Noizu.MCP.Server.Tool.Spec (Noizu MCP v0.1.6)

Normalized runtime descriptor for one registered tool.

Every tool module — classic use Noizu.MCP.Server.Tool modules and use Noizu.MCP.Server.Toolkit multi-tool modules alike — exports __mcp_tools__/0 returning a list of these. The server runtime (Noizu.MCP.Server.Features.Tools.expand/1) works exclusively on specs: the definition is what tools/list advertises, module/fun/arity are how tools/call invokes the handler, and cast_plan/output_schema drive argument casting and structured-output checking.

evals holds compiled Noizu.MCP.Eval.Spec structs (spec §4) — description-tuning eval definitions attached via the tool DSL. They are compile-time metadata for the mix noizu.mcp.eval harness and are never serialized onto the wire: only definition reaches tools/list / the catalog.
