add_product

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

No annotations are provided, and the description does not disclose behavioral traits such as duplicate handling, authentication requirements, or side effects like triggering initial price checks. For a creation tool, this is a critical omission.

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 sentence, making it concise but at the expense of necessary detail. It is front-loaded with the main action but lacks structure for completeness.

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 5 parameters, no annotations, and an output schema, the description is incomplete. It does not explain the purpose of each parameter, the return value, or post-add behavior. The agent would need to infer too much from parameter names alone.

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% and the description does not explain any parameters. While some parameter names are self-explanatory (e.g., url, notify_on_sale), the description adds no value beyond the schema, leaving agents without guidance on format or usage constraints.

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?

Description clearly states the action (add) and object (retail product URL) and destination (tracker), distinguishing it from siblings like remove_product or check_product. However, it does not specify the tracker's purpose (price tracking) or clarify that the tool adds a new product to monitor.

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 like check_product or list_products. The usage context is implied (adding new products), but there is no explicit when-not or mention of prerequisites.

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