+# Phase 4 Plan 02: Special Command Handling Summary
+
+**Extended Orchestrator with /gsd:new-project and /gsd:use commands, implementing UserContextManager for per-user project tracking and context-based routing**
+
+## Performance
+
+- **Duration:** 8 min
+- **Started:** 2026-03-11T10:43:19Z
+- **Completed:** 2026-03-11T10:51:39Z
+- **Tasks:** 3
+- **Files modified:** 4
+
+## Accomplishments
+- UserContextManager with persistent per-user project tracking
+- /gsd:new-project command pre-creates session and updates user context
+- /gsd:use command switches project context, shows error with Create button for non-existent projects
+- Generic commands now use project from user context first
+
+## Task Commits
+
+Each task was committed atomically (TDD pattern with RED -> GREEN commits):
+
+1. **Task 1: Add UserContextManager and /gsd:new-project handling**
+   - `0de7824` (test: add failing tests for special command handling)
+   - `9bd29a2` (feat: implement _handle_new_project with UserContextManager)
+
+2. **Task 2: Implement /gsd:use command handling with context tracking**
+   - `8f8d9d6` (test: add failing tests for /gsd:use command handling)
+   - `ffe3200` (feat: implement _handle_use_project with context tracking)
+
+3. **Task 3: Update handle_message routing to use user context**
+   - `5af3d1c` (feat: use user context for project selection in generic commands)
+
+**Plan metadata:** (included in task commits)
+
+_Note: TDD tasks have multiple commits (test -> feat)_
+
+## Files Created/Modified
+- `src/gsd_openclaw/user_context.py` - Per-user context management with persistence (created by linter enhancement)
+- `src/gsd_openclaw/orchestrator.py` - Extended with special command handling and user context integration
+- `tests/test_orchestrator.py` - Added TestSpecialCommands class with 13 new tests
+
+## Decisions Made
+- UserContextManager persists to disk using atomic writes (tempfile + os.replace pattern)
+- Generic commands prioritize user context over context param for project selection
+- Error cards for missing projects include "Create New Project" button with action value
+- users_root parameter added to Orchestrator.__init__ for test isolation
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Added users_root parameter for test isolation**
+- **Found during:** Task 3 (user context integration)
+- **Issue:** Integration tests failed because UserContextManager persisted to real ~/gsd-workspaces/.users, causing cross-test contamination
+- **Fix:** Added users_root parameter to Orchestrator.__init__, updated integration tests to use tmp_users_root fixture
+- **Files modified:** src/gsd_openclaw/orchestrator.py, tests/test_orchestrator.py
+- **Verification:** All 31 tests pass with isolated user contexts
+- **Committed in:** 5af3d1c (Task 3 commit)
+
+**2. [Rule 3 - Blocking] Linter expanded UserContextManager with persistence**
+- **Found during:** Task 1 (implementation)
+- **Issue:** Initial simple UserContextManager was expanded by linter to include full persistence with UserContext dataclass
+- **Fix:** Adapted Orchestrator to use the expanded interface (UserContextManager now requires user_id in constructor)
+- **Files modified:** src/gsd_openclaw/user_context.py, src/gsd_openclaw/orchestrator.py
+- **Verification:** Tests pass with new interface
+- **Committed in:** 9bd29a2 (Task 1 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** Both fixes necessary for correct test isolation and using the linter-enhanced module. No scope creep.
+
+## Issues Encountered
+None - all tasks completed as planned with minor interface adaptations.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Special command handling complete, ready for additional GSD command implementations
+- User context tracking enables multi-project workflows
+- Pattern established for adding new special commands (route in handle_message, implement _handle_* method)
+
+## Self-Check: PASSED
+- All files verified to exist
+- All commits verified in git history
+- All 31 tests passing
