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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the safety profile is known. The description adds one useful behavioral detail – that the call reads back the copy on the same Ad ID after confirming – but omits what specifically changes, reversibility, or auth requirements.

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 compact sentence with the confirmation action front-loaded and the read-back behavior trailing. Nothing is wasted, though the sentence is terse enough to feel slightly under-specified rather than optimally dense.

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?

An output schema exists, so return-value explanation is not required, and the read-back note covers the response shape informally. Still, for a destructive confirm operation with 0% parameter coverage and no stated preconditions, the description leaves real gaps.

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 0%, so the description must carry parameter meaning, and it does not. Neither confirm_token (how it is obtained, its lifecycle) nor connection_context is explained, leaving the required parameter entirely opaque.

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 resource (approved copy edits), plus an extra behavioral note ('read back copy on the same Ad ID'). The 'confirm' framing clearly separates it from the ads_update_copy_prepare/deny siblings, though it never names them 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?

Usage is implied by 'Confirm approved copy edits' – the agent can infer this is the approval step after a prepare flow. However, no explicit when-to-use, prerequisites (e.g., a prior prepare call producing confirm_token), or alternative paths are stated.

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