What problem does it solve? Completing an Agentic SDLC feature requires a safe local commit checkpoint: sealing any final integration changes, promoting the unchanged project branch to the exact verified tip, and cleaning up integration worktrees without risking force operations, pushes, or history rewrites. ## Core Features & Use Cases - Sealed Integration Commit: Creates at most one final integration commit with a message referencing FEAT-* and REQ-* IDs, guarded by a short-lived commit-authorization file. - Fast-Forward-Only Promotion: Promotes the project feature branch to the exact recorded SHA under a shared Git common-directory lock, with precheck and postcheck verification. - Non-Force Cleanup: Removes the integration worktree and deletes its branch only at the exact expected promoted SHA, never using force. - Use Case: After all SDLC waves pass validation, tests, and evaluation, the coordinator invokes this skill to seal the integration tip, fast-forward the feature branch, record commit evidence, and transition the feature state to committed. ## Quick Start Ask the Agentic SDLC coordinator to run $sdlc-commit after all validation, test, and evaluation evidence passes for the current feature.
