Original: Coverage Before Creativity: The RAG Gate That Keeps My Blog Pipeline Honest

Short summary

The author builds a RAG sufficiency gate that validates evidence breadth before any blog draft is generated, preventing confident-but-shallow output. Three query lanes (curated highlights, fixed RAG pool, recent commits) fan out to force coverage across different codebase regions. Only candidates passing a breadth check proceed to excerpt pinning and drafting, ensuring the generator works from wide evidence rather than a narrow cluster.

  • •Evidence quality is gated before generation: breadth validation rejects topics with insufficient retrieval spread
  • •Three query lanes catch different failure modes — curated anchors, fixed pool forces architectural variety, commit queries add temporal relevance
  • •Shared utilities centralize the sufficiency check close to the evaluation logic in Supabase functions
