# rebase-latest-main

A skill that walks the agent through fetching origin/main, rebasing the current branch and resolving conflicts. Handy when your branch has drifted behind main.

## What it does

The skill lays out a git procedure step by step. First the agent checks the current branch and looks for uncommitted changes. If any exist, it either commits them or asks you how to proceed — commit, stash or abort.

Then come `git fetch origin main` and `git rebase origin/main`. On conflicts the agent lists files with `git diff --name-only --diff-filter=U`, reads each one, compares both sides and stages the fix with `git add <resolved-file>` before continuing the rebase. If it cannot sort things out, it shows the conflict markers and waits for your call; `git rebase --abort` rolls back.

After a clean rebase the skill pushes with `git push --force-with-lease`, which is safer than `--force` because it will not clobber someone else's work. Worth knowing: if your workflow forbids force-pushing a shared branch, you skip that step by hand. At the end the agent reports how many commits moved and which conflicts it closed.

```bash
npx skills add dyoshikawa/rulesync --skill rebase-latest-main -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/rebase-latest-main/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rebase-latest-main/

### Codex

```bash
npx skills add dyoshikawa/rulesync --skill rebase-latest-main -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/rebase-latest-main/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill rebase-latest-main -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/rebase-latest-main/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

## When to use it
- pull the latest origin/main into your branch
- work through rebase conflicts
- check for uncommitted changes before rebasing
- roll back a failed rebase with git rebase --abort
- update the remote branch after moving commits

## Example prompts
- rebase onto the latest main
- update my branch with the latest main
- sync my branch with upstream

# Rebase Latest Main

Fetch the latest `origin/main` and rebase it onto the current working branch.

## Step 1: Verify Current State

1. Check the current branch:

   ```bash
   git branch --show-current
   ```

2. Ensure there are no uncommitted changes:

   ```bash
   git status --porcelain
   ```

   If there are uncommitted changes, either:
   - Commit them first, or
   - Ask the user how to proceed (commit, stash, or abort)

## Step 2: Fetch Latest Changes

Fetch the latest changes from the remote:

```bash
git fetch origin main
```

## Step 3: Rebase onto origin/main

Start the rebase:

```bash
git rebase origin/main
```

### If rebase succeeds without conflicts:

Proceed to Step 5.

### If conflicts occur:

1. Identify conflicting files:

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

2. For each conflicting file:
   - Read the file content to understand the conflict
   - Analyze both versions (HEAD and origin/main)
   - Resolve the conflict by choosing the appropriate changes or merging them
   - Stage the resolved file:
     ```bash
     git add <resolved-file>
     ```

3. Continue the rebase:

   ```bash
   git rebase --continue
   ```

4. Repeat until all conflicts are resolved and rebase is complete.

## Step 4: Handle Rebase Failure

If unable to resolve conflicts automatically:

- Show the conflicting files and conflict markers to the user
- Ask for guidance on how to resolve
- If the user wants to abort:
  ```bash
  git rebase --abort
  ```

## Step 5: Push Changes

After successful rebase, force push to update the remote branch:

```bash
git push --force-with-lease
```

Note: `--force-with-lease` is safer than `--force` as it prevents overwriting others' work.

## Step 6: Report Result

Summarize the operation:

1. Number of commits rebased
2. Any conflicts that were resolved
3. Confirmation that the branch is now up-to-date with origin/main
