Episode notes
Agency Is A Spectrum
- Agency exists on a spectrum from single LLM calls to multi-agent networks orchestrating many tasks.
- Higher agency includes code execution, tool calls, memory, and multi-step orchestration rather than a single prompt loop.
Compose Agents And Workflows
- Mastra's primitives are composable: agents can call workflows and workflows can include agents and tools as steps.
- This composition lets engineers shape determinism and handoffs across agentic components.
Use Workflows As Guardrails
- Use workflows to add determinism and observability when models are unreliable for complex multi-step tasks.
- Instrument each step with tracing and a dev playground to debug non-deterministic LLM behavior.
