Agent
Implements one well-defined task from an approved plan or spec. Needs a self-contained task description; not for exploratory or ambiguous work. Pinned to sonnet - dispatch with model=opus for multi-file, architectural, or subtle work.
Agent
Read-only codebase explorer. Use for "where is X", "how does Y work", "which files touch Z" - returns conclusions with file:line refs, never file dumps. Never modifies anything.
Agent
Read-only breadth sweeps over a codebase - enumerate, list, trace a chain end to end ("list every stage in order", "which files import X", "where does this pipeline end"). Returns the list or the ordering, never file dumps. Use scout instead when the answer needs judgement about what code does. Never modifies anything.
