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

No annotations are provided, so the description bears the full burden, and it discloses almost nothing: permanence of deletion, referential effects (e.g., a product referenced by existing invoices), required permissions, and error behavior on an unknown ID are all unstated.

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?

One short, front-loaded sentence with no filler, which is appropriate for a single-parameter tool. It is terse to the point of under-specification, but that is penalized under completeness rather than here.

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 destructive one-parameter mutation with no annotations and no output schema, the description says nothing an agent needs beyond the operation name — no confirmation of what happens on success/failure or what collateral effects deletion has.

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 coverage is 100%, and the single parameter is documented in the schema as a Product ID sourced from search_products. The description's 'by ID' adds nothing beyond that, so the baseline of 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 (delete) and resource (product) with the identifying key (ID). It is unambiguously distinguishable from siblings such as delete_client or delete_invoice, though it does not explicitly contrast with update_product.

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?

There is no guidance on when to use this versus update_product or search_products, no prerequisites, and no mention of confirmation or irreversibility. The only hint of context is the schema note that the ID comes from search_products.

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