Cayu Cayu is a production agent runtime for building and operating AI agents in Python. A harness turns a model into an agent by supplying its context, tools, permissions, and execution logic. Cayu gives applications control of the full agent execution lifecycle: how context is assembled, models and tools are invoked, where agent code runs, how state is persisted, authority is governed, failures are recovered, and behavior is observed and evaluated. Cayu provides durable agent-runtime primitives including sessions, task dispatch, leased workers, resumable workflow steps, approvals, and recovery. Applications can use them directly without a separate workflow engine. Applications retain control of their UI, authentication, domain logic, and business workflows. Cayu is designed for agents that do consequential or long-running work. You compose its runtime primitives directly in your application. Why we built Cayu Cayu was extracted from the production runtime behind an agent-operated software factory that built and deployed thousands of business applications.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
