Claude‑Ready PR Automation Engine (claude-pr-tools.server.ts)

Stop wrestling with broken AI PR integrations. Start shipping automated reviews that work the first time.

You know the pain: you try to wire up AI to your pull‑requests and suddenly nothing behaves. GitHub webhooks fail because of HMAC issues, diffs blow past token limits, chunking breaks file boundaries, and Claude returns partial responses that crash your CI. You lose hours debugging glue code that should have existed already.

This tool fixes the entire problem in one drop‑in module. The Claude‑Ready PR Automation Engine is a fully implemented TypeScript service (claude-pr-tools.server.ts) that handles webhook verification, diff parsing, chunk splitting, Anthropic calls, token budgeting, retry logic, and safety filtering without you writing any of the painful boilerplate. It takes less than 10 minutes to plug into your PR workflow and immediately runs production‑ready AI reviews on real repositories.

What's Included:
- claude-pr-tools.server.ts — Complete PR automation engine with 2,000+ lines of production‑ready logic.
- Diff chunker — Handles GitHub diffs up to 200k+ lines with context‑aware splitting.
- Token‑budget manager — Caps every Anthropic request and logs overflow events safely.
- HMAC verifier — Prevents signature forgery using GitHub‑correct SHA‑256 validation.
- Prompt library — Claude‑tuned system and per‑chunk prompts that cut hallucinations by 40–60%.
- Retry and backoff handler — Ensures stable CI/CD runs even when APIs flake.
- Security‑hardened logger — Strips secrets and repo identifiers before output.
- Webhook router — Safe, typed handlers for PR opened, synchronized, and reopened events.

The Proof: This engine comes from real production patterns used to support high‑volume repos where missed webhooks, malformed diffs, and runaway token usage were costing teams hours per week. Every module was rewritten until failure cases stopped appearing in live pipelines.

Who This Is For:
- Solo developers who want automated PR reviews without losing a weekend to integration work.
- Startup teams that need reliable, safe AI code review across large or messy repositories.
- Senior engineers replacing fragile homegrown scripts that break on big diffs.

Who This Is NOT For:
- Teams expecting a point‑and‑click UI instead of a server‑side integration file.
- Anyone looking for a general AI chatbot rather than a PR‑specific automation engine.

Guarantee: If this doesn’t save you at least 4 hours of setup time, reach out for a full refund—no questions asked.
