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

The annotations already indicate destructiveHint=true and readOnlyHint=false, and the description adds no further behavioral context such as permanence, cascading deletions, or auth requirements. It is consistent with the annotations but does not go beyond them.

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 core description is appropriately short, but the 'Guidance' sentence is redundant and does not earn its place. The structure is not harmful, yet it contains unnecessary repetition.

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 delete operation with a single required identifier and no output schema, the description plus annotations are complete enough for an agent to invoke the tool. It does not explain consequences, but destructive behavior is already flagged.

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 product_id parameter is fully covered by the schema with the description 'Product Unique ID.' The description adds no additional semantic detail, but the schema coverage is complete and unambiguous for a simple identifier.

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 'Deletes' and the resource 'specific product', making the tool's purpose unambiguous. It does not explicitly differentiate among the many sibling delete tools, but the resource name product is distinct enough within the shop_ namespace.

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 shop_delete_option or shop_delete_variant. The repeated 'Guidance' line merely restates the action and adds no decision-making context.

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