# Component API validator A skill for auditing the public API surface of a component library — prop naming consistency, type coverage, default value patterns, breaking change detection, and alignment with the design-to-code contract. Treats the component API as infrastructure: the public contract that consuming teams depend on. ## Before you begin: verify references Before doing anything else, confirm that every file listed in this skill's frontmatter `references:` field exists at its relative path from this SKILL.md. If any are missing, stop — the install is incomplete. This usually means a third-party installer (for example `npx skills install`) flattened the skill into a standalone folder and dropped the repo-root `knowledge-notes/` directory this skill depends on. Tell the user to reinstall using a supported method from `1-INSTALL.md` (git clone, or the `.plugin` bundle in Cowork) and to run `verify-install.sh` from the install root to confirm the fix. Only proceed without the references if the user explicitly says to — and if they do, state clearly in your output that it was produced in degraded mode without the pack's reference material. ## Context A component library's most important output is not its visual rendering — it is its API. The props, types, defaults, and composition patterns form a contract with every consuming team. When that contract is inconsistent (some components use `variant`, others use `type`, others use `appearance` for the same concept), uncl...
