What problem does it solve?
This skill eliminates the risk of using outdated, incorrect, or mismatched library documentation when writing or modifying code, which commonly causes bugs, deprecated API usage, and wasted debugging time.
Core Features & Use Cases
- Proactive Documentation Querying: Automatically fetches the correct, version-specific docs for any project dependency before you write or modify code, no manual searching required.
- Accurate Library ID Resolution: Uses the ctx7 CLI to find the exact library ID (including version-specific variants) to avoid fetching irrelevant or wrong documentation.
- Use Case: When implementing a new feature with Next.js 14, this skill first resolves the correct v14 library ID, then fetches the exact middleware setup docs for that version, so you never accidentally use outdated v13 syntax.
Quick Start
