draft_update_catalog_ad_item

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It only says 'update' without detailing whether it is a partial update, whether validation occurs, what the return value looks like, or any side effects. This is a significant transparency gap 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 a single sentence with no unnecessary words and is front-loaded. However, it is quite terse, bordering on under-specification, though that is more a completeness concern than a conciseness one.

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 mutation tool with no annotations and no output schema, the description is incomplete. It does not mention the draft workflow context, how it differs from live catalog ad item updates, or what behaviors to expect, leaving the agent under-informed for tool selection and invocation.

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 already describes both parameters (id and draft) with 100% coverage, so the baseline is 3. The description adds no additional parameter semantics beyond what the schema provides, but it also does not need to because the schema is sufficient.

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 verb 'Update' and the resource 'existing draft catalog ad item', distinguishing it from creation or deletion. However, it closely mirrors the tool name and does not explicitly differentiate from non-draft update tools like update_catalog_ad_item, so it lacks explicit sibling differentiation.

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 no guidance on when to use this tool versus alternatives such as update_catalog_ad_item or draft_create_catalog_ad_item. The draft-specific context is implied by the name but not explained, leaving the agent without clear usage direction.

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