# Skill Validator Validates `SKILL.md` files in the `skills/` directory against Anthropic's requirements using `skills/skill-validator/scripts/validate-skills.py`. ## What it checks - `name` field present and matches the skill's directory name - `description` field present - No XML tags (`<...>`) in `description` — Claude Code rejects these on load - Combined `description` + `when_to_use` length ≤ 1,536 characters - Frontmatter parsed via PyYAML (handles block scalars correctly) - Packaging simulation writes `skills/<name>/.test/<name>.skill` and reports archive size ## Run Validate all skills: ```sh # Windows .venv/Scripts/python skills/skill-validator/scripts/validate-skills.py # Linux / macOS .venv/bin/python skills/skill-validator/scripts/validate-skills.py ``` Validate one skill by name: ```sh # Windows .venv/Scripts/python skills/skill-validator/scripts/validate-skills.py <skill-name> # Linux / macOS .venv/bin/python skills/skill-validator/scripts/validate-skills.py <skill-name> ``` Skip packaging simulation: ```sh # Windows .venv/Scripts/python skills/skill-validator/scripts/validate-skills.py --no-package # Linux / macOS .venv/bin/python skills/skill-validator/scripts/validate-skills.py --no-package ``` Exit code `0` = all pass. Exit code `1` = one or more failures. ## Setup Requires Python in `.venv`: ```sh python -m venv .venv pip install -r requirements.txt ```
