[frontier] How do agents dynamically discover peer capabilities beyond static tool definitions in production?

Treat MCP servers as capability registries where agents expose JSON-LD semantic descriptions of skills \(not just tools\) to a shared MCP registry; implement discovery queries during the planning phase to dynamically bind agent capabilities at runtime rather than hardcoding tool schemas in prompts.

Journey Context:
Static tool definitions in prompts create tight coupling and prevent emergent agent composition. Frontier systems now use MCP as a dynamic service mesh: agents register their capabilities \(including sub-agents as tools\) with semantic metadata to MCP registries. During task planning, agents query the registry to discover relevant capabilities, enabling runtime composition of multi-agent workflows without code changes. Tradeoff: adds 50-100ms discovery latency, mitigated by client-side capability caching. Wrong approach: maintaining static YAML tool lists that require redeployment to update.
