Revert Track

Revert changes by logical work unit with full git awareness. Supports reverting entire tracks, specific phases, or individual tasks.

Use this skill when

• Working on revert track tasks or workflows
• Needing guidance, best practices, or checklists for revert track

Do not use this skill when

• The task is unrelated to revert track
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Pre-flight Checks

1. Verify Conductor is initialized:
2. Check conductor/tracks.md exists

3. If missing: Display error and suggest running /conductor:setup first

4. Verify git repository:

5. Run git status to confirm git repo
6. Check for uncommitted changes

7. If uncommitted changes exist:

   ```
   WARNING: Uncommitted changes detected

   Files with changes:
   {list of files}

   Options:
   1. Stash changes and continue
   2. Commit changes first
   3. Cancel revert
   ```

8. Verify git is clean enough to revert:

9. No merge in progress
10. No rebase in progress
11. If issues found: Halt and explain resolution steps

Target Selection

If argument provided:

Parse the argument format:

Full track: {trackId}

• Example: auth_20250115
• Reverts all commits for the entire track

Specific phase: {trackId}:phase{N}

• Example: auth_20250115:phase2
• Reverts commits for phase N and all subsequent phases

Specific task: {trackId}:task{X.Y}

• Example: auth_20250115:task2.3
• Reverts commits for task X.Y only

If no argument:

Display guided selection menu:

Commit Discovery

For Task Revert

1. Search git log for task-specific commits:

bash git log --oneline --grep="{trackId}" --grep="Task {X.Y}" --all-match

1. Also find the plan.md update commit:

bash git log --oneline --grep="mark task {X.Y} complete" --grep="{trackId}" --all-match

1. Collect all matching commit SHAs

For Phase Revert

1. Determine task range for the phase by reading plan.md
2. Search for all task commits in that phase:

bash git log --oneline --grep="{trackId}" | grep -E "Task {N}\.[0-9]"

1. Find phase verification commit if exists
2. Find all plan.md update commits for phase tasks
3. Collect all matching commit SHAs in chronological order

For Full Track Revert

1. Find ALL commits mentioning the track:

bash git log --oneline --grep="{trackId}"

1. Find track creation commits:

bash git log --oneline -- "conductor/tracks/{trackId}/"

1. Collect all matching commit SHAs in chronological order

Execution Plan Display

Before any revert operations, display full plan:

================================================================================
                           REVERT EXECUTION PLAN
================================================================================

Target: {description of what's being reverted}

Commits to revert (in reverse chronological order):
  1. abc1234 - feat: add chart rendering (dashboard_20250112)
  2. def5678 - chore: mark task 2.3 complete (dashboard_20250112)
  3. ghi9012 - feat: add data hooks (dashboard_20250112)
  4. jkl3456 - chore: mark task 2.2 complete (dashboard_20250112)

Files that will be affected:
  - src/components/Dashboard.tsx (modified)
  - src/hooks/useData.ts (will be deleted - was created in these commits)
  - conductor/tracks/dashboard_20250112/plan.md (modified)

Plan updates:
  - Task 2.2: [x] -> [ ]
  - Task 2.3: [~] -> [ ]

================================================================================
                              !! WARNING !!
================================================================================

This operation will:
- Create {N} revert commits
- Modify {M} files
- Reset {P} tasks to pending status

This CANNOT be easily undone without manual intervention.

================================================================================

Type 'YES' to proceed, or anything else to cancel:

CRITICAL: Require explicit 'YES' confirmation. Do not proceed on 'y', 'yes', or enter.

Revert Execution

Execute reverts in reverse chronological order (newest first):

Executing revert plan...

[1/4] Reverting abc1234...
      git revert --no-edit abc1234
      ✓ Success

[2/4] Reverting def5678...
      git revert --no-edit def5678
      ✓ Success

[3/4] Reverting ghi9012...
      git revert --no-edit ghi9012
      ✓ Success

[4/4] Reverting jkl3456...
      git revert --no-edit jkl3456
      ✓ Success

On Merge Conflict

If any revert produces a merge conflict:

================================================================================
                           MERGE CONFLICT DETECTED
================================================================================

Conflict occurred while reverting: {sha} - {message}

Conflicted files:
  - src/components/Dashboard.tsx

Options:
1. Show conflict details
2. Abort revert sequence (keeps completed reverts)
3. Open manual resolution guide

IMPORTANT: Reverts 1-{N} have been completed. You may need to manually
resolve this conflict before continuing or fully undo the revert sequence.

Select option:

HALT immediately on any conflict. Do not attempt automatic resolution.

Plan.md Updates

After successful git reverts, update plan.md:

1. Read current plan.md
2. For each reverted task, change marker:
3. [x] -> [ ]
4. [~] -> [ ]
5. Write updated plan.md
6. Update metadata.json:
7. Decrement tasks.completed
8. Update status if needed
9. Update updated timestamp

Do NOT commit plan.md changes - they are part of the revert operation

Track Status Updates

If reverting entire track:

• In tracks.md: Change [x] or [~] to [ ]
• Consider offering to delete the track directory entirely

If reverting to incomplete state:

• In tracks.md: Ensure marked as [~] if partially complete, [ ] if fully reverted

Verification

After revert completion:

================================================================================
                           REVERT COMPLETE
================================================================================

Summary:
  - Reverted {N} commits
  - Reset {P} tasks to pending
  - {M} files affected

Git log now shows:
  {recent commit history}

Plan.md status:
  - Task 2.2: [ ] Pending
  - Task 2.3: [ ] Pending

================================================================================

Verify the revert was successful:
  1. Run tests: {test command}
  2. Check application: {relevant check}

If issues are found, you may need to:
  - Fix conflicts manually
  - Re-implement the reverted tasks
  - Use 'git revert HEAD~{N}..HEAD' to undo the reverts

================================================================================

Safety Rules

1. NEVER use git reset --hard - Only use git revert
2. NEVER use git push --force - Only safe push operations
3. NEVER auto-resolve conflicts - Always halt for human intervention
4. ALWAYS show full plan - User must see exactly what will happen
5. REQUIRE explicit 'YES' - Not 'y', not enter, only 'YES'
6. HALT on ANY error - Do not attempt to continue past failures
7. PRESERVE history - Revert commits are preferred over history rewriting

Edge Cases

Track Never Committed

No commits found for track: {trackId}

The track exists but has no associated commits. This may mean:
- Implementation never started
- Commits used different format

Options:
1. Delete track directory only
2. Cancel

Commits Already Reverted

Some commits appear to already be reverted:
  - abc1234 was reverted by xyz9876

Options:
1. Skip already-reverted commits
2. Cancel and investigate

Remote Already Pushed

WARNING: Some commits have been pushed to remote

Commits on remote:
  - abc1234 (origin/main)
  - def5678 (origin/main)

Reverting will create new revert commits that you'll need to push.
This is the safe approach (no force push required).

Continue with revert? (YES/no):

Undo the Revert

If user needs to undo the revert itself:

To undo this revert operation:

  git revert HEAD~{N}..HEAD

This will create new commits that restore the reverted changes.

Alternatively, if not yet pushed:
  git reset --soft HEAD~{N}
  git checkout -- .

(Use with caution - this discards the revert commits)
