resolve-conflicts（解决冲突）

Resolve Conflicts

Resolve git conflicts from any operation with proper continuation workflow.

Usage

/resolve-conflicts              # Resolve all conflicts
/resolve-conflicts path/to/file # Focus on specific file

Gotchas

• During rebase, ours/theirs semantics are INVERTED. "Ours" is the branch being rebased onto (the target), not your working branch. This causes wrong-direction resolutions if you forget.
• Lock file conflicts (package-lock.json, yarn.lock, Podfile.lock) must NEVER be manually resolved. Delete the lock file and regenerate it — manual merging produces corrupt files.

Workflow

Step 1: Detect Operation Type

Use Glob to check for these sentinel files in the .git/ directory:

• .git/MERGE_HEAD → Merge
• .git/rebase-merge or .git/rebase-apply → Rebase
• .git/CHERRY_PICK_HEAD → Cherry-pick
• .git/REVERT_HEAD → Revert
• None of the above → Stash (or manual conflict)

Step 2: List Conflicted Files

git diff --name-only --diff-filter=U

Then run git status to see the full conflict status for each file.

Conflict markers in git status:

• UU - Both modified (most common)
• AA - Both added
• DD - Both deleted
• AU/UA - Added by us/them, modified by other
• DU/UD - Deleted by us/them, modified by other

Step 3: Analyze Each Conflict

Read the conflicted file and identify:

<<<<<<< HEAD (or ours)
Current branch changes
=======
Incoming changes
>>>>>>> branch-name (or theirs)

For rebase conflicts: "Ours" is the branch being rebased onto, "theirs" is the commit being replayed. This is inverted from merge!

Step 4: Apply Resolution

Edit the file to:

1. Remove conflict markers (<<<<<<<, =======, >>>>>>>)
2. Keep the correct code
3. Ensure the result is syntactically valid

Step 5: Print Next Steps

Do NOT run git commands yourself. Print the commands the user needs to run:

Run these commands to complete the resolution:

git add <resolved-files>
<continue_command based on operation type>

Output Format

## Conflict Resolution: {MERGE|REBASE|CHERRY-PICK|REVERT}

### Situation
- Operation: {type}
- Current branch: {branch}
- Incoming: {branch/commit}

### Conflicted Files ({count})
| File | Type | Complexity |
|------|------|------------|
| {path} | UU | {simple/moderate/complex} |

### Next Steps

Run these commands to complete the resolution:
1. `git add {files}`
2. `{continue_command}`

Or to abort:
- `{abort_command}`

Examples

Merge conflict on auth logic -- merge both sides:

/resolve-conflicts src/auth/session.ts

Detects a merge operation, reads the conflict markers in the session file, and determines that both sides added complementary validation checks. Recommends merging both changes together and produces a clean resolution that includes both validations.

Rebase conflict with inverted ours/theirs:

/resolve-conflicts

Detects a rebase operation and reminds that ours/theirs semantics are inverted during rebase. Walks through each conflicted file, explains what the rebased commit intended versus the target branch state, resolves the conflicts in the files, and prints the commands to run (git add + git rebase --continue).

Guidelines

• Understand both sides before resolving - don't blindly pick one
• Check for semantic conflicts - code may compile but logic is broken
• Review the full file - changes outside markers may be affected
• Test after resolving - run tests if available
• For rebase: remember ours/theirs are inverted from merge

Common Patterns

Lock File Conflicts (package-lock.json, yarn.lock)

Regenerate rather than manually resolve. Tell the user to run:

git checkout --theirs package-lock.json  # or --ours
npm install  # regenerates lock file
git add package-lock.json

Auto-generated Files

Accept one version and regenerate. Tell the user to run:

git checkout --theirs <file>
# Run generation command
git add <file>

Both Added Same File Differently

Usually keep one and incorporate changes from other manually.

Deleted vs Modified

Decide: should file exist or not? If yes, keep modified. If no, remove. Tell the user to run the appropriate command:

# Keep the file (accept modification)
git add <file>

# Delete the file
git rm <file>
