document

A code-documentation command that adds explanations to functions, classes, complex logic, and project README files. It can also improve TypeScript type annotations and follow the project's existing documentation style.

In plain words
What is it for?
Use it to create docstrings, inline comments, installation and usage instructions, API references, configuration notes, examples, and error documentation.
Why use it?
It removes the need to write routine code explanations from scratch and helps keep documentation consistent with the code.

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

document 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

Generate documentation for: $ARGUMENTS

Include:

  1. Function/Class Docstrings

    • Description of purpose
    • @param for each parameter with type and description
    • @returns with type and description
    • @throws for possible errors
    • @example with usage example
  2. Inline Comments

    • Explain complex logic
    • Note any non-obvious decisions
    • Mark TODOs or FIXMEs
  3. README Sections (if applicable)

    • Installation instructions
    • Usage examples
    • API reference
    • Configuration options
  4. Type Annotations

    • Add or improve TypeScript types
    • Document complex types with JSDoc

Format according to the project's existing documentation style. If no style exists, use JSDoc for JavaScript/TypeScript.

Changes

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.
