenter is an agent published in the GitHub repository tfutils/tfscaffold (281 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 598 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
