hip4_outcome_recent_trades

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

With no annotations provided, the description carries the full burden. It discloses exclusions (settlement, pair-redeem, auction-phase fills) and lists returned fields, but does not state whether the operation is read-only, has auth requirements, or any side effects. This is a moderate effort but incomplete.

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?

Two sentences efficiently deliver the purpose, exclusions, and return fields with no waste. The key information is front-loaded and easy to parse.

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?

The description is fairly complete for a tool without annotations or output schema: it states exclusions and lists return fields. It lacks information about authentication, rate limits, and output structure details (e.g., array vs. object), but covers the core functionality well.

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?

Schema coverage is 100%, and parameters are well-described in the schema with defaults and constraints. The description adds no additional meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

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 clearly states 'Get recent real fills for one HIP-4 outcome', providing a specific verb and resource. It excludes settlement, pair-redeem, and auction-phase fills, which distinguishes it from sibling tools like hip4_recent_settlements or hip4_outcome_summary that might include those.

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?

The description does not provide explicit guidance on when to use this tool versus alternatives. It only implies its purpose by listing exclusions, but fails to mention when not to use it or suggest superior alternatives.

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