# Dependency graph
requires:
  - phase: 01-03
    provides: TmuxSessionManager with create/list/destroy
  - phase: 01-01
    provides: StateManager for session state persistence
provides:
  - CLI entry point for session management (gsd-ocl)
  - Session resume with state validation
  - Orphan session cleanup functionality
affects: [02-claude-integration, 03-communication-bridge]

# Tech tracking
tech-stack:
  added: [argparse (stdlib)]
  patterns: [CLI subcommands pattern, mock-based testing]

key-files:
  created:
    - src/gsd_openclaw/cli.py
    - tests/test_cli.py
  modified:
    - src/gsd_openclaw/tmux_session.py
    - tests/test_tmux_session.py
    - pyproject.toml

key-decisions:
  - "Argparse for CLI - standard library, no dependencies"
  - "Exit code 1 for all errors - simple error handling"
  - "TmuxSessionError exception class for session-specific errors"

patterns-established:
  - "CLI subcommands: each command is a separate function with args parameter"
  - "Mock-based testing for tmux operations - no real tmux server needed"

# Phase 1 Plan 04: CLI Entry Point Summary

**CLI with create/list/destroy/resume/cleanup commands using argparse, plus session resume with state validation and orphan cleanup**

## Performance

- **Duration:** 8 min
- **Started:** 2026-03-10T16:52:20Z
- **Completed:** 2026-03-10T17:00:20Z
- **Tasks:** 4
- **Files modified:** 5

## Accomplishments
- Session resume functionality with state validation and schema version checking
- Automatic tmux session recreation when state exists but tmux session is missing
- Orphan session cleanup to remove tmux sessions without corresponding state files
- Full CLI with argparse providing all session management commands
- Package installable via pip with gsd-ocl entry point

## Task Commits

Each task was committed atomically:

1. **Task 1: Implement session resume with state validation** - `f877b3c` (feat)
2. **Task 2: Implement orphan session cleanup** - `8598b8e` (feat)
3. **Task 3: Implement CLI with argparse** - `4d14600` (feat)
4. **Task 4: Configure pyproject.toml with CLI entry point** - `8d0282a` (feat)

_Note: All tasks followed TDD pattern (RED-GREEN-REFACTOR)_

## Files Created/Modified
- `src/gsd_openclaw/cli.py` - CLI entry point with argparse subcommands
- `src/gsd_openclaw/tmux_session.py` - Added resume_session, get_session, cleanup_orphans, TmuxSessionError, CleanupResult
- `tests/test_cli.py` - Comprehensive CLI tests (16 tests)
- `tests/test_tmux_session.py` - Added resume and cleanup tests (11 new tests)
- `pyproject.toml` - Added CLI entry point and package configuration

## Decisions Made
- Argparse chosen for CLI - standard library, no external dependencies needed
- TmuxSessionError exception class for clear error handling in session operations
- CleanupResult dataclass to return both cleaned sessions and errors
- Exit code 1 for all CLI errors - simple and consistent error handling

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None - all tasks completed smoothly following TDD pattern.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Core infrastructure complete with workspace, state, tmux session, and CLI layers
- Ready for Phase 2: Claude Integration
- All 83 tests passing
