Where it applies

Jobs this tool actually does, and the surface each one is exercised on.

Produce a typed client for an API the agent is about to integrate against.
coding-agent

Writes a whole tree of files — an agent should generate into a scratch directory and diff, never straight over a working source tree.

Scaffold a server implementation from an agreed contract, so design-first actually happens.
coding-agentci-pipeline
Regenerate clients when a provider publishes a new version of its description.
