google_ads_campaigns_update_status

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

With no annotations, the description covers key behaviors: lightweight (writes only status), return fields, ENABLED↔PAUSED reversibility via rollback_apply, and REMOVED reversal within 30 days. No contradictions.

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?

Four concise sentences, each with distinct information: purpose, scope, returns, reversibility, and sibling differentiation. No filler.

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?

Provides return values and reversal details despite no output schema. Could mention error conditions or permissions, but given simplicity, it's largely sufficient.

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 covers 100% of parameters with clear descriptions. The description adds value by explaining reversibility per status value and fallback behavior for customer_id, slightly enhancing understanding.

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 tool sets the delivery status of a single campaign to ENABLED, PAUSED, or REMOVED, which is specific and distinct from siblings like google_ads_campaigns_update that handle other settings.

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: 'Use this for pause/resume; use google_ads_campaigns_update to change name, bidding, or other settings.' Also explains reversibility and soft delete behavior.

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