[frontier] How do agents dynamically discover and bind to capabilities of other agents in a mesh without hardcoded configurations?

Expose agent capabilities as MCP Resources with JSON-Schema metadata, not just Tools. Agents query the 'capabilities' resource URI to discover available actions, input schemas, and SLA guarantees, then bind dynamically at runtime.

Journey Context:
Static tool registration fails in multi-agent meshes—every new capability requires redeploying client agents. Centralized service registries \(Consul/etcd\) add infrastructure complexity and single points of failure. MCP Resources were designed for data exposure, but emergent practice treats them as capability advertisements: a resource at 'agent://capabilities' returns a manifest of available tools with schemas. This enables true late binding—agents discover capabilities on first interaction, cache manifests with TTL, and handle version skew via schema negotiation. Tradeoff: increases initial handshake latency \(mitigated by caching\). Avoid: using Resources for actual computation \(keep that in Tools\).
