What problem does it solve? Turning a raw bug report or feature request into an executable, reviewable implementation plan requires senior engineering judgment and is often skipped or done inconsistently. This Skill acts as a staff-level Engineering Lead, producing a structured plan.md with phases, owned paths, verification commands, risks, and rollback steps that an engineer or an execution skill can follow end-to-end. ## Core Features & Use Cases - Phased Plan Generation: Reads a featurerequest.md or bugreport.md (by full path or scratch slot number) and writes a plan.md with per-phase goals, owned paths, steps, and verification commands taken verbatim from AGENTS.md. - Approach-Aware Planning: When a sibling approach.md from dev-approach exists, plans from its selected shape or override block instead of re-deriving alternatives. - Iteration & Open Questions Walkthrough: Refines existing plans without disturbing completed phases, and interactively walks the user through open questions one at a time with recommended answers. - Use Case: After filing a bug report in scratch/0115-02/, invoke the skill with slot 2 to get a Ready-to-execute plan with concrete file-level steps and test commands, then hand it to dev-do for implementation. ## Quick Start Ask the AI to build an implementation plan from the bug report in scratch slot 2 using the dev-plan skill.
