ai-pr-bot: Instructions file for Claude Code

CLAUDE.md

ai-pr-bot CLAUDE.md is an instructions file for Claude Code from sgharlow/ai-pr-bot. It costs 518 tokens per session, scanned A, original, MIT.

Repository-specific instructions for an AI GitHub pull-request review bot. A pull request is a proposed code change on GitHub that others can review before it is merged.

In plain words
What is it for?
Installing dependencies, running development or production commands, generating and applying database migrations, and working on the API, GitHub integration, AI review service, and job queue.
Why use it?
It gives the coding agent the project's commands, architecture, and database steps so changes fit the existing TypeScript, Fastify, Prisma, Redis, and GitHub setup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ai-pr-bot CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture Overview

This is an AI-powered GitHub PR review bot built with TypeScript, Fastify, and Prisma. The application follows a modular architecture:

Core Components

  1. API Server (src/index.ts, src/app.ts)

    • Fastify-based REST API
    • Handles GitHub webhooks at /webhook/github
    • Health checks at /health

  2. GitHub Integration (src/lib/github/)

    • client.ts: GitHub App authentication and API client
    • diff-analyzer.ts: Analyzes PR diffs for review
    • Uses Octokit for GitHub API interactions

  3. AI Service (src/lib/ai-service/)

    • enhanced-ai-service.ts: OpenAI GPT-4 integration for code analysis
    • Performs security, performance, and quality reviews

  4. Queue System (src/lib/queue-system/)

    • Redis-based job queue using Bull
    • Async processing of PR review requests
    • Worker processes in src/worker.ts

  5. Database (PostgreSQL via Prisma)

    • Schema defined in prisma/schema.prisma
    • Stores repositories, reviews, and webhook events

Key Environment Variables

  • GITHUB_APP_ID: GitHub App ID for authentication
  • GITHUB_PRIVATE_KEY: PEM-formatted private key
  • GITHUB_WEBHOOK_SECRET: Webhook validation secret
  • OPENAI_API_KEY: OpenAI API key for GPT-4
  • DATABASE_URL: PostgreSQL connection string
  • REDIS_URL: Redis connection for job queue

Development Flow

  1. GitHub sends webhook events to /webhook/github
  2. Events are validated and queued in Redis
  3. Worker processes pick up jobs and analyze PRs
  4. AI service reviews code for issues
  5. Results are posted back as PR comments

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
