Astrai Code Review

AI-powered code review with intelligent model routing — saves 40%+ vs always using the most expensive model

AI-powered code review with intelligent model routing. Complex logic goes to powerful models. Formatting and style goes to fast, cheap ones. You save 40%+ without sacrificing quality.

What it does

• Smart routing for reviews: Astrai analyzes the diff complexity and routes to the optimal model. A gnarly concurrency bug gets Opus. A missing semicolon gets Haiku. You only pay for the intelligence you need.
• Structured output: Every review returns typed issues with file, line number, severity (critical/warning/info), message, and a concrete suggestion.
• Strictness modes: Standard catches bugs and logic errors. Strict adds style and best-practice checks. Security mode focuses on vulnerabilities, injection, auth, and data exposure.
• BYOK (Bring Your Own Keys): Your provider API keys stay with you. Astrai decides which model to use, then calls the provider using YOUR key. You pay providers directly.
• Cost tracking: Every review response includes the cost and how much you saved vs always using the most expensive model.
• Local-only mode: If you only set ASTRAI_API_KEY without provider keys, Astrai uses its own hosted models. Still routed intelligently, still cheap.

Setup

1. Get a free API key at as-trai.com
2. Set ASTRAI_API_KEY in your environment or skill config
3. Optionally add provider API keys for BYOK routing (e.g. ANTHROPIC_API_KEY, OPENAI_API_KEY)
4. Run /review on any diff or PR

Usage

text

/review                     Review the current diff (staged changes)
/review --strict            Strict mode: bugs + style + best practices
/review --focus security    Security-focused review (vulns, injection, auth)
/review --file src/auth.py  Review a specific file

Examples

Basic review of staged changes:

text

/review

Returns issues found in the current diff with severity levels and suggestions.

Strict review for a PR:

text

/review --strict

Catches not just bugs but also style violations, naming issues, and missed best practices.

Security audit:

text

/review --focus security

Focuses on SQL injection, XSS, auth bypass, hardcoded secrets, insecure deserialization, and other vulnerability classes.

Security & Privacy

• All requests authenticated via API key in the Authorization header
• Diffs are sent to the Astrai routing API, which forwards to the selected provider
• In BYOK mode, provider keys are sent via encrypted header (X-Astrai-Provider-Keys) and never stored
• No diffs, code, or review results are retained by Astrai after the request completes
• Source code is fully open: github.com/beee003/astrai-openclaw

Model Invocation

This skill sends code diffs to the Astrai routing API. The router classifies the review complexity and selects the best model:

• High complexity (concurrency, security, architecture): Routes to Claude Opus, GPT-4o, or Gemini Pro
• Medium complexity (logic errors, missing edge cases): Routes to Claude Sonnet, GPT-4o-mini, or Gemini Flash
• Low complexity (formatting, typos, naming): Routes to Claude Haiku, GPT-4o-mini, or Gemini Flash

Your prompts are processed by third-party LLM providers according to the routing decision. In BYOK mode, calls are made using your own provider API keys.

Pricing

Same as Astrai platform pricing:

• Free: 1,000 requests/day, smart routing, all strictness modes
• Pro ($49/mo): Unlimited requests, priority routing, analytics dashboard
• Business ($199/mo): Team dashboards, compliance exports, SLA guarantee
