[frontier] How do agents dynamically discover and negotiate capabilities without hardcoded tool definitions?

Implement MCP capability negotiation: agents query ListTools on peer MCP servers at runtime, compare schemas, and dynamically construct ad-hoc workflows by matching output schemas of one tool to input schemas of another, caching the capability graph for the session.

Journey Context:
Static tool registration fails when agents need to collaborate across organizational boundaries where tool sets evolve. Early multi-agent systems hardcoded tool mappings, leading to version fragility. The alternative of universal JSON-schema negotiation is heavy; instead, lightweight MCP ListTools with schema hashing allows agents to treat capabilities as a discovery layer. This is winning because it decouples agent logic from tool implementations, enabling 'capability markets' where agents subscribe to evolving services without code changes.
