ebay_create_or_replace_product_compatibility

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

With no annotations, the description must disclose behavioral traits. It hints at upsert behavior ('create or replace') but does not explain whether replacement is total or partial, or mention dependencies (e.g., item must exist). Lacks details on idempotency, effects on existing data, or required permissions.

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?

Single, clear sentence with no unnecessary words. Could be more informative while staying concise, but currently efficient.

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 simple CRUD tool with no output schema, the description is adequate but incomplete. Lacks behavioral transparency and usage guidance, which are needed given no annotations. Not fully informative for an AI agent.

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 description adds limited value. It confirms the 'body' is a compatibility request, but the schema already describes it. The description does not elaborate on parameter constraints or format 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 identifies the action (create or replace) and resource (product compatibility for an inventory item). It distinguishes from siblings like get and delete, but could be more specific about the domain (e.g., automotive fitment).

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_get_product_compatibility or ebay_delete_product_compatibility. The description does not specify prerequisites or context for creation/replacement.

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