Implementation Reference

  • Handler function for the fsp_build_info tool - returns a placeholder 'Build info' string
    export const buildInfoHandler = async () => { return { content: [{ type: "text", text: "Build info" }] }; };
  • Schema registration for fsp_build_info tool - defines name, description and input schema (no properties)
    {
      name: "fsp_build_info",
      description: "Get FSP build-related information",
      inputSchema: {
        type: "object",
        properties: {}
      }
    },
  • src/index.ts:165-166 (registration)
    Dispatch for the fsp_build_info tool - routes call to buildInfoHandler()
    case "fsp_build_info":
      return await buildInfoHandler();
  • src/index.ts:16-16 (registration)
    Import of the buildInfoHandler from the handlers/build module
    import { buildInfoHandler } from "./handlers/build.js";
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It only states that the tool 'gets' information, implying it is read-only, but provides no details on safety, idempotency, or potential side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence that is efficiently concise. It could be slightly more informative without sacrificing brevity, but it avoids verbosity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema, the description should elaborate on what the tool returns (e.g., build version, date, dependencies). Without this, the agent has insufficient context to judge the tool's utility.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, and the schema coverage is trivially 100%. The description adds no parameter information, but none is needed. Baseline for zero parameters is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves build-related information, distinguishing it from sibling tools like fsp_info or fsp_version. However, it lacks specificity about what exactly constitutes 'build-related information'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The description does not mention scenarios or prerequisites, leaving the agent to infer context from the tool name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
