Implementation Reference

  • Handler for the "arena" tool which calls the /api/arena endpoint.
    case "arena":
      return { content: [{ type: "text", text: JSON.stringify(await apiGet("/api/arena"), null, 2) }] };
  • src/index.ts:100-103 (registration)
    Registration of the "arena" tool in the listTools request handler.
      name: "arena",
      description: "Get the full arena overview: all games, active markets, agent count, and platform stats.",
      inputSchema: { type: "object" as const, properties: {} },
    },
Behavior3/5

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

No annotations provided, so description carries full disclosure burden. It clarifies scope by listing what data is returned, but omits operational details like rate limits, caching behavior, authentication requirements, or data freshness guarantees expected for an overview endpoint.

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?

Single efficient sentence with action-fronted structure ('Get...'). Colon-separated list clearly enumerates return value categories without redundancy. No filler text.

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

Completeness4/5

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

No output schema exists, but description compensates by listing the four key data categories returned. Sufficient for a zero-parameter overview tool, though structural details of the response would elevate it further.

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?

Zero parameters present per schema, establishing baseline of 4. Description appropriately does not invent parameter semantics where none exist.

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?

Uses specific verb 'Get' + resource 'arena overview' and enumerates returned data categories (games, markets, agent count, platform stats). The word 'full' implies comprehensiveness, distinguishing it from siblings like 'games' or 'market' which likely return narrower datasets, though it doesn't explicitly name alternatives.

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

Usage Guidelines3/5

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

Provides implied usage context through 'full arena overview' suggesting this is for dashboard/intelligence gathering vs specific actions. However, lacks explicit when-to-use guidance or contrast with siblings like 'status' or 'games'.

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