ebay_delete_campaign

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

With no annotations, the description carries full burden. It discloses permanence and irreversibility, but doesn't mention required permissions, effects on dependent resources (e.g., ads, keywords), or any scoping constraints. Adequate but could be richer.

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?

Two short, front-loaded sentences. Zero waste. Every word earns its place. Highly concise and well-structured.

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 delete tool with one parameter and no output schema, the description provides essential context (action, permanence). Slightly more detail on prerequisites or side effects would push to 5, but it's still fairly complete.

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?

Only one parameter (campaignId) with schema description 'Campaign ID'. The tool description adds no extra meaning beyond the schema. Since schema coverage is 100%, baseline of 3 is appropriate.

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 action 'Permanently delete' and the resource 'marketing campaign'. This distinguishes it from siblings like ebay_end_campaign (which may only end) and ebay_pause_campaign, making the purpose precise.

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 implies use for permanent removal with 'cannot be undone', but lacks explicit guidance on when to use this over alternatives like ebay_end_campaign or ebay_pause_campaign. No when-not-to-use or alternative mentions.

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