AND Implement

Implement the complete claimed delivery unit from its GitHub Package Contract. Work in one isolated worktree and finish with a committed, verified, reviewed diff plus durable implementation evidence.

Runtime Contracts

Use and-workflow-contract with work-records.md and delivery-units.md for Read Delivery Unit, Record Receipt, and Reference Implementation Artifact. Load acceptance-gate.md when the Package Contract declares an Acceptance Gate. When the repository-owned review is called with AND context, load review-attestation.md for its attestation operation. Read local-cleanup.md directly before creating a worktree-owned local resource and again before finalizing its reviewed handoff. Read deployment-handoff.md directly for Read Deployment Handoff before that handoff. Route incomplete setup or a missing contract to setup-and.

Real tdd and code-review skills are required. If either is unavailable, name the missing skill and stop with the documented installation route. Give tdd the Package Contract's agreed seam as confirmed input where test-first work is practical. Use code-review against the retained fixed point with the complete Package Contract and every acceptance-bearing PRD child supplied as the Spec.

Preconditions

Begin only when the current actor owns or is delegated the complete open ready-for-agent delivery unit and no external blocker remains. A PRD claim covers its parent and every child.

Route an unready or unowned unit to the smallest upstream AND skill. If the current head already has clean implementation evidence, an authoritative Deployment disposition, a valid optional Cleanup handoff when resources survive, a complete Deployment Manifest when Deployment is custom, and every conditional authority reports no remaining Implement action, route to and-finish. If implementation and review are clean but Deployment is missing or stale, or an emitted Cleanup handoff is malformed or stale, resume at handoff classification; route a linked non-authoritative finish proposal to and-finish before implementation resumes.
