Agent Tdd London Swarm

A London School TDD agent that lives in the mockist camp and coordinates with other testing agents in a swarm setup. It drives outside-in development using mocks to define contracts between objects, focusing on interaction testing rather than state verification. You'd reach for this when you want behavior-driven design where mocks shape your interfaces, especially in multi-agent workflows where different test agents handle unit, integration, and contract verification in parallel. The swarm coordination is interesting but adds complexity, so it's really only worth it if you're already running multiple specialized test agents that need to share mock contracts and aggregate results.
