list_campaign_groups

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

No annotations exist, and the description does not disclose any behavioral traits such as pagination, sorting, filtering behavior, rate limits, or what exactly a 'campaign group' entails. The agent gets no insight into side effects or operational 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 very concise at 6 words, but it is too brief for the complexity of the tool. It is front-loaded but does not earn its place by providing enough context for correct invocation.

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 number of parameters (7), lack of parameter descriptions, no output schema, and many sibling tools, the description is completely inadequate. It fails to explain what a campaign group is, how to use parameters, or what the response contains.

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?

With 0% schema description coverage, all 7 parameters are left entirely undocumented. The description adds no information about any parameter, failing to compensate for the missing schema descriptions. This is a critical gap.

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 the action (List) and resource (campaign groups) and specifies scope (for an ad account). However, it does not differentiate from sibling tools like list_campaigns or list_creatives, which also list similar resources.

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 vs alternatives. The agent is left to infer from the name, but with many sibling tools, explicit when-to-use or when-not-to-use instructions are missing.

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