pr-review

name	pr-review
description	Reviews all open pull requests on the MockServer GitHub repository and produces a structured report. Classifies PRs as mergeable, needs-work, stale/out-of-date, or duplicate. Use when the user says "review PRs", "PR report", "check pull requests", "PR status", "open PRs", or "duplicate PRs".

Pull Request Review Report

Analyze all open pull requests on the MockServer GitHub repository and produce a comprehensive report covering mergeability, staleness, actionability, and duplicates.

Prerequisites

• GITHUB_TOKEN environment variable set with a GitHub personal access token that has repo scope for github.com, OR
• gh CLI authenticated to github.com (gh auth login --hostname github.com)

Check which is available:

if [ -n "$GITHUB_TOKEN" ]; then
  echo "Using GITHUB_TOKEN"
elif gh auth status --hostname github.com 2>/dev/null; then
  echo "Using gh CLI"
else
  echo "ERROR: Set GITHUB_TOKEN or run: gh auth login --hostname github.com"
  exit 1
fi

Repository

• Owner: mock-server
• Repo: mockserver
• API Base: https://api.github.com/repos/mock-server/mockserver-monorepo

Step 1: Fetch All Open PRs

Fetch all open PRs with full metadata. Paginate if there are more than 100:

# Using GITHUB_TOKEN
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/pulls?state=open&per_page=100&page=1" \
  | jq '[.[] | {
    number,
    title,
    user: .user.login,
    created_at,
    updated_at,
    head_ref: .head.ref,
    head_sha: .head.sha,
    base_ref: .base.ref,
    mergeable_state: .mergeable_state,
    draft: .draft,
    labels: [.labels[].name],
    body: (.body // "" | .[0:200])
  }]'

# Using gh CLI (if authenticated to github.com)
gh pr list --repo mock-server/mockserver-monorepo --state open --limit 100 \
  --json number,title,author,createdAt,updatedAt,headRefName,baseRefName,isDraft,labels,mergeable,reviewDecision

Step 2: Get Detailed PR Info

For each PR, fetch merge status and review details:

# Merge status (requires individual PR fetch for mergeable field)
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/pulls/{number}" \
  | jq '{number, mergeable, mergeable_state, rebaseable, maintainer_can_modify, changed_files, additions, deletions}'

# Reviews
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/pulls/{number}/reviews" \
  | jq '[.[] | {user: .user.login, state, submitted_at}]'

# CI status checks
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/commits/{head_sha}/status" \
  | jq '{state, total_count, statuses: [.statuses[] | {context, state, description}]}'

# Check runs (GitHub Actions)
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/commits/{head_sha}/check-runs" \
  | jq '{total_count, check_runs: [.check_runs[] | {name, status, conclusion}]}'

Step 3: Check Base Branch Freshness

Determine if each PR is up-to-date with its base branch:

# Compare base branch with PR head
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/compare/{base_ref}...{head_sha}" \
  | jq '{behind_by, ahead_by, status}'

• behind_by > 0 means the PR is out-of-date with the base branch
• status: "diverged" means both branches have new commits

Step 4: Classify Each PR

Apply these classifications in order (first match wins):

Category: STALE

• Last updated more than 6 months ago
• No activity (comments, commits, reviews) in 6+ months

Category: OUT_OF_DATE

• PR is behind the base branch (behind_by > 0)
• May have merge conflicts (mergeable: false)

Category: MERGEABLE

• mergeable: true
• All CI checks pass (status: success)
• Has at least one approving review, OR is from a bot (dependabot, snyk)
• Not a draft

Category: NEEDS_WORK

• Has requested changes in reviews
• CI checks are failing
• Is a draft PR
• Has merge conflicts but is recently active

Category: BLOCKED

• Waiting on external dependency
• Explicitly labeled as blocked

Step 5: Detect Duplicates

Compare PRs for potential duplicates using these signals:

1. Same files changed: PRs modifying the same set of files
2. Similar titles: PRs with similar titles (e.g., both mention "snyk", "dependabot", same dependency)
3. Same author + same dependency: Multiple Snyk/Dependabot PRs for the same package
4. Overlapping branches: PRs targeting the same files with similar diffs

# Get files changed per PR
curl -sH "Authorization: token $GITHUB_TOKEN" \
  -H "Accept: application/vnd.github.v3+json" \
  "https://api.github.com/repos/mock-server/mockserver-monorepo/pulls/{number}/files" \
  | jq '[.[] | .filename]'

Group PRs by:

• Dependencies they update (parse from title/body: "bump X from Y to Z")
• Files they modify
• Author (bot PRs from same bot often overlap)

Step 6: Generate Report

Produce a structured report with these sections:

Output Format

# MockServer PR Review Report

**Generated:** {date}
**Open PRs:** {count}
**Repository:** mock-server/mockserver-monorepo

## Summary

| Category | Count | Action |
|----------|-------|--------|
| Mergeable | N | Ready to merge |
| Needs Work | N | Requires changes or CI fixes |
| Out of Date | N | Needs rebase/update |
| Stale | N | Consider closing |
| Duplicates | N groups | Consolidate |

## Mergeable PRs (Ready to Merge)

| PR | Title | Author | Age | CI | Reviews |
|----|-------|--------|-----|-----|---------|
| #N | title | author | Xd | pass | approved |

## PRs Needing Work

| PR | Title | Author | Issue | Last Activity |
|----|-------|--------|-------|---------------|
| #N | title | author | CI failing / changes requested | Xd ago |

## Out-of-Date PRs

| PR | Title | Author | Behind By | Last Updated | Has Conflicts |
|----|-------|--------|-----------|--------------|---------------|
| #N | title | author | N commits | date | yes/no |

## Stale PRs (Recommend Closing)

| PR | Title | Author | Last Activity | Reason |
|----|-------|--------|---------------|--------|
| #N | title | author | date | No activity for X months |

## Potential Duplicates

### Group 1: {description}
| PR | Title | Author | Files Changed |
|----|-------|--------|---------------|
| #N | title | author | file1, file2 |
| #M | title | author | file1, file2 |
**Recommendation:** Keep #N (newer/more complete), close #M

## Recommendations

1. **Merge immediately:** List PR numbers
2. **Close as stale:** List PR numbers with reasoning
3. **Consolidate duplicates:** Which to keep and which to close
4. **Request updates:** Which PRs need author action

Notes

• Bot PRs (Dependabot, Snyk) often accumulate and become stale; prioritize identifying these
• PRs that only modify pom.xml for version bumps are often duplicated by multiple bots
• Check if a stale PR's changes have already been superseded by a newer PR or direct commit
• For dependency update PRs, check if the dependency was already updated in the main branch
