Add vector search / RAG · prompt 3 · Codex CLI · week 2026-W44

Codex CLI built it with @qdrant/js-client-rest

Prompt: I need a vector database for similarity search in this app. Set it up and add an API route to upsert and query.

Grader: The agent chose Qdrant, added POST /api/vectors/upsert and /api/vectors/query with bearer auth, zod validation and metadata filters, and the build passed. It could not start Docker, so the database was never run live, and it worked around an undici advisory with an npm override.
