ebay_publish_offer_by_inventory_item_group

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

With no annotations, the description must fully disclose behavioral traits. It states 'Publish an offer' implying a write/mutation operation but does not describe side effects, required prior state, error conditions, or the outcome (e.g., creating an eBay listing). The OAuth scope is provided but insufficient for understanding the tool's impact.

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 short (two sentences) and includes only essential information: purpose and OAuth scope. No unnecessary words. However, it could be slightly improved by integrating the scope into the first sentence or using a clearer structure (e.g., separating purpose and prerequisites).

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?

For a publish action with minimal schema and no output schema, the description should cover prerequisites, what the body should contain, and the return value. It fails to provide context on how to construct the body, what a successful publish returns, or how this differs from similar tools. Significant gaps remain.

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 parameter description ('Generated PublishByInventoryItemGroup body') is generic and adds no meaningful guidance beyond the schema. While schema coverage is 100%, the single parameter's description does not hint at required fields, structure, or constraints. The agent gains no additional insight from the description.

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 ('Publish an offer') and the resource ('inventory item group') with an explanatory parenthetical ('variation listing'). This distinguishes it from sibling tools like ebay_publish_offer (single offer) and ebay_withdraw_offer_by_inventory_item_group. The purpose is specific and unambiguous.

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 lists the required OAuth scope but provides no guidance on when to use this tool versus alternatives like ebay_publish_offer or ebay_bulk_publish_offer. There is no mention of prerequisites (e.g., the offer must be created first via ebay_create_offer) or situations where this tool is inappropriate.

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