cancel_option_order_by_id

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

The description only states the basic action without any behavioral details such as required order status, idempotency, or side effects. Since no annotations are provided, the description carries the full burden but fails to disclose important aspects.

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 very concise with no wasted words. However, the parameter section is somewhat redundant with the schema. Overall, it is appropriately sized for the simple functionality.

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 incomplete for a mutation tool. It lacks prerequisites, error conditions, return value expectations, and differentiation from siblings. Given the output schema exists, more detail on behavior and context is needed for safe 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 parameter description adds minimal meaning beyond the schema by naming the argument as 'order_id' and describing it as 'The ID of the order to cancel'. However, it lacks specifics on format, source, or constraints, and schema coverage is 0%.

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 it cancels a specific option order, providing a clear verb+resource. However, it does not differentiate from sibling tools like cancel_all_option_orders_tool or cancel_stock_order_by_id, which reduces clarity for selection.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention that it cancels a single order by ID or that it is for option orders specifically, leaving the agent without usage context.

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