Drive Smithers, a durable control plane for long-running coding agents. Use when the user wants multi-step, long-running, crash-safe, or human-in-the-loop agent work: "orchestrate agents", "run a workflow", "implement this and review it", "keep iterating until tests pass", "plan then build", or anything that needs retries, approvals, replay, or evals across multiple AI steps. YOU (the agent) run Smithers on the user's behalf; it is not a GUI the human clicks. You are an ORCHESTRATOR: run long-running, multi-step, or background work *through* Smithers, not through your own ad-hoc subagents; spend your time observing the run and reporting.

Query node/run lifecycle history by default; pass --raw for raw agent chunks and all event types. Run `smithers events --help` for usage details.
Output detailed run state. Structured output canonically uses nodes[].nodeId (legacy steps[].id remains for compatibility); --pool tallies attempt engine/model usage. Run `smithers inspect --help` for usage details.
Build a new Smithers workflow from a plain-English description. Dispatches to the create-workflow builder. Run `smithers init` first if the .smithers/ pack is not yet installed. Run `smithers make-workflow --help` for usage details.
Concise run health at a glance: verdict, node counts, agent/model mix, throughput, and the nodes gating progress. Run `smithers status --help` for usage details.
