ai_agent_stats

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

The description includes pricing ($0.06/call) and free tier usage (50/50 today), which provides some behavioral context about cost and limits. However, no annotations exist, and the description does not indicate if the tool is read-only or has side effects.

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

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

The description is concise but unstructured, mixing pricing, API endpoint, and free tier in a single line. It could be better formatted for clarity.

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

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

Given zero parameters and no output schema, the description provides basic context (market, cost, API). However, it does not describe the output or the nature of the statistics, leaving some gaps.

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

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

The tool has zero parameters, so the description cannot add meaning beyond the input schema. Baseline score of 4 applies as per guidelines.

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

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

The description states 'AI Agent Statistics' with a '[Market]' prefix, suggesting market-related stats, but does not specify what statistics are provided (e.g., usage, performance, count). The purpose is vaguely implied but not clearly defined.

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

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

No guidance on when to use this tool vs. alternatives among the many sibling tools. No mention of typical use cases or scenarios.

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