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

With no annotations, the description carries full behavioral burden. It discloses that the removal is permanent, which signals irreversibility, and specifies 'owned WEBPAGE' as a constraint. However, it does not clarify that this is only a preparation step (no actual mutation occurs) or what the output/next steps are. It adds some value but leaves key behavioral context implicit.

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 gets straight to the point. It is front-loaded with the action and resource. No wasted words, though it could be slightly more informative without losing conciseness.

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 two-parameter tool with no output schema, the description covers the essential purpose and scope. However, it omits the two-phase workflow context (prepare vs. confirm) and any mention of expected return values or side effects beyond permanence. Given the existence of a confirm sibling, this is a notable gap for an agent to correctly sequence its actions.

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 50%: customer_id has a description, but conversion_action_id is undocumented. The description adds only a hint that the action must be 'owned WEBPAGE', which partially clarifies the id's expected type, but it does not elaborate on the id's format or constraints (e.g., the maxLength). It fails to compensate for the missing schema description of conversion_action_id.

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 (Prepare) and resource (permanent removal of one owned WEBPAGE conversion action). It distinguishes from confirm-step siblings by the word 'Prepare', though it doesn't explicitly reference the two-phase pattern. The specificity of 'owned WEBPAGE' helps narrow scope beyond generic conversion action tools.

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?

No guidance on when to use this tool versus alternatives. It doesn't mention that this is a prepare step requiring a subsequent confirm call, nor does it reference the sibling remove_confirm tool. An agent is left to infer the workflow from the naming convention.

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