# Updating Skills from Upstream

## Overview

Pull and merge upstream changes from obra/superpowers-skills into your local skills repository while preserving your personal modifications.

**Announce at start:** "I'm using the Updating Skills skill to sync with upstream."

## Prerequisites

Your skills repo must have a tracking branch configured. The plugin sets this up automatically (either as a fork with `origin` remote, or with an `upstream` remote).

## The Process

### Step 1: Check Current Status

Run:
```bash
cd ~/.config/superpowers/skills
git status
```

**If working directory is dirty:** Proceed to Step 2 (stash changes)
**If clean:** Skip to Step 3

### Step 2: Stash Uncommitted Changes (if needed)

Run:
```bash
git stash push -m "Temporary stash before upstream update"
```

Record: Whether changes were stashed (you'll need to unstash later)

### Step 3: Determine Tracking Remote and Fetch

First, detect which remote to use:
```bash
TRACKING_REMOTE=$(git rev-parse --abbrev-ref --symbolic-full-name @{u} 2>/dev/null | cut -d'/' -f1 || echo "")
```

Then fetch from the appropriate remote:
```bash
if [ -n "$TRACKING_REMOTE" ]; then
    git fetch "$TRACKING_REMOTE" 2>/dev/null || true
else
    git fetch upstream 2>/dev/null || git fetch origin 2>/dev/null || true
fi
```

Expected: Fetches latest commits from the tracking remote (or falls back to upstream/origin)

### Step 4: Check What's New

Run:
```bash
git log HEAD..@{u} --oneline
```

Show user: List of new commits being pulled

Note: `@{u}` refers to the upstream tracking branch for your current branch

### Step 5: Merge Changes

First, try a fast-forward merge (cleanest option):
```bash
git merge --ff-only @{u}
```

**If fast-forward succeeds:** Skip to Step 7 (no conflicts possible with fast-forward)
**If fast-forward fails:** Your branch has diverged. Try regular merge:
```bash
git merge @{u}
```

**If merge succeeds cleanly:** Proceed to Step 7
**If conflicts occur:** Proceed to conflict resolution

### Step 6: Handle Merge Conflicts (if any)

If conflicts:
1. Run `git status` to see conflicted files
2. For each conflict, explain to user what changed in both versions
3. Ask user which version to keep or how to merge
4. Edit files to resolve
5. Run `git add <resolved-file>` for each
6. Run `git commit` to complete merge

### Step 7: Unstash Changes (if stashed in Step 2)

If you stashed changes:
```bash
git stash pop
```

**If conflicts with unstashed changes:** Help user resolve them

### Step 8: Verify Everything Works

Run:
```bash
${SUPERPOWERS_SKILLS_ROOT}/skills/using-skills/find-skills
```

Expected: Skills list displays correctly

### Step 9: Announce Completion

Tell user:
- How many new commits were merged
- Whether any conflicts were resolved
- Whether their stashed changes were restored
- That skills are now up to date

## Common Issues

**"Already up to date"**: Your local repo is current, no action needed

**"fatal: no upstream configured"**: Your branch isn't tracking a remote branch. Check `git remote -v` to see available remotes, then set tracking with `git branch --set-upstream-to=<remote>/<branch>`

**Detached HEAD**: You're not on a branch. Ask user if they want to create a branch or check out main.

**Fast-forward fails, diverged branches**: Your local branch has commits that aren't in the remote. Regular merge will be needed, which may cause conflicts.

## Remember

- Always stash uncommitted work before merging
- Explain conflicts clearly to user
- Test that skills work after update
- User's local commits/branches are preserved
