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

Annotations provide no hints (all false), so the description carries the full burden. It discloses negative behaviors (does not create checkout, invoice, etc.) but does not explain what happens when the link is created, whether it persists, or if any state changes occur. The 'human review' aspect is mentioned but not fleshed out.

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 tight sentences: the first states the core purpose, the second clarifies boundaries. All words earn their place, and the crucial action ('Create a human review link') is front-loaded. No fluff or redundancy.

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 tool is simple (3 params, 1 required) but the description omits essential context: what a 'human review link' does, how it relates to the paid-depth options, and what the optional params (address, request_id) are for. An agent cannot reliably construct a correct call because the description does not explain the required offer_key or the purpose of the other fields.

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%, so the description must compensate, but it does not. It vaguely references 'selected AliEV paid-depth option' (likely offer_key) but fails to explain any of the three parameters: offer_key (required), address, and request_id. An agent gets no guidance on what values to provide or why these parameters matter.

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 uses a specific verb ('Create') and resource ('human review link for a selected AliEV paid-depth option'), clearly distinguishing it from sibling analysis/retrieval tools. It also explicitly lists what it does NOT do (checkout, invoice, etc.), which sharpens the purpose.

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 phrase 'for a selected AliEV paid-depth option' implies the agent must first have an offer key, but it never explicitly says when to use this tool over siblings or what prerequisites are needed. There is no mention of alternatives or exclusion criteria, leaving usage context only inferred.

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