# How Read [the workflow contract](../../references/workflow-contract.md). Build a senior engineer's working mental model, not annotated source. 1. State the question and boundaries. For a known symbol or narrow module, trace it directly; do not delegate a trivial lookup. 2. For a broad unfamiliar subsystem, identify independent slices worth exploring. Batch `agent` calls to the available `explorer` with self-contained questions built from `references/explorer-prompt.md`. No model-per-call selection. If that ID is unavailable, inspect `rho` action `agents`, or investigate directly. 3. Await all required findings. Follow real entry points, types, ownership, state, calls and errors; cite file/line evidence and resolve contradictions in source. 4. Synthesize using `references/explainer-prompt.md`; usually do this in the parent, not another delegate just to rephrase. Keep unknowns visible. Return only applicable sections: Overview, Key concepts, How it works, Where things live, Gotchas. A small Mermaid diagram helps when control flow or relationships are the point. Distinguish mechanism from rationale; use `why` for motivation.
