AI Code Review

AI Code Review Skill

Automated code review service that combines LLM-powered diff analysis, voice-note transcription, and Discord notifications into a unified review pipeline.

Features

• LLM Code Analysis: Sends diffs to GPT-4o with structured JSON output (issues count, suggestions, approval status, summary)
• Voice Note Transcription: Transcribes review meeting recordings via OpenAI Whisper API with file validation
• Discord Notifications: Rich embed notifications with approval status, issue counts, and color-coded indicators
• URL Safety: Scheme validation prevents SSRF attacks on all fetched URLs
• Request Timeouts: All HTTP calls enforce a 30-second timeout to prevent hanging
• Structured Logging: Consistent logging throughout with logging module
• ClawHub Publishing: Built-in publish_skill() helper using the ClawHub CLI

Quick Start

# Set required environment variables
export OPENAI_API_KEY="sk-..."
export DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."  # optional

# Run a review
python src/code_review_service.py

API Reference

process_pull_request(pr_number, diff_url, voice_note_path=None)

End-to-end PR review: fetches diff, runs LLM analysis, optionally transcribes a voice note, and sends a Discord notification.

Returns a dict with keys: issues_found, suggestions, approval, summary, and optionally voice_note_transcription.

analyze_code_changes(diff_content)

Sends diff text to GPT-4o for analysis. Returns structured JSON with issues_found, suggestions, approval (approved/needs_changes/rejected), and summary.

transcribe_voice_note(audio_file_path)

Validates the audio file exists and is non-empty, then transcribes via Whisper-1. Returns the transcription text.

send_discord_notification(message, embed=None)

Posts a message (with optional rich embed) to the configured Discord webhook. Returns True on success.

publish_skill(skill_path, version)

Publishes a skill directory to ClawHub at the given version using the clawhub CLI.

Configuration

Health Check

The included scripts/healthcheck.sh monitors nginx, docker, code-review-service, and whisper-api-gateway. It auto-restarts failed services and sends Discord alerts. Disk usage warnings trigger at 80% and critical alerts at 90%.

Changelog

1.1.0

• Fixed SSRF vulnerability: added _validate_url() with scheme allowlist for all fetched URLs
• Added 30-second request timeouts to all requests calls (diff fetch + Discord webhook)
• Replaced bare except clauses with specific exception types (requests.RequestException, FileNotFoundError, ValueError, json.JSONDecodeError)
• Added input validation: file existence/size checks for audio, empty-diff handling
• Implemented actual LLM-based code analysis via GPT-4o (replaced stub analyze_code_changes)
• Added logging module throughout; removed silent error swallowing
• Lazy-initialized OpenAI client with clear error on missing key
• Improved error handling in voice note transcription (graceful skip on failure)
• Enhanced health check script compatibility with chroot/container environments
