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

With no annotations provided, the description carries the full behavioral disclosure burden. It discloses that the call is free and payment-free, returns the entire catalog, includes prices in USD, and notes language availability and practitioner verification. It does not mention side effects or pagination, but for a zero-parameter catalog read, the key behavioral aspects are covered.

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 dense but well-organized, front-loading the most important fact (FREE, no payment required) and the primary use case. Each sentence adds useful context: what is returned, how items are identified, content quality, languages, and the no-parameters note. Minor redundancy between 'FREE' and 'no payment required' prevents a perfect score.

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?

The description is complete for a zero-parameter listing tool with no output schema. It tells an agent exactly what to expect: every catalog item, the id and price fields, the tool needed to retrieve each item, the content categories, languages, and reviewer credentials. An agent has enough information to call this tool and use its results to route subsequent calls correctly.

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 tool has zero parameters and the input schema is empty, so there are no parameter semantics to clarify. The description explicitly states 'Takes no parameters,' which reinforces the schema and prevents an agent from inventing arguments. This meets the baseline for parameter-free tools.

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 identifies a specific verb-resource pair: browse the full MotherWise catalog. It differentiates itself from the sibling retrieval tools by stating it returns every available item with ids, prices, and the exact tool needed to retrieve each item. This leaves no ambiguity about what the tool does.

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 says to call this tool first before making any paid call and to discover valid ids, affirmation stages, and week values for other tools. It does not name sibling tools explicitly, but it clearly frames this as the discovery entry point, which is strong usage guidance. A slight deduction because it does not explicitly state when not to use it.

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