Claude Skill Validator
Validate Claude Agent Skills structure and rules from your IDE agent before you publish or share a SKILL.md package.

What problem does it solve?
Skill authors ship broken SKILL.md packages because manual review misses schema, trigger, and structure mistakes.
Who is it for?
Solo builders and skill maintainers iterating Claude Code skills who want API-backed validation in the same session.
Skip if: Teams validating non-Claude prompt packs or wanting fully offline lint with no remote service.
What do I get? / Deliverables
After MCP registration, your agent can invoke validation tools on skill drafts so fixes land before publish or catalog ingest.

- Reference integration via lazymac2x/claude-skill-validator-api repo
Recommended MCP Servers
Journey fit
Building agent extensions is core Build work; validators belong where you craft and harden tooling before ship. Agent-tooling subphase catalogs MCP servers that support skill authoring, linting, and agent workspace hygiene.
How it compares
MCP validator service for skills, not a skill template generator or brainstorming methodology skill.
