What problem does it solve? Implementing a planned specification often requires babysitting: decomposing work, running phases, verifying each stage, and recovering from failures. This Skill autonomously executes a planned OpenSpec change end-to-end inside explicit boundaries and hard verification gates, so implementation proceeds without constant supervision. ## Core Features & Use Cases - Autonomous Phase Execution: Reads the planned OpenSpec change, decides whether to decompose it into smaller phase specs, and implements each stage in isolated git worktrees with child agents or Jules delegation. - Independent Audit Gates: Verifies every phase against the phase ledger, OpenSpec task checkboxes, and verification scripts, fixing failures autonomously within a retry budget before continuing. - State Tracking and Handoff: Maintains .sdlc/phase-ledger.md, .sdlc/run.json, and .sdlc/state.md, then prepares a local preview and hands off to sdlc-verify. - Use Case: After planning a feature that touches both frontend and backend, invoke this Skill to split the work into vertical phases, delegate implementation to Jules via GitHub issue labels, audit each phase's diff, and receive a preview URL plus the exact next verification command. ## Quick Start Use sdlc-orchestrate to implement the planned OpenSpec change for my feature and stop when it is ready for verification.
