cancel_fiat_withdrawal

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

Without annotations, the description carries full burden for behavioral transparency. It implies a destructive/mutative action but does not disclose side effects, approval requirements, idempotency, or error scenarios (e.g., what happens if withdrawal is already processed).

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 extremely concise (one sentence plus args) with no redundant information. However, it may be too sparse; including a brief note on behavior (e.g., only for pending withdrawals) could improve it without adding much length.

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 mutation tool with an output schema, the description does not explain the return value or success/failure indicators. It also omits the prerequisite that the withdrawal must be in 'pending' status. The output schema exists but its contents are not described, leaving the agent guessing about the response.

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 has 0% description coverage, so the parameter meaning relies entirely on the description. It states 'withdrawal_id: The withdrawal ID to cancel', which adds basic usage context beyond the schema's type and name, but lacks details on source of the ID, format constraints, or validation rules.

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 the action 'Cancel' and the resource 'a pending fiat withdrawal', specifying the required state. It distinguishes itself from sibling tools like 'cancel_order' by focusing on fiat withdrawals rather than orders.

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 like 'cancel_order'. It does not mention prerequisites (e.g., withdrawal must be pending) or exclusions (e.g., cannot cancel processed withdrawals).

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