Implementation Reference

  • The main handler function for the 'geocode_address' tool. It validates the input address and delegates to the GoogleMapsClient's geocode method.
    async geocode_address(args: Record<string, unknown>) {
      if (!cfg.googleApiKey) throw new Error("GOOGLE_API_KEY is not configured");
      const address = String(args.address || "");
      if (!address) throw new Error("address is required");
      return client.geocode(address);
    },
  • Input schema definition for the 'geocode_address' tool, specifying the required 'address' string parameter.
    inputSchema: {
      type: "object",
      properties: {
        address: { type: "string" },
      },
      required: ["address"],
    },
  • Tool registration object for 'geocode_address' within the Google Maps tools array, including name, description, and schema.
    {
      name: "geocode_address",
      description: "Geocode a human-readable address",
      inputSchema: {
        type: "object",
        properties: {
          address: { type: "string" },
        },
        required: ["address"],
      },
    },
  • Helper method in GoogleMapsClient class that performs the actual geocoding API request to Google Maps.
    geocode(address: string) {
      return this.request("/maps/api/geocode/json", {
        query: { address, key: this.apiKey },
      });
    }
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure but only states the basic action. It doesn't reveal if this is a read-only operation, potential rate limits, accuracy considerations, or what the output might look like (e.g., coordinates), which is inadequate for a tool with zero annotation coverage.

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 extremely concise with a single, direct sentence that front-loads the core purpose without any wasted words. Every part of the sentence earns its place by clearly stating the tool's function.

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 annotations and output schema, the description is incomplete. It doesn't explain what geocoding entails (e.g., converting to coordinates), potential errors, or return values, leaving significant gaps for the agent to understand the tool's full behavior and output.

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

Parameters3/5

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

The schema description coverage is 0%, so the description must compensate, but it only vaguely implies the 'address' parameter without detailing format, examples, or constraints. This adds minimal value beyond the schema's basic type definition, resulting in a baseline score due to the single parameter.

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 action ('geocode') and the resource ('a human-readable address'), making the purpose immediately understandable. It doesn't differentiate from siblings since no other geocoding tools exist in the sibling list, but it's specific enough to stand alone.

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. It doesn't mention prerequisites, limitations, or related tools like 'search_places' that might offer overlapping functionality, leaving the agent to infer usage context.

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