PR Reviewer
Automated code review for GitHub pull requests. Analyzes diffs for security issues, error handling gaps, style problems, and test coverage.
Prerequisites
ghCLI installed and authenticated (gh auth status)- Repository access (read at minimum, write for posting comments)
- Optional:
golangci-lintfor Go linting,rufffor Python linting
Quick Start
# Review all open PRs in current repo
scripts/github/pr-reviewer.sh check
# Review a specific PR
scripts/github/pr-reviewer.sh review 42
# Post review as GitHub comment
scripts/github/pr-reviewer.sh post 42
# Check status of all open PRs
scripts/github/pr-reviewer.sh status
# List unreviewed PRs (useful for heartbeat/cron integration)
scripts/github/pr-reviewer.sh list-unreviewedConfiguration
Set these environment variables or the script auto-detects from the current git repo:
PR_REVIEW_REPO— GitHub repo inowner/repoformat (default: detected fromgh repo view)PR_REVIEW_DIR— Local checkout path for lint (default: git root of cwd)PR_REVIEW_STATE— State file path (default:./data/pr-reviews.json)PR_REVIEW_OUTDIR— Report output directory (default:./data/pr-reviews/)
Directories Written
PR_REVIEW_STATE(default:./data/pr-reviews.json) — Tracks reviewed PRs and their HEAD SHAsPR_REVIEW_OUTDIR(default:./data/pr-reviews/) — Markdown review reports
What It Checks
| Category | Icon | Examples |
|---|---|---|
| Security | 🔴 | Hardcoded credentials, AWS keys, secrets in code |
| Error Handling | 🟡 | Discarded errors (Go _ :=), bare except: (Python), unchecked Close() |
| Risk | 🟠 | panic() calls, process.exit() |
| Style | 🔵 | fmt.Print/print()/console.log in prod, very long lines |
| TODOs | 📝 | TODO, FIXME, HACK, XXX markers |
| Test Coverage | 📊 | Source files changed without corresponding test changes |
Smart Re-Review
Tracks HEAD SHA per PR. Only re-reviews when new commits are pushed. Use review <PR#> to force re-review.
Report Format
Reports are saved as markdown files in the output directory. Each report includes:
- PR metadata (author, branch, changes)
- Commit list
- Changed file categorization by language/type
- Automated diff findings with file, line, category, and context
- Test coverage analysis
- Local lint results (when repo is checked out locally)
- Summary verdict: 🔴 SECURITY / 🟡 NEEDS ATTENTION / 🔵 MINOR NOTES / ✅ LOOKS GOOD
Heartbeat/Cron Integration
Add to a periodic check (heartbeat, cron job, or CI):
UNREVIEWED=$(scripts/github/pr-reviewer.sh list-unreviewed)
if [ -n "$UNREVIEWED" ]; then
scripts/github/pr-reviewer.sh check
fiExtending
The analysis patterns in the script are organized by language. Add new patterns by appending to the relevant pattern list in the analyze_diff() function:
# Add a new Go pattern
go_patterns.append((r'^\+.*os\.Exit\(', 'RISK', 'Direct os.Exit() — consider returning error'))
