What problem does it solve? Turning a resolved design document into an actionable, trackable implementation plan is error-prone: tasks get lost, verification steps are skipped, and downstream tools like Trello sync fail on malformed structure. This Skill converts a grilled design doc plus .work/FINDINGS.md into a properly structured .work/PLAN.md that /sync-trello and /dev-brief consume unchanged. ## Core Features & Use Cases - Structured plan generation: Emits Goals, Micro-Goals, and Tasks where every Task carries a verify sub-bullet — the command that proves the task is done. - Dual format support: Detects flat vs. index+detail plan layouts (.work/plan/ directory) and appends new Goals without clobbering existing ones or their Trello card IDs. - Conditional security gate: Offers a /threat-model design review only when the plan exposes an HTTP surface or handles sensitive data, then recommends /sync-trello at the end. - Use Case: After /grill-me resolves the open questions in a design doc for a new authenticated API, run /write-plan to produce a PLAN.md with FR-NN-cited tasks, get prompted for a threat-model review, and sync the result to your Trello board. ## Quick Start Run /write-plan with the path to your design doc to generate an executable .work/PLAN.md with verifiable tasks.
