README Maintainer

README Maintainer is a skill for Claude Code from CDCgov/cdc-open-viz. It costs 16 tokens per session (2,329 once invoked), scanned A, original, Apache-2.0.

A checklist and maintenance workflow for keeping a project's README.md accurate and aligned with its actual files, scripts, setup steps, and generated directories.

In plain words
What is it for?
Use it to inspect a repository, correct documentation drift, verify usage instructions, and replace README placeholders when the repository provides enough evidence.
Why use it?
It helps prevent users from following outdated commands, paths, prerequisites, or examples and flags details that cannot be inferred safely.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: agent in frontmatter; installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is {Architecture - description or pointer to separate documentation under \[ARCHITECTURE.md](./docs/ARCHITECTURE.md) if lengthy}.

Good fit Use it to inspect a repository, correct documentation drift, verify usage instructions, and replace README placeholders when the repository provides enough evidence.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

README Maintainer 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 9d 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 — 293 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Maintain README.md with an accuracy-first pass.

Requirements:

  • Inspect the current workspace before editing.
  • Prefer minimal changes that correct drift between the README and checked-in files.
  • Verify script names, paths, prerequisites, usage examples, and any documented generated or runtime directories.
  • Replace unresolved placeholders (identified by brackets {}) in README metadata when the intended value can be inferred from the repository context; otherwise call out the uncertainty explicitly with a TODO.
  • When filling {Keywords}, use only exact terms from the approved taxonomy provided in the following JSON that has the terms grouped by top-level categories:

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.
