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

Annotations already declare readOnlyHint=true and idempotentHint=true, establishing safety. The description adds the price ('$2.00 USDC via x402') and content structure ('four-part'), which are useful beyond annotations. However, it doesn't disclose whether the worksheet is returned directly or how the payment affects the interaction, so it's adequate but not rich.

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 extremely brief with two sentences and no filler. The first sentence states the resource type, and the second provides pricing. However, it may be too short to be genuinely useful, but by conciseness and structure standards it is well-organized and front-loaded.

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?

Given the absence of an output schema and only one parameter, the description should clarify what the tool returns and how to use it. It does not mention return values, topic semantics, or how the price is applied. The description is incomplete for an agent to safely invoke the tool, even though annotations cover the read-only aspect.

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 0%, and the description doesn't mention the required 'topic' parameter at all. With one required parameter and no explanation of its meaning or format, the agent cannot infer how to fill it. The description entirely fails to compensate for the schema's lack of documentation.

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 only states 'A reusable four-part weekly planning worksheet.' It lacks an explicit verb indicating what the tool does (e.g., provides, creates, returns). This is close to a tautology with the title '20-Minute Weekly Reset' and does not clearly differentiate from sibling store-* tools.

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 no guidance on when to use this tool versus alternatives. It doesn't mention use cases, prerequisites, or relationships to sibling tools like store-operations-bundle or store-client-kickoff, leaving the agent without context for selection.

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