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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds no context beyond restating deletion — no permanence warning, no mention of whether products referenced by invoices/estimates can be removed, no effect on related records. It repeats what the annotations and name already convey.

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 short sentences, front-loaded with the action and resource, with zero filler. It is thin rather than bloated, so structure is fine but substance is minimal.

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 one-parameter destructive tool with full annotation coverage and full schema coverage needs little explanation, so this is close to adequate. However, for an irreversible catalog deletion, the missing dependency/cascade information is a real gap an agent would benefit from.

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?

Only one parameter and schema description coverage is 100% ('Product ID to delete'). The description's 'Requires the product ID' merely restates the schema, adding no format or source hints (e.g., where an ID comes from), so baseline 3 applies.

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?

States a specific verb and resource: 'Delete a product/service from the catalog.' The resource is distinct from sibling deletes (delete_invoice, delete_customer, etc.), so no sibling disambiguation is strictly needed, though no sibling is named.

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 when-to-use or when-not-to-use guidance. 'Requires the product ID' is a precondition, not usage guidance. Nothing tells the agent whether to prefer update_product over deleting, or what state the product must be in.

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