What problem does it solve? Code changes often use third-party libraries with incorrect signatures, deprecated methods, or version-incompatible APIs that slip past review. This Skill automatically validates every imported library in modified files against official Context7 documentation, catching API misuse before it reaches production. ## Core Features & Use Cases - Import Extraction and Resolution: Parses JavaScript, TypeScript, and Python imports from modified files, then resolves each library to its Context7 documentation ID. - API Usage Validation: Checks function signatures, parameter types, return values, and deprecated methods against official docs, flagging issues with severity levels from CRITICAL to MINOR. - Structured QA Reports: Generates a JSON validation report saved to the story's QA folder, integrating directly into the review-build pipeline as Phase 6.0. - Use Case: During a story review, run validation on changed files to discover that useQuery({ cacheTime: 5000 }) uses a deprecated option and should be migrated to gcTime, with a suggested fix and docs link included. ## Quick Start Ask the QA agent to validate the libraries used in story 6.3 by running validate-libraries with the story ID.
