What it does

Document is an agent skill from hashgraph-online/awesome-codex-plugins. Documentation generator for public APIs, functions, and modules. Use when exports, signatures, or new modules are added or changed.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Technical documentation. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Detect what changed
Write docs
Don't over-document

What it can do on your machine

Read from SKILL.md and the folder at commit 16b4156. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Document loads about 745 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 308 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~745

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: document
description: Documentation generator for public APIs, functions, and modules. Use when exports, signatures, or new modules are added or changed.

Document — Auto-Documentation

When to Trigger

New public function, class, or API endpoint
Function signature changed (params added/removed)
Module purpose unclear from code alone
User explicitly asks for documentation

Process

1. Detect what changed

New exports? → Add JSDoc/docstring
Changed params? → Update existing docs
New file? → Add module-level doc comment

Why: Undocumented changes are the most common source of onboarding friction. Catching every diff ensures no public surface is left without context.

2. Write docs

Follow the project's existing doc style. If none exists:

TypeScript/JavaScript:

typescript

/**
 * Brief description of what this does.
 *
 * @param name - Description of parameter
 * @returns Description of return value
 * @throws ErrorType - When this happens
 *
 * @example
 * const result = myFunction("input");
 */

Python:

python

def my_function(name: str) -> str:
    """Brief description.

    Args:
        name: Description of parameter.

    Returns:
        Description of return value.

    Raises:
        ValueError: When this happens.
    """

Why: Consistent doc style across the project reduces cognitive load for every reader. Inlining examples prevents the "how do I call this?" round-trip.

3. Don't over-document

Skip obvious getters/setters
Skip internal/private helpers unless complex
Code should be self-documenting first, comments second

Why: Noise docs train readers to ignore all comments. Document only where the code cannot speak for itself.

Anti-Rationalization

Excuse	Rebuttal	What to do instead
"The code is self-documenting"	Good naming helps readers, but doesn't explain intent, constraints, or edge cases.	Document the why, the constraints, and the non-obvious.
"I'll document it later"	Later never comes. If it's worth exporting, it's worth documenting now.	Document as you write. Updating is cheaper than reconstructing intent.
"Docs go stale anyway"	Stale docs are better than no docs. They at least signal intent. Keep them in sync with code changes.	Put docs near code (JSDoc/docstring). They update with the code.

Evidence Required

Before claiming documentation is done, show ALL applicable:

Every new public function/class has a doc comment (show one example)
Changed signatures have updated docs (show the diff)
@param / @returns / @throws present for non-trivial functions
At least one @example for complex APIs

"I added docs" without showing them = not documented.

Red Flags

Comments that restate the code: // increment i → i++
Outdated comments that contradict the code
Missing docs on public API that others will call
