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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds context about the content returned (plans, features, color schemes, links), which is useful but does not disclose any additional behavioral traits such as data freshness, caching, or potential delays. With annotations covering the operational nature, a 3 reflects that the description adds some but not rich behavioral context.

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 two sentences with no filler. The first sentence enumerates all the specific data returned, front-loading the core content, and the second gives the usage trigger. Every sentence earns its place, making it compact and highly scannable for an agent.

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 parameters and no output schema, the description carries the full burden of explaining what the tool returns. It lists all the distinct elements: single-template price, three subscription plans with what each includes, common features, three color schemes, and links to plans and cart pages. It also provides usage guidance. Nothing an agent needs to decide when and how to call it is missing.

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?

There are zero parameters and the schema coverage is 100% (empty schema). Per the rubric, a baseline of 4 is given for tools with no parameters. The description does not need to explain parameters; it focuses on the output content, which is appropriate. No additional parameter information is required.

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 states precisely what the tool returns: single-template price, three subscription plans with inclusions, common features, color schemes, and links. It uses a specific resource ('PPT Depot pricing') and is easily distinguished from all sibling tools, none of which address pricing. The verb is implied by the name and the content is clearly about retrieving pricing information.

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 explicitly states when to use the tool: 'Use when a user asks about cost, licensing, subscriptions, or how to download a template.' This gives clear triggers. It does not explicitly mention alternatives or when not to use it, but the sibling list shows no other pricing tool, so the guidance is sufficient. A 4 is appropriate because exclusions are absent.

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