CHAINLOGIC Why is this query slow?

What changes in Claude's response

Each conclusion gets numbered: 1) The query has no index on user_id. 2) Postgres is doing a sequential scan, confirmed by the EXPLAIN output. 3) The table has 4M rows. 4) Sequential scan of 4M rows takes ~800ms. Therefore: add an index on user_id. You can spot-check each step instead of trusting the final answer.

When NOT to use CHAINLOGIC

Skip when you trust the conclusion and just want the answer. CHAINLOGIC is verification overhead — useful when you're going to act on the answer in production, wasteful when you're just curious.
