+# Phase 1 Plan 02: CLI Entry Point Summary
+
+**Commander-based CLI with cw --help, cw --version, and placeholder commands for status/agent/task**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-01-30T12:12:16Z
+- **Completed:** 2026-01-30T12:13:33Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Created CLI foundation using Commander with name, description, and version
+- Added placeholder commands: status, agent, task (log "not implemented")
+- Added graceful error handling for uncaught exceptions and unhandled rejections
+- Verified global installation works via npm link
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create CLI with commander** - `bf7ba66` (feat)
+2. **Task 2: Enable global installation via npm link** - No commit (verification only, no code changes)
+
+**Plan metadata:** (this commit)
+
+## Files Created/Modified
+
+- `src/cli/index.ts` - CLI module with createCli() factory exporting configured Commander program
+- `src/bin/cw.ts` - Updated entry point to use createCli() with error handling
+
+## Decisions Made
+
+- Task 2 required no code changes since package.json bin field and shebang were already correctly configured in 01-01
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- CLI foundation complete with help and version display
+- Placeholder commands ready for implementation in later phases
+- Ready for 01-03: Process Management
