Cursor implements and revises a hybrid search service

Dodds used Cursor with GPT-5.4 to add lexical retrieval to his semantic search. Production blocking exposed an architectural flaw, so later agent work moved search into a unified Worker.

Suggested prompt

Suggested prompt written by Agents In Use, not the source author. Replace bracketed inputs and review tool permissions first.

Inspect [search service] and reproduce missing results for exact names. Propose a minimal retrieval change, implement on a branch and verify representative queries. Check cold requests for blocking index maintenance. Keep deployment separate and report both relevance failures and operational risks.

How the agent did it

  1. Inspect the existing search, diagnose missing exact-term results and prepare an implementation plan.
  2. Implement lexical retrieval and test indexing and runtime behavior.
  3. Investigate production stalls and replace foreground index work with a unified search Worker.
