repo-docs

repo-docs is a skill for Claude Code, Codex from V-Songbird/slag. It costs 170 tokens per session (1,051 once invoked), scanned A, original, MIT.

A documentation maintenance guide that compares a project's written instructions and development files with its current behavior and documentation rules.

In plain words
What is it for?
Use it to audit or clean up README files, development instructions, and related documentation, or to adopt a shared documentation policy in a project.
Why use it?
It helps find outdated, duplicated, or unclear documentation before it misleads developers. It can report issues or propose approved fixes, depending on the request.

Skill for Claude CodeCodex

Written for Claude Code and Codex: argument-hint in frontmatter, but also agents/openai.yaml present. Also seen: mentions Claude Code; mentions Codex; $skill-name invocation.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

repo-docs 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 4d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo docs

Make the maintained documentation agree with what the project actually does, make its development instructions usable by each intended host, and give a project one documentation policy to follow.

Argument: $ARGUMENTS. If the host leaves it literal, read the request instead. audit, a review request, an explicit no-edit instruction, or the command alone with no argument and no request beside it means report only: nothing is written in the project, and a report is saved only as the reconciliation's step 4 allows. fix, or an explicit reconciliation or cleanup request in the owner's words, authorizes ordinary in-scope documentation fixes. Resolve an ambiguous request as an audit, and end an audit by naming fix as the way to apply its ordinary fixes. maintain runs the maintenance step first and edits nothing until the owner approves a group of its proposals. adopt edits nothing until the owner approves the files it shows. readme, or a request about one README, works on that README alone. A request to write one page for people authorizes writing that page and works on it alone; a request to review one reports on that page alone. A path narrows the pass to that area plus its incoming references; state that boundary.

On Claude Code invoke /anneal:repo-docs; on Codex use $repo-docs; on Antigravity use /repo-docs. Find the plugin files through ${CLAUDE_PLUGIN_ROOT} on Claude Code, or resolve ../../ from this file on other hosts. Resolve target paths against the project root, never the installed plugin directory.

On Antigravity, give every command the project root the person named as its working directory, the Cwd of run_command. Without it, commands can run in Antigravity's own scratch directory instead of the project. When the person named no project root, ask for it before running anything.

Modes

Every mode reads the Invariants section of the documentation contract first, and treats the project's own applicable instructions as its documentation policy.

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.
