blockmatic Purpose and inputs
Compare implementation to the repository's product overlay (_first/.../PRODUCT.md or equivalent). Durable goals, priorities, and horizons belong to /f-product. Chat only unless the user names a file.
Steps
- Load FIRST in the repository's order and read the product overlay. If it is missing, stop and point at
/f-product. - Diff code against named horizons and the feature map. List shipped, in-progress, and overlay items with no matching code.
- Do not invent features, effort buckets, or a second backlog. Optional diagrams may illustrate the overlay, not a new roadmap.
- Ask whether the user wants
/f-product(durable change) or/plan-feature(implementation slices for an already-authorized item).
Verification
- Every listed item cites PRODUCT.md or an existing issue/PR.
- No new priorities were minted from a codebase scan.
- No files were written unless requested.
Handoff
Return overlay gaps and the owning station. Do not offer a feature plan unless the user asked.
