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

No annotations are present. The description does not disclose whether updates are additive or replace, idempotency, or side effects. For a mutation tool, users need to know if missing fields are cleared or ignored.

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 (7 words) but lacks necessary detail. Conciseness is positive, but it sacrifices completeness, making it insufficient for complex tools.

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?

The tool has a nested input schema with required fields and an enum, yet the description is minimal. No output schema exists, so more detail on update behavior, response format, or error conditions is needed.

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?

Schema coverage is 100% with basic descriptions. The description adds no extra meaning beyond the schema. Baseline score of 3 is appropriate as schema already defines parameters clearly.

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 'Update multiple ad group-level negative keywords' clearly states the action (update), resource (ad group-level negative keywords), and bulk nature. It is specific enough to distinguish from create/delete operations but does not explicitly differentiate from single update sibling.

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 ebay_update_ad_group_negative_keyword or bulk creation. There is no mention of prerequisites, limitations, or context for optimal use.

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