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

No annotations are present. The description lacks any disclosure of side effects, permissions, or idempotency traits beyond the obvious deletion. It does not inform the agent about potential irreversible changes or prerequisites.

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 a single, efficient sentence with no wasted words. While not structured with bullet points, it is concise and front-loaded. However, it could benefit from additional context.

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 three required parameters and no output schema, the description is minimally adequate. It does not explain prerequisites, return values, or error conditions, but the operation is straightforward.

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 input schema already provides clear descriptions for all three parameters (campaignId, adGroupId, keywordId) with 100% coverage. The description adds no additional meaning beyond what the schema provides.

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 ('Delete') and the resource ('a specific keyword from a campaign'), distinguishing it from the sibling bulk delete tool. The verb-resource combination is specific and unambiguous.

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 the tool is for deleting a single keyword, but it does not explicitly state when to use it versus the alternative 'ebay_bulk_delete_keywords' or any other context. No when-not-to-use guidance is provided.

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