builder-leadDELIVER LEAD ENGINEER — the orchestration architect of a DELIVER cycle. Ingests a complete ROADMAP, analyses the full codebase, determines the required stack, identifies shared infrastructure across roadmap items, decomposes every item into parallelisable tasks, estimates token budgets, and produces
coverage-loop-agentAutomated behaviour-pinning agent. Finds the behaviour least pinned by tests (the file with the most unpinned lines), adds the missing coordinate(s) that locate its correct implementation, and loops until every behaviour is pinned or the user stops. 100% coverage is the floor that results, never the
ds-step-0-planCreates and maintains the implementation plan artifact with checklist and resumption instructions. Spawned by the lifecycle-orchestrator or DELIVER at the start of a new roadmap item's lifecycle.
ds-step-1-earsProduces EARS specification updates with unique requirement IDs and traceability hooks. Spawned after step-0-plan completes and PLAN_COMPLETE sentinel is present.
ds-step-2-feature-docsWrites .feature behavior documentation with happy, unhappy, and abuse scenarios mapped to EARS IDs. Spawned after EARS_COMPLETE sentinel is present and EARS-REVIEWER has passed.
ds-step-3-testsAuthors failing test suite aligned to EARS and Gherkin contracts, without implementing production code. Spawned after FEATURE_COMPLETE sentinel is present and BDD-REVIEWER has passed.
ds-step-4-first-test-runRuns full test suite to confirm expected new failures and document the feature gap map. Spawned after TESTS_WRITTEN::RED sentinel is present.
ds-step-5-implementationImplements minimum production code to satisfy failing tests while preserving architecture and quality constraints. Spawned after GAP_MAP_COMPLETE sentinel is present and TEST-DESIGN-REVIEWER has passed.
ds-step-6-green-runDrives full test suite to green, validates regression-free status, and confirms behavior intent is met. Spawned after IMPL_COMPLETE::GREEN sentinel is present.
ds-step-7-syncSynchronizes branch with upstream and revalidates green status after conflict resolution. Spawned after GREEN_RUN_COMPLETE sentinel is present.
ds-step-8-commit-messageProduces structured commit narrative with motivation, scope, testing evidence, and roadmap linkage. Spawned after SYNC_COMPLETE sentinel is present.
ds-step-9-commit-pushFinalizes delivery. Standalone cycle — executes commit + push, updates roadmap/plan completion metadata, returns delivery evidence. Engine PLAN-scope (FLEET) — commits the green slice to the build branch and emits DELIVERY_COMPLETE keyed to branch HEAD for the engine to land (NO push, NO roadmap/STA
ds-step-story-testsAuthors story-level and end-to-end (E2E) tests that exercise the feature through its real interface — browser, CLI, or API. Spawned after IMPL_COMPLETE::GREEN sentinel is present and before ds-step-7-sync. Owner of STORY_PROVEN sentinel.
flaky-test-fixerDiagnoses and eliminates flaky tests. A flaky test is one that sometimes passes and sometimes fails without any code change. Root causes are: arbitrary timing waits (waitForTimeout, sleep), implicit async ordering assumptions, shared mutable state between tests, and race conditions in the production
