ebay_publish_offer_by_inventory_item_group

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

The description adds the required OAuth scope but omits side effects (e.g., listing activation, overwrite behavior), prerequisites (e.g., existing offer), and return value. Without annotations, the burden falls 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 extremely concise: two sentences stating the action and OAuth scope. No fluff, front-loaded with the purpose. Every word earns its place.

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 no output schema and no annotations, the description should provide more context (e.g., prerequisites, effect on existing listings, error conditions). It only gives OAuth scope. This is insufficient for a mutation tool.

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 reported as 100%, but only the request object has a description; individual properties lack descriptions. The tool description adds no parameter-level info beyond the schema. The parameter names are somewhat self-explanatory, so baseline 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 tool publishes an offer for an inventory item group (variation listing). The verb 'publish' and resource 'offer for inventory item group' are specific. However, it does not explicitly differentiate from sibling tools like ebay_publish_offer or bulk versions, though the name and parenthetical hint at it.

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 (e.g., ebay_publish_offer for single items or bulk publish). The description only lists required OAuth scopes, which is not usage guidance.

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