get_bid_suggestion

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

No annotations are provided, so the description carries the full burden. It mentions historical performance and competition analysis, which gives some context, but it does not disclose whether the tool is read-only, any authentication requirements, or side effects. The behavior is partially transparent but incomplete.

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 concise with a clear structure: a short Chinese phrase, then English description, then a list of parameters. It is front-loaded with the purpose. However, the Chinese phrase may be unnecessary for non-Chinese speakers.

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?

For a tool with no output schema and only two parameters, the description is minimal. It does not describe the return format or any additional behavioral details needed for correct usage. The tool is simple, but the description could be more complete.

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%, meaning the description does not explain the parameters beyond listing their names. The args list provides no additional meaning beyond the property titles in the schema. The description should compensate for the lack of schema descriptions but fails to do so.

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 clearly states that the tool gets bid optimization suggestions including recommended bid range. It uses a specific verb and resource, distinguishing its purpose from sibling tools that retrieve raw campaign details or reports.

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 description does not provide guidance on when to use this tool vs. alternatives. With many sibling tools like get_campaign_detail, it is unclear when to prefer this one. No when-not or exclusion criteria are given.

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