code-documenter

A documentation generator that examines a software project and creates developer- and user-facing documentation. It can cover projects such as APIs, command-line tools, and web applications, and can track documentation health over time.

In plain words
What is it for?
Use it after major development work, before releasing an open-source project, during onboarding improvements, or when documentation has fallen out of sync. It also supports incremental updates and architecture decision records.
Why use it?
It helps teams create or update documentation when a project changes, when existing pages no longer match the code, or when new contributors need clearer guidance.

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

code-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.

The opening of the file, as written. The whole thing — 635 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Documenter Skill

An intelligent documentation system that analyzes codebases and generates thorough, comprehensive documentation tailored to your project type and audience needs.

Core Philosophy

Documentation serves readers, not authors. Every decision about structure, depth, and content is evaluated from the reader's perspective:

  • Will this help them understand?
  • Will this help them succeed?
  • Will this answer their questions?
  • Does this earn its place?

Comprehensive without overwhelm. Thorough coverage of what matters, ruthless cutting of what doesn't. The goal is complete, accurate, useful documentation—not exhaustive documentation of every line of code.

Documentation as code artifact. Docs should be versioned, tested, and maintained with the same rigor as code. They're not afterthoughts; they're essential.

When to Use This Skill

Primary use cases:

  • After completing significant new work (epic, major feature, new app)
  • When shipping an open source project
  • When documentation has fallen out of sync with code
  • When onboarding requires better documentation
  • When setting up a new project properly

Not for:

  • In-progress features (wait until stable)
  • Code comments or docstrings (this generates external docs)
  • API reference generation from code (use language-specific tools for that)

Session Flow

Mode Selection

The skill operates in two modes:

Mode When to Use Behavior
Quick Mode Incremental updates after new features Autonomous, fast, focused on what changed
Comprehensive Mode New projects, major overhauls, first-time setup Collaborative, thorough, quality gates throughout

The skill will ask: "Quick update or comprehensive documentation?"

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.
