google_ads_keywords_pause

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

With no annotations, the description fully carries behavioral disclosure. It states the operation is non-destructive, preserves quality score and historical stats, returns criterion ID and new status, and is not automatically reversible. This is exemplary transparency for a mutation tool.

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 four sentences, each adding meaningful information: purpose, non-destructive nature, return value, rollback advice, and sibling distinction. It is information-dense without redundancy or fluff.

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?

Despite having no output schema and no annotations, the description covers the operation's purpose, effects, return value, reversibility, and alternatives. For a simple pause tool, it is fully self-contained and does not leave the agent guessing.

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 the baseline is 3. The description itself adds little about the parameters beyond what the schema already documents, but the schema descriptions are complete, so no deduction below baseline is warranted.

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 opens with 'Sets the status of a single keyword criterion to PAUSED', which is a specific verb+resource+state. It distinguishes from the sibling google_ads_keywords_remove by explicitly recommending pause for temporary suspensions, making the purpose unmistakable.

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?

Explicit guidance is provided: 'Use this instead of google_ads_keywords_remove whenever the suspension might be temporary.' It also gives the resumption path via google_ads_keywords_add and advises recording before-state for rollback, making the when-to-use clear.

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