sellfox_ads_sd_campaigns

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

With no annotations, the description must fully disclose behavior, but it only says 'basic data'. It does not indicate whether the tool is read-only, requires special permissions, returns a list or a single object, or handles pagination. The agent cannot infer safe or expected 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 brief (4 Chinese characters) but lacks substance. Conciseness should not come at the expense of clarity; here it is under-specified and fails to convey the tool's purpose.

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 absence of an output schema, annotations, and any detailed behavioral description, the tool is critically incomplete. An AI agent cannot determine what data is returned, how to interpret parameters beyond schema basics, or when to use this tool.

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 tool description adds no extra meaning beyond the schema's Chinese parameter descriptions. It does not clarify parameter format, constraints, or 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 'SD广告活动基础数据' is vague: it lacks a verb and does not specify whether the tool retrieves, lists, or performs another action. It does not distinguish from siblings like sellfox_ads_sd_campaign_hourly, which suggests a temporal breakdown, while this tool likely provides a list or summary.

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 (e.g., sellfox_ads_sd_campaign_hourly for hourly data or other campaign tools for SP/SB types). There are no prerequisites or exclusions mentioned.

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