Astrai Code Review
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_KEYwithout provider keys, Astrai uses its own hosted models. Still routed intelligently, still cheap.
Setup
- Get a free API key at as-trai.com
- Set
ASTRAI_API_KEYin your environment or skill config - Optionally add provider API keys for BYOK routing (e.g.
ANTHROPIC_API_KEY,OPENAI_API_KEY) - Run
/reviewon any diff or PR
Usage
/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:
/review
Returns issues found in the current diff with severity levels and suggestions.
Strict review for a PR:
/review --strict
Catches not just bugs but also style violations, naming issues, and missed best practices.
Security audit:
/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.
