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

With no annotations provided, the description carries the full burden. It notably discloses the expected_updated_at concurrency guard, refusal if the product changed, required manager approval per call, one-time sending on approval, and no standing grant. This is unusually transparent about approval and safety behavior.

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 starts with a crisp definition and the includes necessary details about approval and concurrency. It is slightly verbose in the approval/routing section, but every detail serves a real purpose.

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 no-annotation, no-output-schema state-changing tool, this description covers the trigger condition, concurrency requirement, approvalr governed, side-effect behavior, and route. An agent knows what to do, what to provide, and what constraints apply, enough to invoke it correctly.

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?

Although schema coverage is 100%, the description adds critical semantic context for expected_updated_at, explaining that it must come from the reviewed read and that mismatches cause refusal. Product_id and companyId are not expanded in the description, but the schema already describes them adequately.

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 precisely states the action: publishing a draft Shopify product to live buyers with status transition to ACTIVE. It clearly differentiates from siblings like update_live_shopify_product, update_shopify_product_draft, and unpublish_shopify_product by targeting the draft-to-live transition.

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?

It declares when to use: when an operator green-lights a drafted product going live, and the description notes that it requires an approval review. However, it does not explicitly name alternatives or state when not to use this tool, leaving some routing to inference.

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