ebay_bulk_update_ads_status

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

With no annotations, the description carries full burden for behavioral details. It only states the basic action (update status) and campaign type constraint. No information about destructive nature, reversibility, partial failure handling, permissions, rate limits, or response behavior is provided. This is insufficient for a mutation tool.

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, containing only two short sentences with no unnecessary words. Every element (verb, resource, constraint) is purposeful and front-loaded, making it easy to scan.

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 the tool's complexity (bulk operation with nested objects, no output schema), the description is too minimal. It lacks information about execution behavior, error handling, expected results, and prerequisites. The campaign type constraint is helpful but insufficient for complete understanding.

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 has 100% coverage, so the baseline is 3. The description adds value by specifying that updates are only for CPC priority strategy campaigns, which is a constraint on the campaignId parameter not present in the schema. No additional details are provided for adId or adStatus beyond the schema.

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 (update status) and resource (multiple ads), with a specific campaign type constraint (CPC priority strategy). This distinguishes it from similar tools like ebay_bulk_update_ads_status_by_listing_id, though it could be more explicit about the identification method (by ad ID vs. listing ID).

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 provides important context by restricting usage to 'CPC priority strategy campaigns only,' which helps the agent understand when to use this tool. However, it does not mention when not to use it or provide alternatives like ebay_bulk_update_ads_bid_by_inventory_reference for other scenarios.

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