# Claude Skill Validator

> Paste your SKILL.md and get an instant Agent Skills spec-compliance report. Free, no signup, validation runs entirely in your browser.

## What it does

- Parses the YAML frontmatter of a pasted SKILL.md (name, description, allowed-tools, compatibility, license, metadata and other fields).
- Runs ~25 checks across frontmatter, name rules, description quality, allowed-tools, compatibility, license and body structure.
- Each failed check reports severity (error / warning / suggestion), a plain-English explanation, the exact line number, and a suggested fix.
- Computes a 0-100 compliance score so you can see progress as you fix issues.
- Compares the skill `name` field against the directory name you type, catching rename mistakes.
- Ships with two one-click samples: a valid SKILL.md and a deliberately broken one, to see every check in action.
- "Copy as Markdown" exports the full report for pasting into a chat, docs or a pull request.

## Who it is for

Developers writing Agent Skills (the SKILL.md format used by Claude Code and other coding agents) who want to catch spec violations before shipping.

## Pricing

Free. No account, no signup. Validation runs locally in the browser; nothing you paste is uploaded to a server.
