What problem does it solve? Manually shepherding a GitHub issue from implementation through QA review to merge consumes developer attention and context. This Skill supervises the full cycle autonomously, spawning fresh sub-agents for each phase so one session can drain an entire queue of issues without context exhaustion. ## Core Features & Use Cases - Autonomous DEV/QA loop: Spawns a fresh Developer sub-agent to implement an issue, then an independent QA sub-agent to verify it, bouncing between them up to 3 times before escalating to a human. - Duplicate-claim prevention: Claims issues via flow:* labels with verify-after-claim comment arbitration, sweeps stale claims, and enforces a leave-clean invariant (no dirty trees, stashes, or orphaned branches). - Multi-tracker support: Drives GitHub issues by default or Azure DevOps work items via --source devops, emitting a machine-readable IMPL-LOOP-TERMINAL sentinel on every terminal path for external queue watchers. - Use Case: Run /implementation-loop --all to drain every flow:ready-dev issue in the repo, with QA squash-merging each passing PR to main and parking weak specs as flow:needs-human. ## Quick Start Ask the agent to run /implementation-loop --all to drive every flow:ready-dev GitHub issue through development and QA until merged or escalated.
