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

No annotations provided, so description carries full burden. It adds that the response includes 'current market info,' indicating the data payload type. However, it omits rate limits, caching behavior, authentication requirements, or specific return structure (JSON array vs object) that would help an agent handle the response.

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?

Single sentence, front-loaded with action verb. No filler words. The parenthetical examples efficiently communicate scope without requiring additional sentences. Every clause earns its place.

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?

Appropriate for a simple parameterless tool. Mentions return content ('current market info') which partially compensates for missing output schema. Could improve by indicating return format (array of game objects), but sufficient for basic agent invocation decisions given the low complexity.

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?

Zero parameters with 100% schema description coverage (trivially). Per rubric, baseline score of 4 applies as there are no parameters requiring semantic elaboration beyond the schema.

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?

Excellent specificity: verb 'List' + resource 'prediction games' + concrete examples (BTC, ETH, SOL, SPY). The inclusion of 'current market info' distinguishes it from the sibling 'market' tool (likely specific analytics) and 'bet' (action-oriented), clarifying this is an enumeration/discovery function.

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?

Usage is implied (discover available assets before trading/betting), but lacks explicit workflow guidance such as 'use this before placing bets with the bet tool' or differentiation from the 'market' sibling. No when-not-to-use guidance provided.

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