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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description does add meaning beyond that by stressing 'permanent removal' of exactly 'one' action, but it omits any warning that the operation is irreversible or what happens to the referenced draft.

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?

A single tight sentence with the key constraint ('permanent') front-loaded and zero filler. Nothing could be trimmed without losing information.

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 destructive confirm step with no output schema and two undocumented parameters, the description is adequate but thin. It establishes the action and its permanence, yet omits the prerequisite prepare step and the meaning of draft_id, leaving gaps an agent must infer.

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 only 33% (only customer_id is documented) and the description supplies nothing about draft_id or connection_context. The agent gets no explanation of where draft_id comes from or that it references the prepared mutation, so the description fails to compensate for the coverage gap.

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 names a specific verb (confirm permanent removal), the resource (conversion action), and scopes it to a single prepared WEBPAGE conversion action. It implicitly pairs with the remove_prepare sibling via 'prepared', though it never names that sibling outright.

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?

Usage is only implied: 'prepared' hints this is the second half of a prepare/confirm workflow, but the description never states that a prior google_ads_conversion_action_remove_prepare call is required, nor when not to call it. No alternatives are named.

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