Field notes on AI-era growth, deliverability, voice, and messaging for developers and teams building on Orbit by Devotel.
Agent-to-agent (A2A) is the open protocol for letting one AI agent delegate a task to another, with discovery via a public Agent Card and a task lifecycle over JSON-RPC. This explainer decodes what A2A actually specifies, how it complements the Model Context Protocol (MCP), and how Devotel Orbit's multi-agent squads sit on top of it.
The four orchestration patterns a Devotel Orbit buyer actually chooses between — one canonical agent, a classifier-and-specialists squad, a champion-challenger rollout, and role-play rehearsal — indexed against the shipped /agents surfaces, with a decision rule and a worked scenario for each.
How Devotel Orbit's agent squads compose a classifier and specialist agents behind one conversation, why specialization beats a single monolithic prompt, and what routing, memory, model presets, and squads each own.
