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

The description only states that it deletes, which implies a mutation. No information is given about idempotency, required permissions, side effects, or return behavior. With no annotations to provide safety signals, this is insufficient.

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 extremely concise at one sentence. It is front-loaded with the action and resource. While brief, it could benefit from slightly more context without becoming verbose, but it is not overly terse.

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 operation with no output schema, the description is minimal. It does not address what happens upon success or failure, whether the keyword must exist, or if the operation is reversible. This leaves the agent with unanswered questions.

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 covers 100% of parameters with basic descriptions. The tool description adds no extra meaning beyond what the schema provides, so the baseline score 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 verb 'Delete' and the resource 'campaign-level negative keyword'. It is specific enough to distinguish from keyword-level or ad-group-level operations, but does not explicitly differentiate from the bulk version (ebay_bulk_delete_campaign_negative_keywords).

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?

No guidance is provided on when to use this tool versus alternatives like the bulk delete tool or update tool. The description does not mention prerequisites or scenarios, leaving the agent to infer context from the name alone.

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