ebay_update_campaign_identification

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

No annotations are provided, and the description only says 'Update campaign identification' without disclosing side effects, required permissions, rate limits, or what exactly gets updated. The burden falls entirely on the description, which 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 a single sentence, but it is underspecified. While concise, it fails to provide necessary details, making it more of a placeholder than a helpful explanation.

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?

Given that this is a mutation tool with no output schema, no annotations, and many similar sibling tools, the description is incomplete. It lacks information about return values, error cases, and practical usage context.

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 description coverage is 100%, so baseline is 3. The schema descriptions are minimal (e.g., 'campaignId required endpoint parameter'), and the tool description adds no extra meaning. The request object only contains campaignName, but the description doesn't clarify its role.

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 'Update campaign identification' which is a verb+resource pair, but it is vague about what 'identification' means (e.g., campaign name or ID). It does not distinguish from many other update tools among siblings.

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 other update tools (e.g., ebay_update_campaign_budget, ebay_update_item_promotion). There are no prerequisites or contextual hints.

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