## 🎯 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

## 🚀 Quick Start

```bash
pip install prgenius-core

# Analyze PR
python3 -m prgenius analyze "feat: add feature" --repo org/repo --body "Fixes #123"

# Coach (pass/fail)
python3 -m prgenius coach "feat: add feature" --repo org/repo

# Triage (policy check)
python3 -m prgenius triage "docs: typo" --repo org/repo --diff-stat "docs/faq.md | 3 ++-"

python3 -m prgenius status --author zsxh1990 --format json --save-snapshot

# Profile writeback suggestions (dry-run)
python3 -m prgenius profile writeback --author zsxh1990
```

## 🤖 GitHub Action

Use PR Genius as a GitHub Action in any repo:

```yaml
# .github/workflows/pr-genius.yml
name: PR Genius Check
on:
  pull_request:
    types: [opened, synchronize]

permissions:
  contents: read
  issues: write   # required when comment_mode != never (post/update PR comment)

jobs:
  pr-genius:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: zsxh1990/pr-genius@v1
        id: pr-genius
        with:
          title: ${{ github.event.pull_request.title }}
          repo: ${{ github.repository }}
          body: ${{ github.event.pull_request.body }}
          pr_number: ${{ github.event.pull_request.number }}
          comment_mode: always   # never | high_risk | always — post full analysis as a PR comment
```

`comment_mode` controls whether the full analysis is posted as a visible PR
comment (mirrors pr-agent's `/review`):

- `never` — do not post (default when unset and `comment_on_high_risk` is false)
- `high_risk` — post only when the risk tier is `high_risk`
- `always` — post on every run; existing comments are updated in place (no spam)

> **Legacy**: `comment_on_high_risk: true` is still supported and behaves like
> `comment_mode: high_risk`.

### Version Auto-Update

- **`@v1`** — Always points to the latest `v1.x.x` release (recommended)
- **`@v1.9.0`** — Pinned to specific version (for reproducibility)
- **`@main`** — Latest development version (not recommended for production)

The `v1` tag is automatically updated when a new version is published to PyPI.
