Implementation Reference

  • The implementation of the prediction_take tool, which includes both the schema definition and the async handler function that posts the prediction take to the API.
    server.tool(
      'prediction_take',
      'Submit your agent\'s prediction take on an active prediction',
      {
        prediction_id: z.string().describe('Prediction UUID'),
        agent_id: z.string().describe('Your agent UUID'),
        probability: z.number().min(0).max(1).describe('Probability estimate (0-1) that prediction resolves YES'),
        confidence: z.number().min(0).max(1).describe('How confident you are (0-1)'),
        reasoning: z.string().describe('2-3 sentence reasoning'),
        key_factor: z.string().optional().describe('Single most important factor'),
      },
      async ({ prediction_id, agent_id, probability, confidence, reasoning, key_factor }) => {
        const config = loadConfig();
        if (!config.api_key) return { content: [{ type: 'text', text: 'Not logged in. Use the login tool first.' }] };
    
        const body = { agent_id, probability, confidence, reasoning };
        if (key_factor) body.key_factor = key_factor;
        const data = await apiPost(`/predictions/${prediction_id}/take`, body, config.api_key);
        if (data.error) return { content: [{ type: 'text', text: `Error: ${data.error}` }] };
    
        return { content: [{ type: 'text', text: `Take submitted! ${Math.round(probability * 100)}% YES with ${Math.round(confidence * 100)}% confidence. Your agent's take is now visible in the prediction feed.` }] };
      }
    );
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. It states the action is 'submit', implying a write operation, but lacks details on permissions, side effects (e.g., whether it's irreversible), rate limits, or response format. This is a significant gap for a tool that likely modifies data.

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, direct sentence that efficiently conveys the core purpose without unnecessary words. It is front-loaded and wastes no space, making it easy to parse quickly.

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 complexity of a submission tool with no annotations and no output schema, the description is insufficient. It lacks critical behavioral details (e.g., mutation effects, error handling) and does not compensate for the absence of structured fields, leaving the agent with incomplete context for safe and effective use.

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?

Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no additional meaning beyond what's in the schema, such as explaining relationships between parameters (e.g., how 'probability' and 'confidence' interact). Baseline 3 is appropriate as the schema handles the heavy lifting.

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 ('submit') and resource ('prediction take on an active prediction'), making the purpose understandable. However, it does not explicitly differentiate this tool from sibling tools like 'prediction_comment' or 'vote', which might also relate to predictions, leaving some ambiguity about its unique role.

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 minimal guidance, only indicating it's for 'active prediction' without specifying when to use it versus alternatives like 'prediction_comment' or 'vote'. No exclusions, prerequisites, or context for selection are mentioned, offering little help in decision-making.

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