What problem does it solve? Large, high-risk coding efforts with multiple dependent phases often fail due to lost context, unreviewed intermediate work, and poor coordination between specialist agents. This Skill structures those efforts into planned phases with review gates and a persistent progress file. ## Core Features & Use Cases - Phased Orchestration: Splits large work into coherent implementation phases based on dependencies and delivery boundaries, delegating to specialist agents like @designer, @fixer, and @librarian. - Oracle Review Gates: Runs an @oracle review after each planned phase, with batched remediation passes and follow-up reviews only when decisions or risks change. - Persistent Session State: Maintains a markdown progress file under .slim/deepwork/ capturing research findings, plans, review notes, and validation results, kept git-local via .gitignore and .ignore rules. - Use Case: When migrating a cross-cutting architecture that cannot be partially shipped, activate deepwork to plan phases, delegate specialists, gate each phase with Oracle reviews, and track all decisions in one progress file. ## Quick Start Use the deepwork skill to plan and orchestrate this large multi-phase migration with specialist delegation and Oracle review gates after each phase.
