CoStrict Conflict Resolution Skill

When to Use This Skill

Use this skill when the task involves:

• Resolving merge conflicts for a specific pull request
• Rebasing a branch that has conflicts with the target branch
• Understanding and analyzing conflicting code changes
• Making intelligent decisions about which changes to keep, merge, or discard
• Using git history to inform conflict resolution decisions

When NOT to Use This Skill

Do NOT use this skill when:

• There are no merge conflicts to resolve
• The task is about general code review without conflicts
• You're working on fresh code without any merge scenarios

Workflow Overview

This skill resolves merge conflicts by analyzing git history, commit messages, and code changes to make intelligent resolution decisions. Given a PR number (e.g., "#123"), it handles the entire conflict resolution process.

Initialization Steps

Step 1: Parse PR Number

Extract the PR number from input like "#123" or "PR #123". Validate that a PR number was provided.

Step 2: Fetch PR Information

gh pr view [PR_NUMBER] --json title,body,headRefName,baseRefName

Get PR title and description to understand the intent and identify the source and target branches.

Step 3: Checkout PR Branch and Prepare for Rebase

gh pr checkout [PR_NUMBER] --force
git fetch origin main
GIT_EDITOR=true git rebase origin/main

• Force checkout the PR branch to ensure clean state
• Fetch the latest main branch
• Attempt to rebase onto main to reveal conflicts
• Use GIT_EDITOR=true to ensure non-interactive rebase

Step 4: Check for Merge Conflicts

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

Identify files with merge conflicts (marked with 'UU') and create a list of files that need resolution.

Main Workflow Phases

Phase 1: Conflict Analysis

Analyze each conflicted file to understand the changes:
