ost AI agent libraries are markdown files in a folder. Operator Agents is different. Every agent ships with a structured YAML schema defining: • tools.required — what the agent needs to run • context.required — what inputs you must provide • output.format — json, markdown, code, or mixed • pipeline.handoff_to — which agent runs next + condition This makes agents composable. An orchestrator can read agent-index.json and route tasks automatically.
