Layer 04 · CPL Agents
The agent code layer.
CPL Agents are the actual agent implementations — code, prompts, tool bindings, and AI BOM. They’re published as signed packages from Studio, certified against the Anchor standard, and load at runtime into Agent Core or a customer-deployed Meridian instance.
Multi-framework: an agent can be authored in ADK Go, LangChain, Anthropic SDK, or Microsoft Agent Framework. Same publishing pipeline, same passport, same evidence. The framework is an implementation detail; the contract with the platform is not.
- signed packages
- AI BOM included
- framework-agnostic
- reproducible builds
- reversible deploy
