list_subscription_price_points

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

With no annotations provided, the description carries the burden of behavioral disclosure. It implies a read-only operation but does not disclose additional traits such as pagination, permissions, or whether the list is exhaustive. The mention of optional territory filtering adds a behavioral nuance, but overall the description is minimal.

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 that communicates the core purpose and the optional filter in a concise manner. No words are wasted, and the information is immediately accessible.

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 listing tool with only two parameters and no output schema, the description provides sufficient context: it lists price points and shows that territory is an optional filter. It could be more complete by specifying the return format or any default behavior, but given the low complexity, it is adequate.

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 100%, so the input schema already fully explains both parameters. The description adds the phrase 'optionally filtered by territory', which is already captured by the optional property in the schema. Thus, the description adds little beyond what is already structured.

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 'List' and the resource 'available price points for a subscription', with an optional filter by territory. This distinguishes it from sibling tools like list_subscriptions or list_subscription_offers, which target different resources.

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 provides a clear context for when to use the tool (when listing price points for a subscription), but it does not explicitly mention alternatives or when not to use it. There is no reference to sibling tools or exclusions, so the guidance is implied rather than explicit.

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