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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It offers no information about safety, destructive potential, authorization needs, rate limits, or return format, leaving the agent completely uninformed about the tool's behavior.

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 short (one line), which is concise but lacks substantive content. While it avoids verbosity, it does not earn its place as it fails to inform beyond the title.

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 the high parameter count (20), no output schema, and no annotations, the description is gravely incomplete. It does not explain the return structure, any constraints, or how to interpret results, making it inadequate for an agent to use effectively.

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?

All 20 parameters have descriptions in the input schema (100% coverage), so the baseline is 3. The tool description adds no additional meaning beyond the schema, failing to provide context or inter-parameter relationships.

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 explicitly states '结算利润-ASIN维度(V2)', which clearly indicates it deals with settlement profit at the ASIN level. While it conveys the resource and dimension, it does not differentiate from similar sibling tools like sellfox_settlement_profit_shop or sellfox_profit_report_asin.

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. The description lacks context about suitable scenarios, prerequisites, or exclusions, leaving the agent without direction for appropriate invocation.

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