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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the mutation/safety profile is covered. The description adds no behavioral context beyond the workflow framing: it never says the live conversion action is mutated, that the change is irreversible, whether the draft is consumed, or what happens when confirmation fails.

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 front-loaded sentence with no filler; the object of the action and its scope are immediately clear.

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 mutation with no output schema and two undocumented parameters, the description is too thin. An agent cannot tell what confirming applies, whether it is reversible, or how to recover from a failed/expired draft.

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% — customer_id is documented but draft_id and connection_context are not. The description only alludes to 'one prepared ... draft', giving no format, source, or lifetime for draft_id and no explanation of connection_context, so it 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?

States a specific verb (Confirm) and a specific resource (a prepared WEBPAGE conversion-action update draft), scoping it to one draft, one action type. It is distinguishable from its prepare counterpart by the verb alone, though it never names the sibling explicitly.

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 phrase 'prepared ... draft' implies the confirm step must follow a prior prepare call, which is useful implied workflow guidance. There is no explicit when-to-use/when-not, no stated alternative, and no mention of what to do if the draft is stale or missing.

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