What problem does it solve? Multi-step implementation plans often get interrupted or partially completed, leaving developers unsure where to resume and risking skipped dependencies or unvalidated changes. This Skill drives a plan folder under tmp/ to completion by resuming from the first unfinished step and validating after each one. ## Core Features & Use Cases - Resumable execution: Reads the plan README and step files to find the first step not marked done, then continues in dependency order. - Step-by-step validation: Runs the validate workflow after each step and stops on failure rather than forcing a green result. - Idempotent and reviewable: Each step stays a standalone, reviewable unit; work is left uncommitted for the maintainer to commit. - Use Case: You have a plan folder tmp/storage-gcs-backend/ with five steps, two already done. Invoke this Skill to apply steps three through five in order, validating the affected Go modules after each. ## Quick Start Apply the remaining steps of the plan in tmp/storage-gcs-backend/ and validate after each step.
