ebay_update_campaign_identification

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

As a mutation tool with no annotations, the description should disclose side effects or requirements, but it only says 'Update'. No mention of permissions, reversibility, or what happens on failure.

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 concise sentence, but it lacks structure and is vague. It front-loads the verb but does not provide useful detail.

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?

No output schema is provided, but the description fails to explain what the tool returns. It also omits prerequisites like campaign existence or user permissions, making it incomplete for an update operation.

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%, so baseline is 3. The description adds minimal value beyond the schema: it groups parameters under 'identification details', but the schema already describes campaignName 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 clearly states it updates campaign identification details, specifically name. However, it vaguely mentions 'other identification details' which are not present in the schema, slightly reducing clarity.

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 on when to use this tool versus alternatives like ebay_update_campaign_budget or ebay_update_campaign_negative_keyword. The description lacks any context about appropriate scenarios.

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