README

skillassay — measure what your AI coding agent loads before you type

**A static analyzer for AI coding-agent context, and an Agent Skill your agent can run itself.** It measures the always-on context-window cost of `CLAUDE.md`, `AGENTS.md`, `GEMINI.md` and Agent Skills, then reports skills that will not load, redundant instructions, stale path references, duplicate skill names and instruction conflicts — with a citation and a token count on every finding.

Use it two ways:

As a CLI — npx skillassay .
As an Agent Skill — drop it into .agents/skills/ and ask your agent to audit the repo in plain language. It costs 98 always-on tokens.

Works with **Claude Code**, **Codex**, **Cursor** and **Gemini CLI**. Runs offline. No API key.

**This is a research project.** It is published so the method and the numbers can be checked, not as a supported product. Provided **as is, without warranties or conditions of any kind** — see [Disclaimer](#disclaimer).

Install

No install, no API key, no config. Requires Node.js ≥ 20.11.

Install as an Agent Skill

The package ships an Agent Skill in `.agents/skills/skillassay/` — the cross-client location that **Claude Code, Codex and Gemini CLI all read**, so one file serves every harness:

npm i -D skillassay
mkdir -p .agents/skills
cp -r node_modules/skillassay/.agents/skills/skillassay .agents/skills/

Then just ask, in whichever agent you use:

*"Audit this repo's context cost."* *"Will my new skill actually load?"* *"What's in my always-on context and what can I delete?"*

If you would rather scope it to one client, the same directory works under `.claude/skills/`, `.codex/skills/` or `.gemini/skills/`. `.agents/skills/` is preferred because it is read by all of them.

It costs **98 always-
