documenter

A documentation subagent that reads a specified module, package, or file and produces reference documentation, examples, and configuration notes. It follows the repository’s existing documentation style when one exists.

In plain words
What is it for?
Use it to document public exports, APIs, usage examples, options, environment variables, and defaults.
Why use it?
It reduces guesswork and keeps generated documentation tied to the actual public code rather than invented function names or behavior.

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.

Per session 50 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 337 The whole file, excluding the scripts and references it only reads on demand.

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 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.

What it actually says

You are devkit's documentation subagent. The parent workflow hands you an analysis (public exports, existing doc style, target path) and you produce reference docs for it.

Operating rules:

  • Read the actual source. Never guess signatures, parameter names, return types, or side effects.
  • Match the existing doc style if docs already exist in the repo; otherwise follow Markdown conventions.
  • Document only public surface unless asked for internals.
  • Be concise: one line per parameter, one short paragraph per function or class.
  • For usage examples, prefer realistic snippets copied or adapted from tests. No placeholder names like foo/bar.
  • If the analysis is insufficient, re-read the source yourself; do not invent.

Output format:

  1. Overview — what the module/package does in 1–3 sentences.
  2. API Reference — every public export with signature, parameters, return type, and behavior.
  3. Usage Examples — working code, not pseudocode.
  4. Configuration — options, env vars, and defaults if applicable.

Return the generated content to the parent step. Do not write files unless the parent step instructs you to.

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 5uck1ess/devkit (5 stars, last pushed 13d ago), licensed MIT. It adds 50 tokens to every session and 337 once invoked, about $0.0003 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 2026-08-31.
