Tool Use And Agents

Long-form references on tool use, agent environments, and reliability loops.

Agent Environments

  • Harness Engineering
    Useful framing around agents as systems shaped by environments, specs, feedback, and reliability loops.

  • Code Mode
    A concrete argument for exposing tools through code interfaces rather than forcing every step through chat-level tool calls.

  • Context Mode
    A useful pattern for keeping agent context manageable when tools produce large or noisy outputs.
