Get product prices

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds useful scoping ('all prices... across all pricelists, currencies, and billing cycles'). However, it does not disclose response format, pagination, or any additional behavioral constraints beyond what annotations and scope imply.

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 redundant words. Every piece ('all prices', 'one product', 'across all pricelists, currencies, and billing cycles') earns its place and directly clarifies the tool's scope.

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 read-only, single-parameter tool, the description adequately covers the scope and outcome. It lacks an explicit return-value description, but the absence of an output schema and the tool's simplicity keep the gap minor. The description would benefit from noting the response is a collection of prices.

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 fully documents product_id as 'Product UUID' (100% coverage). The description adds no new parameter-level detail beyond reinforcing that the tool targets one product. The baseline of 3 applies since the schema already handles parameter meaning.

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 states the tool retrieves all prices for a single product across multiple dimensions (pricelists, currencies, billing cycles). The verb 'Get' and specific resource 'product prices' distinguish it from siblings like get_product or list_pricelists.

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 implies usage when you need comprehensive price data for a specific product, but it does not explicitly mention alternatives or exclusions. There are no siblings that directly compete, so the context is clear but not explicitly guided.

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