google_ads_update_campaign

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

No annotations provided. The description does not disclose side effects, permissions needed, or whether optional fields update incrementally or require full specification. The return value description is minimal ('Success message with updated fields').

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 one-line purpose followed by a structured argument list. It avoids unnecessary prose, fitting the 6-parameter tool well.

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?

Covers all parameters and return type but lacks examples, error handling, or behavior on omitted fields. Given an output schema exists but is unused, the description is adequate but not comprehensive.

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 coverage is 0%, so the description fully carries parameter meaning. It lists all 6 parameters with explanations, including format hints (e.g., 'YYY-MM-DD'), allowed status values, and optionality. However, it does not explicitly mark customer_id and campaign_id as required, which the schema shows.

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 'Update campaign settings' with a specific verb and resource. Among siblings like google_ads_update_campaign_status_v2, this tool covers multiple settings (name, status, dates), distinguishing it from more specific update tools.

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 vs alternatives such as google_ads_update_campaign_status_v2 or google_ads_update_campaign_budget_v2. The description does not mention context or prerequisites.

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