google_ads_create_campaign

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

The description discloses that the default status is PAUSED 'for safety', implying it creates campaigns without immediate activation. However, it does not explain side effects, required permissions, or cost implications. With no annotations, more behavioral context would be beneficial.

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 uses a clean bullet-point list for parameters and a brief return statement. It is front-loaded with the purpose and each line is specific. It is slightly long but appropriate for 13 parameters.

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?

All parameters are explained, but missing high-level context such as error handling, prerequisites (e.g., billing), or how to choose between this and specialized creators. The return value is vague.

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?

The description adds useful meaning beyond the schema titles: e.g., customer_id format, budget example, conditional parameters for bidding strategies. Since schema description coverage is 0%, the description compensates well.

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 'Create a new Google Ads campaign' and enumerates all parameters. However, it does not differentiate from sibling tools like google_ads_create_performance_max_campaign or google_ads_create_shopping_campaign, which have more specific purposes.

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 explicit guidance on when to use this tool versus the many specialized campaign creation tools. It does not mention prerequisites, when not to use it, or alternatives.

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