 - `automate` – expands regression coverage after implementation.
 - `ci` – bootstraps CI/CD pipelines aligned with TEA practices.
 - `test-design` – combines risk assessment and coverage planning.
-- `trace` – maps requirements to implemented automated tests.
+- `trace` – maps requirements to tests (Phase 1) and makes quality gate decisions (Phase 2).
 - `nfr-assess` – evaluates non-functional requirements.
-- `gate` – records the release decision in the gate file.
+- `test-review` – reviews test quality using knowledge base patterns and generates quality score.
+
+**Note**: The `gate` workflow has been merged into `trace` as Phase 2. The `*trace` command now performs both requirements-to-tests traceability mapping AND quality gate decision (PASS/CONCERNS/FAIL/WAIVED) in a single atomic operation.
 
 Each subdirectory contains:
 
-- `instructions.md` – the slim workflow instructions.
-- `workflow.yaml` – metadata consumed by the BMAD workflow runner.
+- `README.md` – comprehensive workflow documentation with usage, inputs, outputs, and integration notes.
+- `instructions.md` – detailed workflow steps in pure markdown v4.0 format.
+- `workflow.yaml` – metadata, variables, and configuration for BMAD workflow runner.
+- `checklist.md` – validation checklist for quality assurance and completeness verification.
+- `template.md` – output template for workflow deliverables (where applicable).
 
 The TEA agent now invokes these workflows via `run-workflow` rather than executing instruction files directly.
