ga4_delete_event_create_rule

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

With no annotations, the description carries the burden. It discloses the destructive nature ('delete') and the safety mechanism (confirm flag and config). However, it does not clarify irreversibility, permissions, or error states, which are relevant for a delete operation.

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 a single, concise sentence that includes all necessary elements: action, resource, and prerequisites. It is efficient and front-loaded with the action, leaving no wasted words.

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?

For a simple delete tool with two parameters, the description is adequate but lacks details on post-deletion behavior, error handling, or permissions. Given no output schema and no annotations, the description could provide more context to be fully complete.

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 baseline is 3. The description does not add any parameter information beyond what the schema already provides, so it neither adds nor detracts.

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 verb 'Delete' and the resource 'event-create rule', distinguishing it from other sibling delete tools by specifying the exact resource type. The '[GA4 DELETE]' prefix and the prerequisite details add clarity.

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?

The description explicitly mentions the required environment variable and confirm parameter, providing clear context for usage. However, it does not discuss alternatives or when not to use this tool relative to other delete tools, though the resource name itself differentiates.

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