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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the core safety profile is known. The description adds plan/admin eligibility, but does not explain irreversibility, what confirm/dry_run do, or what happens if the rule is missing—all important for a destructive 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?

Two short sentences with no filler and the action front-loaded. It is concise, though its brevity contributes to the missing parameter and behavior detail.

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 34 undocumented parameters, no required fields, a destructive operation, and a large optional schema, the description is far too thin. The output schema reduces the need to explain return values, but critical input and safety behavior remain unaddressed.

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?

There are 34 parameters with 0% schema description coverage, and the description names none of them. It does not clarify which parameter identifies the rule (rule_id), what dry_run or confirm do, or why unrelated parameters such as campaign_id or date_from exist on a delete tool.

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?

States a specific verb (Delete) and resource (SEO/AEO alert rule), clearly distinguishing it from upsert/list siblings by operation. It does not explicitly contrast with automate_delete_alert_rule or automate_delete_automation_rule, but the resource name is specific enough.

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?

Mentions the Admin and Starter+ eligibility prerequisites, which is useful. However, it gives no guidance on when to use it versus listing or upserting rules, nor on whether rule_id must exist or whether dry_run/confirm should be used first.

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