Implementation Reference

  • src/index.ts:278-309 (registration)
    The tool 'get_subscription_info' is registered from line 280 to 308 using server.tool(). The registration includes a description, an empty schema (no params), and an inline async handler.
    // ── Tool: get_subscription_info ──────────────────────────────
    
    server.tool(
      "get_subscription_info",
      "Get subscription plans and free trial info.",
      {},
      async () => {
        const info = {
          website: "https://www.quanttogo.com",
          freeTrial: "30 days, all strategies, instant activation via register_trial",
          howToStart: {
            step1: "Call register_trial with your email → get API key instantly",
            step2: "Call get_signals with API key + productId → see buy/sell signals",
            step3: "Call check_subscription to check trial status",
          },
          plans: {
            free: "Browse strategies and compare performance",
            trial: "Full signal access for 30 days — all 8 strategies, US + China",
            subscriber: "Ongoing access + push notifications + position sizing",
          },
          upgrade: "admin@quanttogo.com",
        };
        return {
          content: [
            {
              type: "text" as const,
              text: JSON.stringify(info, null, 2),
            },
          ],
        };
      }
    );
  • The handler function for get_subscription_info. It returns static subscription plan info (free, trial, subscriber tiers) plus instructions on how to start.
    async () => {
      const info = {
        website: "https://www.quanttogo.com",
        freeTrial: "30 days, all strategies, instant activation via register_trial",
        howToStart: {
          step1: "Call register_trial with your email → get API key instantly",
          step2: "Call get_signals with API key + productId → see buy/sell signals",
          step3: "Call check_subscription to check trial status",
        },
        plans: {
          free: "Browse strategies and compare performance",
          trial: "Full signal access for 30 days — all 8 strategies, US + China",
          subscriber: "Ongoing access + push notifications + position sizing",
        },
        upgrade: "admin@quanttogo.com",
      };
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify(info, null, 2),
          },
        ],
      };
    }
  • The input schema for get_subscription_info is an empty object ({}), meaning it takes no input parameters.

Behavior2/5

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

The description is minimal and does not disclose behavioral traits such as authentication requirements, response structure, or whether it is read-only. With no annotations, the burden is entirely on the description, which falls short.

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 description is a single short sentence, which is concise but could be more informative without becoming verbose.

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 parameterless info retrieval tool, the description covers the basic purpose, but lacks details about return format or data scope. Given no output schema, more context would be beneficial.

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 input schema has zero parameters, so schema description coverage is 100%. The description does not need to explain parameters, but it could add context about what 'plans' and 'free trial info' include.

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 subscription plans and free trial info, using specific verbs and resources. However, it does not differentiate from the sibling check_subscription, which could overlap.

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 like check_subscription, nor any context on prerequisites or usage scope.

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