Perform a concise, prioritized review of current code changes with concrete fixes, using the repository’s configured review policy and guides.
Seed a target repository with the required harness contract files and directory structure, and optionally draft initial repository-specific content when enough context is available.
Convert an informal feature idea into a concise, implementation-ready PRD in a work item directory under docs/exec-plans/current/.
Transform a PRD into a practical FDD in a work item directory under docs/exec-plans/current/ with concrete boundaries, interfaces, data impacts, and verification strategy.
Produce a slice-level detailed design doc at <work_item_dir>/design/<slice_slug>.md by mapping slice responsibilities, interfaces, edge cases, and tests to the work item requirements.
Implement one phase from a work item plan under docs/exec-plans/current/ using the repository contract as the source of truth.
