+# Pull Request Workflow
+
+Execute via `git-manager` subagent.
+
+## Variables
+- TO_BRANCH: target (defaults to `main`)
+- FROM_BRANCH: source (defaults to current branch)
+
+## CRITICAL: Use REMOTE diff
+PRs based on remote branches. Local diff includes unpushed changes.
+
+## Tool 1: Sync + Analyze
+
+**IMPORTANT: Always merge `main` (or any default branch) to current branch first.**
+
+```bash
+git fetch origin && \
+git push -u origin HEAD 2>/dev/null || true && \
+BASE=${BASE_BRANCH:-main} && \
+HEAD=$(git rev-parse --abbrev-ref HEAD) && \
+echo "=== PR: $HEAD → $BASE ===" && \
+echo "=== COMMITS ===" && \
+git log origin/$BASE...origin/$HEAD --oneline && \
+echo "=== FILES ===" && \
+git diff origin/$BASE...origin/$HEAD --stat
+```
+
+**If "Branch not on remote":** Push first, retry.
+
+## Tool 2: Generate Content
+**Title:** Conventional commit format, <72 chars, NO version numbers
+**Body:** Summary bullets + Test plan checklist
+
+## Tool 3: Create PR
+```bash
+gh pr create --base $BASE --head $HEAD --title "..." --body "$(cat <<'EOF'
+## Summary
+- Bullet points
+
+## Test plan
+- [ ] Test item
+EOF
+)"
+```
+
+## DO NOT use (local comparison)
+- ❌ `git diff main...HEAD`
+- ❌ `git diff --cached`
+- ❌ `git status`
+
+## Error Handling
+
+| Error | Action |
+|-------|--------|
+| Branch not on remote | `git push -u origin HEAD`, retry |
+| Empty diff | Warn: "No changes for PR" |
+| Push rejected | `git pull --rebase`, resolve, push |
+| No upstream | `git push -u origin HEAD` |
