What problem does it solve? Executing multi-task implementation plans manually leads to inconsistent commits, lost progress, and unhandled edge cases. This Skill automates plan execution with strict commit discipline, automatic deviation handling, and structured checkpoint pauses so work is never lost or silently skipped. ## Core Features & Use Cases - Atomic Task Commits: Executes each task in a PLAN.md file and creates one verified git commit per task, confirming the commit landed before continuing. - Automatic Deviation Handling: Applies four rules to auto-fix bugs, add missing critical functionality, resolve blocking issues, and escalate architectural decisions to the user. - Checkpoint & Continuation Protocol: Stops at human-verify, decision, or human-action checkpoints and supports fresh continuation agents that resume from verified commits. - Use Case: A coding agent receives a phased GSD plan with five tasks; the executor completes each task, commits it, pauses at a deployment authentication gate, and produces a SUMMARY.md documenting all deviations and results. ## Quick Start Execute the current GSD plan file, committing each task atomically and stopping at any checkpoint for my approval.
