sellfox_ads_sp_keywords

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

No annotations provided, so the description carries full burden. It does not disclose whether the tool is read-only, returns paginated results, or requires specific permissions. Only says 'basic data', which is insufficient for behavioral understanding.

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?

Extremely concise (one short sentence) but at the cost of necessary information. Not front-loaded with actionable content; it does not earn its place as it fails to communicate essential details.

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?

No output schema, so description should explain return values. It does not. For a 4-parameter tool, the description lacks completeness regarding behavior and results. The sibling tools indicate many similar SP tools, but no comparative context is given.

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 100%, so baseline is 3. The description adds no extra meaning beyond the schema parameter descriptions. It does not provide usage examples or clarify 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 'SP关键词投放基础数据' is a noun phrase lacking a verb. It vaguely states the subject (SP keyword delivery basic data) but does not clarify the action (e.g., list, get, query). It fails to distinguish from siblings like sellfox_ads_sp_negative_keywords or sellfox_ads_sp_targets.

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 on when to use this tool versus alternatives. No context on filtering, prerequisites, or typical use cases. The description provides no usage direction.

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