Create sync product

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

Annotations declare readOnlyHint=false and openWorldHint=true, so the agent knows this is a write operation with external effects. The description adds a genuinely useful behavioral fact — the same file URL is applied to every variant — which clarifies blast radius. However, it says nothing about side effects, required auth/store scoping, or whether the product becomes live.

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?

Two sentences, front-loaded with the core operation and the required inputs, then the key scoping note. No wasted words.

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?

A mutation tool with no output schema, and the description covers inputs but not return values or post-creation state. Since there's no output schema, the description should say what comes back (product id, sync product object) — that gap matters for an agent that needs the id to continue the workflow.

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 67%, above baseline, and the description reinforces the file_url/placement/variant_ids relationship. But it doesn't explain retail_price (decimal string) or thumbnail_url at all, both of which are documented sparsely in 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?

Specific verb+resource: creating a sync product from catalog variant ids, a print-file URL, and a placement. It explains the key semantic (one file URL applied to every variant). It doesn't differentiate from siblings like upload_file or create_mockup_task, but the purpose itself is 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?

No explicit when-to-use guidance, no prerequisites, no alternatives named. An agent can infer this is the creation step in the sync-product workflow, but nothing states when to prefer it over upload_file or when a mockup task should come first.

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