# Dependency graph
requires:
  - phase: 24-status-and-add-flags
    provides: flag translation patterns for status and add commands
provides:
  - COMM-01 through COMM-08 commit flag support
  - BRAN-01 through BRAN-09 branch flag support
  - signoff trailer implementation
  - bookmark copy implementation
affects: [25-commit-and-branch-flags-tests, future-flag-phases]

# Tech tracking
tech-stack:
  added: []
  patterns: [amend-command-switching, signoff-trailer-append, two-step-bookmark-copy]

key-files:
  created: []
  modified: [cmd_commit.py, cmd_branch.py]

key-decisions:
  - "sl amend defaults to no-edit, so add -e flag for git's default editor behavior"
  - "signoff implemented via custom trailer appending, not sl config"
  - "branch -c uses two-step: get commit hash, create new bookmark"
  - "verbose branch uses template instead of sl -v flag"

patterns-established:
  - "Command switching: use different sl command based on flag (commit vs amend)"
  - "Trailer appending: modify message before passing to sl"
  - "Two-step operations: query then act for missing sl features"

# Phase 25 Plan 01: Commit and Branch Flags Summary

**Commit amend/signoff and branch rename/copy/show-current flags via COMM-01 through COMM-08 and BRAN-01 through BRAN-09**

## Performance

- **Duration:** 5 min
- **Started:** 2026-01-21T22:02:15Z
- **Completed:** 2026-01-21T22:07:09Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Extended cmd_commit.py with --amend, --no-edit, -F/--file, --author, --date, -v, -s/--signoff, -n/--no-verify
- Extended cmd_branch.py with -m, -a, -r, -v, -l, --show-current, -t, -f, -c
- Implemented custom signoff trailer via helper functions
- Implemented branch copy via two-step bookmark creation
- All 13 existing commit/branch tests still pass

## Task Commits

Each task was committed atomically:

1. **Task 1: Extend cmd_commit.py with new flag support** - `824dea3` (feat)
2. **Task 2: Extend cmd_branch.py with new flag support** - `12b290a` (feat)

## Files Created/Modified
- `cmd_commit.py` - Extended with COMM-01 through COMM-08 flag handling
- `cmd_branch.py` - Extended with BRAN-01 through BRAN-09 flag handling

## Decisions Made
- **sl amend -e behavior:** sl amend defaults to reusing message (like git --no-edit). Added -e flag by default to match git's editor behavior, omit when --no-edit present.
- **signoff implementation:** Used custom trailer appending instead of sl config-based approach for cleaner control.
- **branch copy two-step:** No sl bookmark --copy exists, so implemented as: get commit hash via template, create new bookmark at that hash.
- **branch verbose template:** Used `{bookmark}: {node|short} {desc|firstline}` template instead of sl -v flag which has different semantics.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Commit and branch flag implementations complete
- Ready for Phase 25-02: E2E tests for commit and branch flags
- All existing tests continue to pass
