Implementation Reference

  • Tool handler for "game_end" which extracts public_id and calls rails.endGame.
    async (input) => {
      const publicId = requireString(
        (input as { public_id?: unknown })?.public_id,
        "public_id"
      );
      return rails.endGame(publicId);
    }
  • Registration of the "game_end" tool with description and input schema.
    addTool(
      {
        name: "game_end",
        description: "End a game.",
        inputSchema: {
          type: "object",
          properties: {
            public_id: { type: "string" },
          },
          required: ["public_id"],
        },
      },
  • Actual implementation of endGame logic, executing the HTTP request to the Rails API.
    async endGame(publicId: string): Promise<GameState> {
      return this.requestJson<GameState>(
        "POST",
        `/games/${encodeURIComponent(publicId)}/end`,
        undefined,
        true
      );
    }
Behavior2/5

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

With no annotations provided, the description carries full burden but discloses no behavioral traits. It does not clarify if ending is destructive (deletes data), reversible, idempotent, or what happens to game state post-invocation.

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

Conciseness3/5

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

The three-word description is efficiently structured with no redundancy, but extreme brevity results in under-specification rather than effective conciseness—it wastes no words while failing to communicate necessary information.

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?

Incomplete for a lifecycle management tool: no output schema exists (so return values should be described), the single parameter lacks documentation in both schema and description, and behavioral side effects are omitted despite zero annotation coverage.

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

Parameters1/5

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

Schema coverage is 0% and the description completely fails to mention the 'public_id' parameter or explain what identifier is required (game ID? user ID?), leaving the agent without semantic guidance for the single required input.

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

Purpose2/5

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

The description 'End a game.' restates the tool name 'game_end' with minimal expansion (tautology). While it identifies the resource (game), it fails to distinguish from siblings like game_open or clarify what 'ending' entails (termination vs. archival vs. deletion).

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 provided on when to invoke this tool versus alternatives (e.g., when to use game_end vs. game_open), nor any prerequisites (e.g., game must be active) or post-conditions mentioned.

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