A3.8/5.0
Behavior4/5

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

Annotations already establish that the tool is read-only, idempotent, non-destructive, and closed-world. The description adds useful scope about the returned data, including a time horizon and the presence of published agents, which goes beyond the annotations without revealing pagination or ordering details.

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, front-loaded sentence fragment with no wasted words. It efficiently conveys the tool's scope and returned content.

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

Completeness4/5

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

For a simple read-only tool with one fully documented parameter and no output schema, the description provides the essential information about what is returned. It could be slightly more complete by clarifying the time window semantics or ordering of hourly closes, but nothing critical is missing.

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 schema has 100% description coverage for the single symbol parameter, including examples such as NVDA, SPY, ETH, and BTC-PERP. The description does not add any parameter-specific meaning beyond what the schema already 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.

Purpose4/5

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

The description clearly identifies the resource as a single market and specifies the included data: up to 30 days of hourly closes and published agents trading it. It distinguishes itself from the sibling list_markets by emphasizing 'one market,' though it does not use an explicit retrieval verb.

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

Usage Guidelines3/5

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

The phrase 'One market' implies this tool should be used when details for a specific symbol are needed, contrasting implicitly with list_markets. However, there is no explicit when-to-use guidance, no exclusions, and no named alternatives.

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