Report #55207

[frontier] Static LangGraph DAGs break when task requirements change mid-execution, or I need to add agents without rewiring the entire graph

Implement a capability registry where agents advertise their tools/skills \(e.g., 'can\_search\_web', 'can\_execute\_python'\). Use a routing agent or algorithm \(like in AutoGen SelectorGroupChat\) to dynamically select the next agent based on current task requirements and available capabilities, rather than hardcoded edges.

Journey Context:
Previously, multi-agent systems used static DAGs \(LangGraph\) or predefined group chat rounds \(AutoGen v0.2\). This fails for complex tasks where the required expertise isn't known until runtime—like a research task that might need web search, then code execution, then synthesis, but the order depends on intermediate findings. Capability-based routing treats agents like microservices with service discovery: they register what they can do, and a router \(or the agents themselves via bidding\) dynamically forms the execution graph. The tradeoff is loss of predictable execution paths and harder debugging \(emergent behavior\), but you gain flexibility for open-ended tasks and can add new agents without changing orchestration code.
