Update Graphite Stack

Graphite Stack Updater

Automate Graphite PR stack updates by resolving comments and syncing PRs.

Note: This skill requires Graphite CLI (gt) as PR stacking is a Graphite-specific concept. For standard Git workflows, use the resolve-pr-issues skill to address PR comments on individual PRs.

When to Activate

• User has a Graphite stack with comments
• Multiple PRs need updating
• Stack sync needed after changes
• Review comments to address
• User mentions "gt stack" or "update stack"

Prerequisites

• Graphite CLI installed: npm install -g @withgraphite/graphite-cli@latest
• Repository initialized with Graphite: gt repo init
• Existing Graphite stack with PRs to update

Why Graphite-only? This skill manages PR stacks, which is a Graphite-specific workflow. For standard Git workflows, use resolve-pr-issues to address comments on individual PRs.

What It Does

1. Analyze Stack: Check structure with gt stack
2. Find Comments: Identify PRs with unresolved feedback
3. Address Feedback: Help resolve comments
4. Update Stack: Use Graphite commands to sync
5. Verify: Ensure all upstack PRs remain in sync

Execution Flow

For each PR with comments (bottom to top):

1. Review the feedback
2. Make necessary changes
3. Run gt modify --no-verify to amend
4. Execute gt submit --stack --update-only to sync upstack
5. Continue until all PRs updated

Key Graphite Commands Used

gt stack           # View current stack
gt modify          # Amend current commit
gt submit --stack  # Update all PRs in stack

Options

• Process entire stack or specific PR range
• Filter by comment type (style, logic, performance)
• Dry-run mode to preview changes
• Auto-commit vs manual review mode

Output

Progress summary with:

• Number of PRs updated
• Comments resolved per PR
• Remaining unresolved items
• Stack synchronization status
