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

Annotations already cover the safety profile (read-only, idempotent, non-destructive), so the description does not need to repeat that. The description adds 'public' and 'recent' as behavioral context but does not disclose details like result limits, pagination, or time-window boundaries.

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, front-loaded sentence with no filler. Every word contributes to identifying the operation and scope.

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 simple one-parameter, read-only tool with annotations covering safety and an output schema present, the description is nearly sufficient. The only minor gap is that 'recent' is not quantified, but this is unlikely to prevent 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 schema already describes the only parameter thoroughly, including an example ('GRAM-USDT'), so schema coverage is complete. The description adds no additional parameter-level meaning beyond restating that it operates on one symbol.

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 identifies the operation ('Get recent public trades') and the scope ('for one symbol'), which is specific and actionable. It does not explicitly distinguish itself from sibling market-data tools, but the resource 'public trades' is unambiguous versus candles, orderbook, or tickers.

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 implies the tool is for retrieving recent public trade data for a single symbol, which gives reasonable context for when to use it. However, it does not mention alternatives or explicitly state when not to use it, leaving sibling differentiation to the tool names.

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