+# Phase 11 Plan 1: Parallelization Frontmatter Summary
+
+**Added frontmatter fields (parallelizable, depends_on, files_exclusive) to plan template and config reading step to plan-phase workflow**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-01-12T20:30:00Z
+- **Completed:** 2026-01-12T20:34:00Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Added three parallelization frontmatter fields to phase-prompt.md template
+- Added frontmatter_guidance section explaining when to use each field
+- Updated good_examples with parallel and sequential plan examples
+- Added read_parallelization_config step to plan-phase.md workflow
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add parallelization frontmatter to phase-prompt.md** - `560ef34` (feat)
+2. **Task 2: Add read_parallelization_config step to plan-phase.md** - `8e67241` (feat)
+
+## Files Created/Modified
+
+- `get-shit-done/templates/phase-prompt.md` - Added parallelizable, depends_on, files_exclusive fields with guidance
+- `get-shit-done/workflows/plan-phase.md` - Added read_parallelization_config step after load_project_state
+
+## Decisions Made
+
+- Default parallelizable to false for safety (opt-in to parallel execution)
+- files_exclusive field enables conflict detection by execute-phase
+- Config reading happens early (priority="second") so planning behavior is informed throughout
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Next Step
+
+Ready for 11-02-PLAN.md (Add parallel-aware step to plan-phase workflow)
