Summary

Triggered after a brainstorm doc is approved and present at docs/brainstorms/<workflow_id>.md. Refuses to proceed if that file does not exist. Derives research queries from the brainstorm. Runs three tracks in parallel — codebase patterns, framework/library docs, prior solutions via substrate-read. Produces docs/research/<workflow_id>.md with valid workflow-doc frontmatter (type: research) and a ## Summary block of ≤5 lines, followed by one citable section per track.

Procedure

Step 1 — Verify the brainstorm doc exists

Before doing anything else, check that docs/brainstorms/<workflow_id>.md exists.

If the file does not exist, stop immediately and output:

Cannot start research: no approved brainstorm doc found at docs/brainstorms/<workflow_id>.md.
Run the clarify skill first, or pass the correct workflow_id.

Do not proceed.
