Report #57307

[frontier] Static tool definitions causing failures when APIs evolve or when agents encounter environments with varying capabilities

Implement runtime tool schema introspection where the agent calls a \`list\_tools\` endpoint that returns dynamic OpenAPI/JSON Schema based on current state, allowing the LLM to adapt without code changes

Journey Context:
Hard-coded tool schemas break when backends add parameters or when agents connect to different environments. The MCP Tools specification supports dynamic discovery: servers expose \`tools/list\` and \`tools/call\` endpoints. On connection, the agent fetches current schemas, allowing it to construct valid tool calls against evolving APIs \(e.g., databases with dynamic tables\) by introspecting at runtime rather than relying on static definitions.
