Core Concepts

The agent kernel in rho-core is built on a small set of interlocking concepts.

• Agent Loop — the state machine that drives the conversation, returning AgentResult with structured output
• Tool Trait — the interface all tools implement
• Provider Architecture — provider-agnostic model access
• Approval Policy — the gate between tool calls and execution
• Context Management — keeping the conversation within the context window
• Sessions — persistent, tree-structured conversation state
• Project Context Files — loading and trusting project-level instructions
