What problem does it solve? When an AI-driven development workflow (case-run) needs to hand off a single GitHub Issue's implementation to an execution subagent, there must be a strict contract governing how work is delegated, how results are returned, and how failures are recovered. This Skill defines that adapter protocol so delegated implementation stays isolated, auditable, and recoverable. ## Core Features & Use Cases - Four-state result contract: Execution subagents return exactly one of completed-pr (with PR number/URL), blocked, failed, or delegation-unavailable, with PR bodies and Issue comments as the single source of truth. - Worktree isolation enforcement: All file edits are confined to the delegated worktree root (.worktrees/{N}-{type}/), with self-verification helpers and immediate failed status on violation. - Recovery and quality gates: Defines a 3-point receipt gate (result state, commit hash, PR URL), background delegation loss recovery via durable state, test-fix loops per test strategy item, and optional adversarial-review integration before implementation. - Use Case: A case-run orchestrator delegates Issue #980 to an execution subagent with a structured delegation prompt; the subagent implements, runs quality gates, creates a PR via agentdev_gh, and returns completed-pr with the PR URL. ## Quick Start Load this adapter skill when delegating a case-run Issue implementation to an execution subagent and follow its result contract and worktree isolation rules.
