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

Annotations already declare that the tool is non-read-only, open-world, idempotent, and destructive. The description adds a preview/confirmation workflow and requestId reuse, which is useful, but it is cryptic and mentions spending/deletion for a rename operation without clarifying what is destructive or what auth is required.

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 short and front-loads the purpose. The trailing "Fields: soclo://tools/..." fragment is unclear and does not earn its place, but the overall definition remains concise.

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 10-parameter, nested mutation tool with no output schema, the description is too thin. It omits key input semantics and does not explain the expected* preview fields, what the tool returns, or how errors/recovery work.

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?

With 10 parameters and only 60% schema description coverage, the description should clarify the undocumented required inputs. Instead it only mentions confirm and requestId, which are already documented in the schema, and does not explain parameters.creativeId, payload.name, accountId, or the platform field.

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 states a specific verb and resource: "Rename a creative." That distinguishes it from create/delete/list creative tools, but it does not explicitly differentiate it from nearby update tools such as soclo_ads_update_ad or explain its exact scope.

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?

It includes procedural guidance for spending/deletion operations: preview, owner-approved confirm:true, and reuse the same requestId. However, it does not clearly say when to use this tool versus alternatives, nor does it explain whether that confirmation workflow actually applies to a pure rename.

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