What problem does it solve? Turning an approved solution into an executable implementation plan is error-prone: phases get sliced by layer instead of vertically, acceptance criteria lose their link to the phases and tests that satisfy them, and historical context from past work is missed. This Skill automates that final planning stage so the plan is ready for phased execution. ## Core Features & Use Cases - Context Enrichment: Spawns a subagent to mine git history and completed task folders for related decisions, then merges findings into context.md and flags drifted file paths. - Vertical-Slice Phase Design: Breaks the solution into atomic execution phases with a walking-skeleton first phase, an explicit dependency DAG, per-step verify checks, and commit-plus-verification endings. - AC Traceability Backfill: Updates each pd-ac card in the Verification tab with the phase numbers and test file paths that cover it. - Use Case: After a solution is approved in plan.html, run this Skill to produce the Plan tab with a mermaid execution sequence, then hand off to /commit-task and /execute-task for implementation. ## Quick Start Write the plan for the current task now that the solution is approved.
