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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the description's added value is minimal. It adds that the data is 'recent' and 'public', which is useful but brief. No mention of rate limits, pagination, or return format.

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 a single sentence, concise and easy to read. However, it could be more informative without increasing length significantly, such as mentioning the parameters or output type.

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?

For a tool with two undocumented parameters and no output schema, the description should provide more context about usage and return values. It only states the basic purpose, leaving significant gaps for an agent to understand correct invocation.

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 input schema has two parameters (market and account) with 0% description coverage. The description does not explain either parameter; it only vaguely mentions 'pair' which could refer to market. Users cannot understand what 'account' means in this context.

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 indicates the tool retrieves recent public trades for a trading pair, using the Portuguese word 'Negociações recentes' and 'Público'. It distinguishes from sibling tools like orderbook or ticker by focusing on trade history. However, it lacks an explicit verb like 'list' or 'get'.

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 provides no guidance on when to use this tool versus alternatives such as bity_executed_orders or bity_open_orders. It only mentions 'public', implying no authentication needed, but no explicit comparisons or context for selection.

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