Sphynx

Sphynx runs coding agent evals. A suite holds cases, each case runs on variants (a harness, model and sandbox), and a batch starts those runs together so variants can be compared. Every run records its trials, command trajectories and pass rate.

Repository

This is a Bun and Turbo TypeScript monorepo containing:

• the TanStack Start dashboard
• the Effect HTTP API
• the sphynx-sh TypeScript SDK and CLI
• the hosted MCP server
• the eval runtime and sandbox adapters
• Product documentation

Setup

bun install
cp .env.example .env
bun run db:migrate
bun dev

The dashboard runs at http://localhost:3005, the API at http://127.0.0.1:3003, and the docs preview at http://localhost:3007.

See .env.example for database, authentication, harness, model, and sandbox credentials.

Commands

bun run docs
bun run openapi
bun run check
bun run typecheck
bun run test
bun run knip
bun run doctor

The pre-commit hook runs the repository checks.
