Detects post-training knowledge gaps, resolves them automatically, and delivers your team's decisions via MCP to Claude, Cursor, Copilot, and 10+ tools. 767 tests  ·  23 expert skills  ·  10 ecosystems  ·  11 languages  ·  14 AI tools --- The Problem Your AI writes code using knowledge from its training data. Your project uses libraries released after that cutoff. The result: hallucinated APIs, deprecated patterns, and code that doesn't compile. Your team's decisions — use PaymentIntents, not Charges; always wrap API responses; never useEffect for data fetching — exist nowhere in the AI's training data. The code it generates is idiomatic React or idiomatic Node — just not idiomatic yours . When we asked Claude to write code for botid (published 2026-03-03, post-training): \"I can't verify the botid package's actual API. I won't output code for a package whose API I can't verify. Guessing function names and signatures would likely give you broken code.\" The Fix BookLib detects every post-training API in your codebase and resolves the gaps automatically. Real output: booklib analyze on vercel/ai-chatbot — 82 dependencies, 274 post-training APIs across 158 files. Without BookLib — AI uses AI SDK v5 patterns from training data: With BookLib — AI gets v6 docs injected at runtime: --- Getting Started Requires Node.js = 18.
