Implementation Reference

  • The versionInfoHandler function that implements the 'fsp_version' tool logic. Returns FSP version information (v6.4.0) and release notes as text content.
    export const versionInfoHandler = async () => {
      return {
        content: [
          { 
            type: "text",
            text: `

  • The tool registration schema for 'fsp_version' including its name, description, and empty inputSchema (no parameters required).
    name: "fsp_version",
    description: "Get FSP version information and release notes",
    inputSchema: {
      type: "object",
      properties: {}
    }

    The CallToolRequestSchema case statement that routes 'fsp_version' to versionInfoHandler.
    case "fsp_version":
      return await versionInfoHandler();
Behavior2/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states the tool returns version info and release notes, but does not mention whether it is purely read-only, requires authentication, or the format of output. This is insufficient for a tool with zero annotation support.

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

Conciseness5/5

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

The description is a single, concise sentence that directly states the tool's purpose. Every word is earned with no redundancy or fluff.

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

Completeness3/5

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

For a simple tool with no parameters and no output schema, the description is somewhat complete. However, given the presence of sibling tools (fsp_build_info, fsp_info), the description does not clarify the exact scope of information returned, risking overlap confusion.

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 no parameters, and the input schema is empty with 100% description coverage. The description adds no parameter information, but none is needed. A baseline of 4 is appropriate as there are no parameters to explain.

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 FSP version information and release notes. It uses a specific verb ('Get') and resource. However, it does not differentiate from sibling tools like fsp_info or fsp_build_info, which might have overlapping purposes.

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?

The description provides no guidance on when to use this tool versus alternatives. Given several sibling tools (e.g., fsp_info, fsp_build_info), explicit usage context is needed but missing.

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