AI Skill Grader

Put AI Skill Grader where skills run.

The website checks a skill or repo before you try it. Installed in Claude Code or Codex, the grader brings that check into your coding session.

Choose your agent Grade a skill or repo

The site grades links. The tool brings reports to your workflow.

You should not have to remember to copy every skill into a website. Install the grader once, and it lets you check skills from the place where you already use them.

1

Your agent starts with skills available.

2

AI Skill Grader reads the skill's public files.

3

You see what it can touch and what to check first.

4

In Claude Code, a manipulative skill is blocked before it runs.

Install options

Pick the agent you use most and run its command below. It installs with npx, backs up your config, and never asks for your credentials. Read the installer first.

Automatic check

Claude Code

Checks each skill the first time Claude Code uses it, and blocks it on the spot if its instructions try to manipulate or exfiltrate. The installer sets it up and installs it into Claude Code for you; open a new session and it is on.

Report on request

Codex

Adds AI Skill Grader inside Codex so you can ask for the full report on any skill, or paste a GitHub link, without leaving your task.

First time running such commands? Show me the step-by-step
  1. Open your terminal. You already run Codex and Claude Code in a terminal, so you are in the right place. Check that Node is installed: type node -v and press Enter. A version number (like v20.11.0) means you are ready; if it says "command not found," install Node from nodejs.org first.
  2. Run the command for your agent from the box above and press Enter. It sets itself up and installs into your agent for you, listing the files it changes and backing each one up first.
  3. Open a new session. Open a new Claude Code session, or restart Codex, and the grader is on. In Claude Code it reads each new skill and blocks manipulative ones automatically; in Codex, ask for a report on any skill whenever you want one.

Every command can be run again. npx ai-skill-grader uninstall removes the hooks and report skill; delete ~/.ai-skill-grader to remove the local copy.

Questions

Which coding agents does AI Skill Grader work with?

Claude Code checks every skill automatically the first time it is used and blocks manipulative ones on the spot. Codex adds a grader you can ask for a full report on any skill. On any other tool, grade skills on the website.

Is AI Skill Grader free?

Yes. The read inside Claude Code, the report inside Codex, and grading any public skill or repo on the website are all free.

What does AI Skill Grader check?

Two things: what the skill can touch, and whether anything was flagged before you rely on it. The installed grader uses local checks for the in-session read. Full website reports may also use cached or background review, but we do not connect your accounts or run production workflows.

Does it work with Cursor, Cline, or Windsurf?

Not yet. If you would like AI Skill Grader available inside Cursor, Cline, or Windsurf, email us at reports@aiskillgrader.com. The more people ask, the sooner we add it. You can grade any skill on the website in the meantime.

Not ready to install?

Use the web grader first. Paste a public GitHub repo or direct SKILL.md file and see the preview on the page.
