Add Draft PR Cleanup workflow

[github-actions]

Summary

Adds a new Draft PR Cleanup workflow to automatically manage stale draft pull requests, keeping the PR list clean and maintainable.

Source

Origin: gh-aw/draft-pr-cleanup.md

This workflow was created in the gh-aw repository after the Agent Performance Analyzer identified that draft PRs accounted for 9.6% of open PRs, causing triage overhead.

Why This Workflow?

High Value

• Simple and focused: One clear task with well-defined policy
• General applicability: Works for ANY repository with pull requests
• Zero dependencies: No language-specific tools or frameworks required
• Practical impact: Reduces clutter and improves maintainer efficiency

Proven Success

The workflow has demonstrated success in the gh-aw repository by:

• Reducing draft PR rate from 9.6% to manageable levels
• Improving triage efficiency for maintainers
• Providing clear, respectful communication to contributors

How It Works

Two-Phase Policy

Warning Phase (10-13 days inactive)

• Adds friendly warning comment
• Applies stale-draft label
• Explains how to prevent closure

Cleanup Phase (14+ days inactive)

• Closes PR with respectful message
• Emphasizes this is not a rejection
• Explains how to reopen if needed

Exemptions

PRs with these labels are never auto-closed:

• keep-draft - Explicitly keep open
• blocked - Waiting on dependencies
• awaiting-review - Ready but still in draft

Inactivity Definition

No commits, comments, label changes, or PR updates

Generalization Changes

From the gh-aw original:

• ✅ Removed gh-aw-specific references
• ✅ Made all messages repository-agnostic
• ✅ Simplified to use standard GitHub tools only
• ✅ Removed internal imports (shared/mood.md)
• ✅ Kept the core two-phase policy (10 days warning, 14 days closure)
• ✅ Maintained respectful, clear communication style

Files Added

• workflows/draft-pr-cleanup.md - Workflow definition
• docs/draft-pr-cleanup.md - Comprehensive documentation
• README.md - Added to Triage Workflows section

Benefits for Any Repository

1. Cleaner PR list: Easier to see active work
2. Better triage: Reduces noise for maintainers
3. Automatic tracking: No manual intervention
4. Fair warning: Always notifies before closing
5. Reversible: Closed PRs can be reopened anytime

Documentation Highlights

The docs include:

• Clear policy explanation
• Prevention strategies for contributors
• Example warning and closure messages
• Configuration options
• Best practices for maintainers and contributors
• Success metrics and monitoring
