File contents

PR Reviewer

Automated code review for GitHub pull requests. Analyzes diffs for security issues, error handling gaps, style problems, and test coverage.

Prerequisites

gh CLI installed and authenticated (gh auth status)
Repository access (read at minimum, write for posting comments)
Optional: golangci-lint for Go linting, ruff for 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-unreviewed

Configuration

Set these environment variables or the script auto-detects from the current git repo:

PR_REVIEW_REPO — GitHub repo in owner/repo format (default: detected from gh 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 SHAs
PR_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
fi

Extending

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'))
