What it solves

Coding agents often ship code that contains bugs because they lack a reliable way to verify their work in a real environment. This project provides a verification layer that allows coding agents to test their output against a live application, identify failures, and receive a self-consistent error bundle to fix the issues before the code is finalized.

How it works

The CLI integrates directly into your coding agent's workflow. It allows the agent to create, run, and triage tests using plain-language plans. When a test fails, the CLI generates a failure bundle that the agent can read to understand exactly what broke. For local development, it includes a tunneling feature that allows the platform to access your local application (e.g., localhost) to perform these tests without needing to deploy to a staging environment first.

Who it’s for

This tool is designed for developers who use AI coding agents (such as Claude, Cursor, Cline, or Windsurf) and want to automate the verification of the code those agents produce.

Highlights

• Agent-First Integration: Automatically installs verification skills for popular coding agents like Claude, Cursor, and Cline.
• Self-Healing Loop: Enables agents to run tests, read failure reports, and automatically iterate on their own code until it passes.
• Local Tunneling: Securely exposes local development servers to the testing platform for real-time verification.
• Plain-Language Plans: Uses simple JSON-based test plans that describe user actions and assertions, avoiding the need for complex browser automation code.
