key-decisions:
  - "Subcommand dispatch pattern for handling push/pop/apply/list/drop"
  - "Output capture with subprocess.run for _get_most_recent_shelve()"
  - "Git-compatible error message for drop with no stashes"

patterns-established:
  - "Subcommand dispatch: Parse args[0] as subcommand, route to _handle_* helpers"
  - "State queries: Use subprocess.run with capture_output for querying sl state before acting"

# Phase 18 Plan 01: Stash Command Handler Summary

**Stash command handler with subcommand dispatch (push, pop, apply, list, drop) translating git stash to sl shelve/unshelve**

## Performance

- **Duration:** 2 min
- **Started:** 2026-01-20T01:08:23Z
- **Completed:** 2026-01-20T01:10:19Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Created cmd_stash.py with handle() function and subcommand dispatch
- Implemented all 5 subcommand handlers: push, pop, apply, list, drop
- Added _get_most_recent_shelve() helper for drop without arguments
- Integrated stash routing in gitsl.py dispatch

## Task Commits

Each task was committed atomically:

1. **Task 1: Create stash command handler with subcommand dispatch** - `e17b9dd` (feat)
2. **Task 2: Update gitsl.py dispatch routing** - `9db6199` (feat)

## Files Created/Modified
- `cmd_stash.py` - Stash command handler with subcommand dispatch for push/pop/apply/list/drop
- `gitsl.py` - Added cmd_stash import and dispatch routing

## Decisions Made
- **Subcommand dispatch pattern:** Parse first argument as subcommand, dispatch to _handle_* helpers - consistent with git stash structure
- **Output capture for state:** Use subprocess.run with capture_output to query sl shelve --list before deleting - required since sl shelve --delete needs explicit name
- **Git-compatible error:** Return "No stash entries found." with exit code 1 for drop when no stashes exist - matches git behavior

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Stash handler complete and routing active
- Ready for 18-02 E2E tests to verify all stash operations
- All subcommands (push, pop, apply, list, drop) implemented
