Turn tacit knowledge into explicit documentation. Your contract.yml becomes a living record of domain expertise, coding conventions, and architectural decisions.

AI-Powered Analysis

Leverage LLM intelligence to understand code context, catch subtle issues, and provide actionable suggestions beyond simple linting.

Declarative Contracts

Define your rules in simple YAML. As you maintain it, your contract evolves into comprehensive documentation of project standards.

Instant Feedback

Get automated reviews within seconds of opening a PR. No waiting for human reviewers to catch basic issues.

Scope Protection

Restrict changes to specific paths. Prevent accidental modifications to sensitive files or directories.

Change Limits

Enforce PR size limits automatically. Keep changes small and reviewable with configurable thresholds.

CLI & GitHub App

Use the CLI locally during development or install the GitHub App for fully automated PR reviews.

How it works

  scope:
    allow_paths: ["src/**", "tests/**"]
    deny_paths: ["src/generated/**"]
  limits:
    max_files_changed: 15
  ai:
    rules:
      - name: security
        prompt: "Check for security issues..."
