Each tool has a clearly distinct purpose: delegate runs one sub-agent, delegate_batch runs many, list_agents shows available agents, and validate_agents checks agent files. There is no meaningful overlap; even delegate and delegate_batch are distinguishable by scope.

All tool names follow a consistent verb_noun pattern in snake_case: delegate, delegate_batch, list_agents, validate_agents. The pattern is uniform and predictable, making the set easy to navigate.

Four tools is well-scoped for managing and running sub-agents. Each tool addresses a distinct part of the workflow (single run, batch run, discovery, validation), leaving no unnecessary bulk or sparseness.

The core delegation lifecycle is covered: listing available agents, validating configuration, running individually, and running in batches. Minor gaps exist such as no explicit tool to fetch agent details or stop/abort runs, but these do not block the primary use case.
