Stale PR Reminder

Scan repositories for stale Pull Requests and generate a prioritized action report.

What is a "Stale PR"?

A stale PR is a Pull Request that:

• Has been open for a long time without updates
• Has not received reviewer attention
• Has merge conflicts that haven't been resolved

Staleness Levels

Steps

Step 1: Fetch Open PRs

Call list_repo_pulls to retrieve all open PRs:

INPUT:
  - owner: repository owner
  - repo: repository name
  - state: "open"
  - sort: "created"
  - direction: "asc"
  - per_page: 100

Step 2: Get PR Details

For each PR, call get_pull_detail:

EXTRACT:
  - number: PR number
  - title: PR title
  - user.login: author username
  - created_at: creation timestamp
  - updated_at: last update timestamp
  - mergeable: false = has conflicts
  - draft: is draft PR

Step 3: Get Comments (Optional)

Call list_pull_comments to check review activity:

ANALYZE:
  - has_reviewer_comments: any comment from non-author
  - last_comment_date: most recent comment timestamp

Step 4: Calculate Staleness

No code execution needed. The AI can parse timestamps directly.

Today's date: 2026-03-17

For each PR:

1. Parse created_at (format: YYYY-MM-DDTHH:MM:SSZ, e.g., 2026-01-15T10:30:00Z)
2. Parse updated_at the same way
3. Calculate days between created_at and today (2026-03-17)
4. Calculate days between updated_at and today
5. Check if mergeable: false (has conflicts)
6. Check if draft: true

Classification rules:

• critical: age > 28 days
• severe: age > 14 days AND days_since_update > 14
• moderate: age > 7 days AND no reviewer comments
• mild: age > 3 days AND days_since_update > 3
• fresh: otherwise

Step 5: Generate Report

Create a grouped report with links:

## Stale PR Report: {owner}/{repo}

### Critical (> 28 days)
| PR | Title | Age | Author |
|----|-------|-----|--------|
| [#{num}](https://gitee.com/{owner}/{repo}/pulls/{num}) | {title} | {age}d | @{author} |

### Severe (> 14 days no update)
| PR | Title | Age | Last Update |
|----|-------|-----|-------------|
| [#{num}](https://gitee.com/{owner}/{repo}/pulls/{num}) | {title} | {age}d | {days}d ago |

### Moderate (> 7 days no review)
| PR | Title | Age |
|----|-------|-----|
| [#{num}](https://gitee.com/{owner}/{repo}/pulls/{num}) | {title} | {age}d |

### Summary
- Critical: {count}
- Severe: {count}
- Moderate: {count}
- Fresh: {count}

Usage Examples

Example 1: Basic Check

User: "Check for stale PRs in myrepo"

AI: Scanning myrepo...
Found 10 open PRs:
- 2 Critical (> 28 days)
- 3 Severe (> 14 days)
- 5 Moderate (> 7 days)

[Shows report]

Example 2: Check Specific Author

User: "Are there any stale PRs from @alice?"

AI: Found 2 stale PRs from @alice:
- PR #42: 25 days old, needs rebase
- PR #45: 12 days old, waiting for review

Notes

• Be diplomatic when mentioning stale PRs
• Exclude bot PRs (dependabot, renovate) by default
• Respect "wip", "draft", "on-hold" labels
