latest_executions_api

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

No annotations are provided, and the description only states 'retrieve latest executions' without any behavioral details such as mutability, rate limits, or whether it's read-only. This is insufficient for understanding side effects or constraints.

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 concise sentence in Japanese, effectively communicating the core purpose without verbosity. However, it lacks front-loaded structure or additional breakdown.

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?

Given there is an output schema (not detailed), the description need not explain return values. However, for a tool with only 2 parameters, the description is too sparse—it does not acknowledge that symbol is required or that count is optional, which a complete description should hint at.

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 2 parameters with 50% description coverage (symbol has a generic label, count has none). The description does not mention parameters or add semantic meaning beyond the schema, failing to clarify their purpose or constraints.

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 specifies the action (retrieve) and resource (latest execution list) for GMO Coin FX. It distinguishes from sibling tools, which are mostly order-related.

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 usage for retrieving recent executions, but does not explicitly state when to use this tool versus alternatives like active_orders_api or open_positions_api. No exclusions or prerequisites are provided.

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