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

No annotations are provided, so the description carries full burden. It mentions '需 API Key' (requires API Key), which is a minor auth hint, but does not disclose whether this is a read-only operation, what data is returned, rate limits, or any side effects. For a zero-parameter overview tool, this is a significant gap in behavioral context.

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 a single, compact sentence that front-loads the core purpose and includes the key requirement. It is efficient with no waste, though slightly cryptic in wording.

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?

Given no annotations, no output schema, and zero parameters, the description is thin. It does not explain what the overview contains in detail, how it is structured, or what an agent should expect. It mentions an API Key requirement but leaves many aspects incomplete for correct 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?

Parameter count is 0, so the baseline is 4. The description correctly indicates no parameters are needed and adds no confusing parameter information.

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 states it is a master account overview covering orders/pages/entrustments/intentions, giving a general sense of the resource. However, it does not clearly distinguish itself from siblings like zengzhi_my_market or zengzhi_report_orders, which also appear to deal with user-specific data. The purpose is implied but not sharply defined.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention scenarios, prerequisites beyond an API Key, or exclusions. The agent must infer usage from context alone.

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