he_pre_approve_exchange

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

No annotations are provided, so the description carries full burden. It states 'Pre-approve' implying a state change but does not disclose side effects, permissions, or post-approval behavior. The user confirmation instruction adds some transparency but not enough.

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 sentences with no filler: first states the purpose, second is a bolded critical instruction. Every word earns its place.

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 single-parameter tool with no output schema, the description covers the minimum purpose and a critical user-confirmation note. However, it lacks context about the pre-approval flow, whether it is reversible, or what happens after.

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 already describes 'conversationId' as 'Conversation ID' (100% coverage). The description adds no additional meaning beyond what the schema provides, so baseline score applies.

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 'Pre-approve an exchange request' is a specific verb+resource pair, clearly indicating the tool's action. It distinguishes from sibling tools like he_cancel_exchange or he_change_exchange_type.

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 bold instruction 'IMPORTANT: ask user confirmation' provides a critical usage guideline, but it does not offer guidance on when to use this tool versus alternatives or specify the context of the exchange flow.

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