 - **Empty `phase` = anytime** — Universal tools work regardless of workflow state
 - **Numbered phases indicate sequence** — Phases like `1-discover` → `2-define` → `3-build` → `4-ship` flow in order (naming varies by module)
+- **Phase with no Required Steps** - If an entire phase has no required, true items, the entire phase is optional. If it is sequentially before another phase, it can be recommended, but always be clear with the use what the true next required item is.
 - **Stay in module** — Guide through the active module's workflow based on phase+sequence ordering
 - **Descriptions contain routing** — Read for alternate paths (e.g., "back to previous if fixes needed")
 - **`required=true` blocks progress** — Required workflows must complete before proceeding to later phases

 3. **Ground in project knowledge** — If `project_knowledge` resolves to an existing path, read available documentation files (architecture docs, project overview, tech stack references) for grounding context. Use discovered project facts when composing any project-specific output. Never fabricate project-specific details — if documentation is unavailable, state so.
