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

With no annotations, the description carries the full burden of disclosing behavioral traits. It only states the action and target; it does not mention required fields, validation behavior, duplicate handling, defaults, side effects, or return values. This is minimal behavioral disclosure.

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 is a single, front-loaded sentence with no fluff, but it is under-specified for a tool with 9 parameters. It is concise structurally yet lacks the detail needed to be considered well-rounded.

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?

Given the tool has 9 parameters, low schema coverage, no output schema, and no annotations, one sentence is insufficient. The description does not address required inputs, defaults, uniqueness, or what happens after the product is added, leaving significant gaps for safe invocation.

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 only 22%, so the description must compensate by explaining parameter meaning. It does not mention id, name, price, sku, stock, status, category, description, or manufacturer, leaving most parameters effectively undocumented from the agent's perspective.

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 uses a specific verb ('Add'), identifies the resource ('a product'), and names the target context ('Excel catalog'). This clearly distinguishes it from sibling tools like list_products, search_products, update_product, and delete_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?

No guidance is provided about when to choose this tool over alternatives, prerequisites, or uniqueness constraints. The verb 'Add' implies the basic use case, but the description offers no explicit when-to-use or when-not-to-use context.

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