approve_trade

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does disclose that approval 'executes immediately', which is a key behavioral trait, and notes it is only relevant in confirm mode. However, it does not elaborate on side effects, irreversibility, or required permissions for this potentially consequential action.

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?

Two short sentences, front-loaded with the core purpose and followed by the key usage constraint. Every word earns its place with no redundancy or filler.

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 a single parameter and an output schema, the description provides the essential purpose and the conditional context (confirm mode). It does not explain what happens after execution or prerequisites, but given the tool's simplicity and sibling context, it is reasonably complete.

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?

Schema description coverage is 0% and there is one required parameter. The description indirectly explains that decision_id refers to a 'pending trade decision', providing some meaning beyond the parameter name. But it stops short of giving format, origin, or how to obtain the ID, so it only partially compensates for the missing schema descriptions.

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 verb 'approve' and the resource 'pending trade decision', and adds that it executes immediately. This distinguishes it from sibling tools like reject_trade and place_order, as it specifically handles pending trade decisions.

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 explicitly states when this tool is needed ('Only needed in confirm mode'), and implies it is not needed outside that mode. However, it does not mention alternative tools (e.g., reject_trade) or provide explicit when-not guidance, so it falls short of a 5.

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