purchases_products_v2_get

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

No annotations provided, so description must carry the burden. It states 'Get current state' indicating a read operation, but does not disclose potential errors (e.g., invalid token), authentication requirements, or rate limits. Aspect is minimal but not misleading.

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?

Two sentences with no redundancy. First sentence communicates core purpose, second adds valuable context about legacy replacement and feature support. Efficient and well-structured.

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 simple get tool with two well-described parameters and no output schema, the description covers the essential purpose and legacy context. It could mention that it is read-only or prerequisites, but overall is sufficiently complete.

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 coverage is 100% with descriptions for both parameters. The description adds context about purchase options and offers but does not elaborate on parameter semantics beyond what the schema already provides. Baseline score of 3 is appropriate.

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 verb 'Get current state' and specifies the resource 'one-time product purchase'. It distinguishes from siblings by mentioning support for multiple purchase options and offers, and notes it replaces a legacy tool, making its scope precise.

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 for retrieving purchase state but lacks explicit when-to-use or alternatives. It mentions it replaces legacy but does not elaborate on scenarios where sibling tools like onetime_products_get or purchases_subscriptions_v2_get might be more appropriate.

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