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

Annotations already mark this as non-read-only, destructive, and open-world. The description adds meaningful behavioral context beyond annotations by explaining the preview/owner-approval gate, confirm:true requirement, requestId reuse, and the condition that the claim is live only when status is active.

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 spending/deletion workflow follows logically, though the final 'Fields: soclo://...' fragment is cryptic and does little work.

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, spending-related creation tool with a complex nested payload and no output schema, the approval workflow is covered well. But important call semantics remain under-explained, especially the payload structure, required fields, and what a successful creation returns.

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?

The schema covers 60% of the 10 parameters, but the description adds little parameter meaning. It mentions confirm and requestId, which are already documented in the schema, and the line 'Fields: soclo://tools/...' is a reference rather than useful explanation of the nested payload or the other undocumented parameters.

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: create a standalone creative. It is clear what the tool does, but it does not distinguish this creative-creation tool from nearby siblings such as soclo_ads_create_standalone_ad or soclo_ads_create_call_ad.

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 description gives procedural guidance for spending/deletion actions: preview, obtain owner approval, then call with confirm:true and the same requestId. However, it does not say when to choose this tool over sibling creative or standalone-ad creation tools.

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