What problem does it solve? Large, high-risk coding efforts with dependent phases often fail due to lost context, skipped reviews, and uncoordinated parallel work. This Skill provides a structured orchestration workflow that keeps plans, research, validation results, and review decisions in a persistent progress file. ## Core Features & Use Cases - Phased Planning and Delegation: Breaks large work into coherent delivery phases, assigns specialist lanes, and tracks ownership in a persistent markdown state file under .slim/deepwork/. - Mandatory Review Gates: Requires an Oracle review after each phase with a bounded re-review budget, plus structure scans when module boundaries change. - Scheduler Discipline: Coordinates background jobs, waits for completion events, and prevents advancing phases while results are unreconciled. - Use Case: When migrating a codebase across architectural boundaries, use this Skill to plan phases, delegate implementation to specialists, gate each phase with reviews, and commit only at validated delivery boundaries. ## Quick Start Ask the AI to run the deepwork workflow for a large multi-phase refactoring task and have it create a progress file, plan phases, and gate each phase with reviews.
