+5. **Phase 4 executes** (task-generate-agent if --agent) → Task generation → Reports final summary
 
 **Auto-Continue Mechanism**:
 - TodoList tracks current phase status
 - After each phase completion, automatically executes next pending phase
-- **Phase 3.5 requires user interaction** - answers clarification questions (up to 5)
-- If no ambiguities found, Phase 3.5 auto-skips and continues to Phase 4
+- All phases run autonomously without user interaction (clarification handled in brainstorm phase)
 - Progress updates shown at each phase for visibility

-### Phase 3.5: Concept Clarification (Quality Gate)
+### Phase 3.5: Pre-Task Generation Validation (Optional Quality Gate)
 
-**Command**: `SlashCommand(command="/workflow:concept-clarify --session [sessionId]")`
+**Purpose**: Optional quality gate before task generation - primarily handled by brainstorm synthesis phase
 
-**Purpose**: Quality gate to verify and clarify analysis results before task generation
+**Note**: Concept enhancement and clarification are now handled in `/workflow:brainstorm:synthesis` Phase 2.5 during brainstorming. This phase is reserved for future validation extensions.
 
-**Input**: `sessionId` from Phase 1
+**Current Behavior**: Auto-skip to Phase 4 (Task Generation)
 
-**Behavior**:
-- Auto-detects plan mode (ANALYSIS_RESULTS.md exists if Phase 3 executed)
-- Interactively asks up to 5 targeted questions to resolve ambiguities
-- Updates ANALYSIS_RESULTS.md with clarifications (if file exists from Phase 3)
-- Pauses workflow for user input (breaks auto-continue temporarily)
+**Future Enhancement**: Could add additional validation steps like:
+- Cross-reference checks between conflict resolution and brainstorm analyses
+- Final sanity checks before task generation
+- User confirmation prompt for proceeding
 
-**Parse Output**:
-- Verify clarifications added to ANALYSIS_RESULTS.md (if Phase 3 executed)
-- Check recommendation: "PROCEED" or "ADDRESS_OUTSTANDING"
+**TodoWrite**: Mark phase 3.5 completed (auto-skip), phase 4 in_progress
 
-**Validation**:
-- If Phase 3 executed: ANALYSIS_RESULTS.md updated with `## Clarifications` section
-- All critical ambiguities resolved or documented as outstanding
-
-**TodoWrite**: Mark phase 3.5 completed, phase 4 in_progress
-
-**After Phase 3.5**: Return to user showing clarification summary, then auto-continue to Phase 4
-
-**Skip Conditions**:
-- If `/workflow:concept-clarify` reports "No critical ambiguities detected", automatically proceed to Phase 4
-- User can skip by responding "skip" or "proceed" immediately
+**After Phase 3.5**: Auto-continue to Phase 4 immediately
