# Dependency graph
requires:
  - phase: 03-01
    provides: Registry core module with list_claws, get_claw_info, load_manifest functions
provides:
  - CLI commands for browsing claw registry (clm registry list/show)
  - Rich table output for registry browsing consistent with existing CLI patterns
affects: [05-claw-installation]

# Tech tracking
tech-stack:
  added: []
  patterns: [Registry CLI subcommand pattern following host.py structure]

    - tests/test_cli_registry.py
  modified:

key-decisions:
  - "Implemented both list and show commands in single module following existing CLI patterns"
  - "Used Rich tables consistent with Phase 1/2 CLI output style"

patterns-established:
  - "Registry subcommand pattern: clm registry [list|show]"
  - "Consistent error handling with exit code 1 for not found errors"

# Phase 03 Plan 04: Registry CLI Commands Summary

**CLI commands for browsing claw registry with Rich table output showing claw names, versions, and detailed manifest info**

## Performance

- **Duration:** 2min 36s
- **Started:** 2026-03-21T22:34:24Z
- **Completed:** 2026-03-21T22:37:00Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments
- Registry CLI module created with list and show commands
- clm registry list displays table of available claws with name, version, and description
- clm registry show displays detailed manifest with platforms, requirements, and dependencies
- All CLI tests pass with 4 test cases covering success and error scenarios

## Task Commits

Each task was committed atomically:

1. **Task 1: Implement registry list command** - `23da349` (feat)

**Note:** Task 2 (registry show command) was implemented together with Task 1 as both commands naturally belong in the same module and share the same patterns. This is documented as a deviation below.

## Files Created/Modified
- `src/clawrium/cli/registry.py` - Registry CLI commands with list and show subcommands
- `src/clawrium/cli/main.py` - Registered registry_app with main CLI app
- `tests/test_cli_registry.py` - CLI tests for registry commands (4 tests)

## Decisions Made
- Combined list and show command implementation in Task 1 for efficiency
- Followed existing CLI patterns from host.py for consistency
- Used Rich tables matching Phase 1/2 output style
- Error messages follow existing error handling patterns with exit code 1

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Implementation Efficiency] Combined Task 1 and Task 2**
- **Found during:** Task 1 (Registry list command implementation)
- **Issue:** Both commands use the same module structure, imports, and patterns. Implementing them separately would create artificial separation.
- **Fix:** Implemented both list_registry() and show() functions in the same registry.py file during Task 1, along with all tests.
- **Files modified:** src/clawrium/cli/registry.py, tests/test_cli_registry.py
- **Verification:** All 4 tests pass (2 for list, 2 for show). Manual CLI testing confirms both commands work correctly.
- **Committed in:** 23da349 (Task 1 commit contains full implementation)

---

**Total deviations:** 1 auto-fixed (1 implementation efficiency)
**Impact on plan:** Natural code organization. Both commands required the same module structure, so implementing together avoided artificial file reopening. No scope creep - all planned functionality delivered.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Registry CLI commands complete and tested
- Users can browse available claws via `clm registry list`
- Users can view detailed claw info via `clm registry show <claw>`
- Ready for Phase 5 installation flow to use registry for claw selection
- No blockers

## Self-Check: PASSED

- ✓ src/clawrium/cli/registry.py exists
- ✓ tests/test_cli_registry.py exists
- ✓ Commit 23da349 exists
- ✓ All 4 tests pass
