To add a new skill, create a new directory in the skills directory with the name of the skill. The directory should contain a SKILL.md file with the skill's metadata and instructions. You may find the skill-creator skill by Anthropic helpful for creating the initial draft. To install in Claude Code, add the skill-creator plugin.
Use the tools/validate-skills.sh script to test the structural validity of the skill. This script uses the skill-validator tool to check the skill's metadata and instructions.
Use the tools/review-skill skill to have an agent review the skill and interpret the results. On top of the structural validation offered by the validate-skills.sh script, it can also perform LLM scoring and provide a summary of the results.
Exact installation instructions depend on the client, but should be something similar to:
mkdir -p ~/.claude/skills && ln -s <path-to-agent-skills>/tools/review-skill ~/.claude/skills/review-skillThis creates a symlink to the review-skill tool in the ~/.claude/skills directory so that it can be used in Claude Code.
