get_product_change_notifications

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

Annotations already declare readOnlyHint=true and idempotentHint=true, covering the safety profile. The description adds some context about the data (raw API dates, diagnostics) but is vague and does not mention limitations or response structure. It adds marginal value beyond annotations.

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 11-word sentence, extremely concise and front-loaded with 'Get PCNs.' However, the phrase 'additive description-date diagnostics' is jargon-heavy and may obscure meaning, making it slightly less effective than it could be.

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?

With no output schema and sparse parameter descriptions, the description should explain return content and parameter effects. It only hints at raw dates and diagnostics, and the 'includes' parameter is undefined, leaving the tool insufficiently specified for reliable 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?

The schema has zero descriptions for parameters and the description mentions neither product_number nor includes. The optional 'includes' parameter is completely unexplained, leaving the agent without any clue about its purpose or valid values. With 0% schema coverage, the description fails to compensate.

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 clearly identifies the tool as retrieving Product Change Notifications (PCNs) and adds specifics about raw API dates and additive diagnostics. It is distinct from sibling tools which focus on pricing, products, orders, or other domains.

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?

The description gives no explicit guidance on when to use this tool versus alternatives. It does not mention that it is the only PCN-related tool or contrast it with other getters like get_product_details, leaving the usage context unclear.

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