 - Mark phase complete: status → "Complete"

+**Only run when phase is complete (all plans have SUMMARYs).**
+
+When a phase completes, mark its requirements as Complete in REQUIREMENTS.md.
+
+**1. Get phase number from completed plan:**
+```bash
+# Extract phase number from plan path (e.g., 03-auth/03-02-PLAN.md → 03)
+PHASE_NUM=$(echo "$PLAN_PATH" | grep -oE '[0-9]+' | head -1)
+```
+
+**2. Find requirements for this phase in ROADMAP.md:**
+```bash
+# Look for Requirements: line in phase section
+grep -A5 "Phase ${PHASE_NUM}:" .planning/ROADMAP.md | grep "Requirements:"
+```
+
+Extract the REQ-IDs (e.g., "AUTH-01, AUTH-02, AUTH-03").
+
+**3. Update REQUIREMENTS.md traceability table:**
+
+For each REQ-ID covered by this phase:
+- Find the row in the Traceability table
+- Change Status from "Pending" to "Complete"
+
+Example before:
+```markdown
+| AUTH-01 | Phase 1 | Pending |
+| AUTH-02 | Phase 1 | Pending |
+```
+
+Example after:
+```markdown
+| AUTH-01 | Phase 1 | Complete |
+| AUTH-02 | Phase 1 | Complete |
+```
+
+**4. Skip if:**
+- REQUIREMENTS.md doesn't exist (older projects without requirements tracking)
+- Phase has no Requirements: line in ROADMAP.md
+- More plans remain in phase (not yet complete)
