🎯 What is PR Genius?

PR Genius is not a PR dashboard. It's an Outbound PR CRM for professional OSS contributors and AI agents:

Manage PRs you've submitted to other repos — when to fix CI, rebase, wait, ping, or abandon.

Capability	gh CLI	PR Genius
Cross-repo PR list	✅	✅
Status classification	❌	✅ (9 states)
Stale detection	❌	✅
Action suggestions	❌	✅
Repo-specific policy	❌	✅
Snapshot & transitions	❌	✅

Status heartbeat runs daily via cron, auto-detecting:

• 🔴 NEEDS_REBASE / CI_FAILING — fix immediately
• 🟡 STALE_REVIEW — ping after threshold
• 🟡 STALE_NO_REVIEW — consider abandoning
• 🟢 CLEAN / WAITING — continue waiting
