RealityGate scores AI-generated code and blocks stubs, fake data, invented packages, and leaked secr

RealityGate is an open-source CLI, Claude Code plugin, and GitHub Action for checking AI-generated code in JavaScript, TypeScript, Python, and Go. It assigns a Reality Score from 0 to 100 and reports issues with file and line references plus a fix plan. It includes 22 built-in rules for common AI coding failures, along with `selftest` to verify that rules can catch violations and `scan-skills` to check skills and plugins for security red flags. It runs locally, has no runtime dependencies, sends no telemetry, and does not read `.env` file contents.

Pick a stack. Brix installs the skills. Your prompt and your agent build the repo.

Brix is a command-line tool for setting up a project stack for a coding agent. You choose the frontend, API, database, and agent; Brix checks that the choices fit and installs the skills into an empty folder. It writes files including stack.json, agent instructions, a prompt starter, and skills for Cursor, Codex, or Claude Code. The stack can include core technologies, services, cloud setup, and tools.

Keploy builds a Digital Twin of your production behavior — real API traffic, mocks, and dependencies

Keploy turns real application traffic into tests and dependency sandboxes, then replays them to verify changes locally, in CI, or across Kubernetes. It captures requests and dependency calls without code changes and converts them into editable tests and mocks. The platform is for developers and coding agents verifying application changes, including AI-generated code. It can generate API tests from traffic, specifications, and application context, and supports integration and regression testing with virtualized dependencies.
