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

With no annotations, the description carries the full behavioral burden. 'Permanently' usefully signals irreversibility, but it omits permissions required, whether deletion cascades to related records, and whether the operation fails or is blocked under certain states.

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?

A single short sentence with the key qualifier ('Permanently') front-loaded and no filler. Nothing could be trimmed without losing content.

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, irreversible operation with no annotations, no output schema, and 0% parameter documentation, this description is far too thin. It should at minimum state permissions, side effects, and failure conditions.

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 0% for the single product_id parameter, and the description adds no format, source, or lookup guidance. The parameter's meaning must be guessed entirely from its name.

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') with the adverb 'Permanently' narrowing the operation. However, it does not distinguish itself from siblings like update_product, get_product, or list_products, nor does it clarify the delete semantics relative to any archival alternative.

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 guidance on when to use this tool versus alternatives such as update_product, nor any preconditions (e.g., whether the product must have no active subscriptions or orders). The agent must infer everything about invocation context.

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