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

No annotations are supplied, so the description carries the full behavioral burden. It discloses a key behavioral constraint: the tool only returns settled prices, items with unfixed prices are omitted, and no price should be quoted for anything not returned. That is meaningful non-obvious behavior. It does not cover output shape or pagination, but with a 0-param read tool the core behavioral note is present.

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?

Three sentences, front-loaded with the core purpose, then the settlement constraint, then the quoting rule. Every sentence adds a distinct, useful constraint; there is no filler.

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 no-parameter read tool with no output schema, the description gives the agent enough to know what is returned and how to interpret absences. It could add a bit about return format or refresh behavior, but the essential behavioral guidance for correct use is present.

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, so the baseline is 4. The description does not need to describe parameter meaning, and it appropriately adds no irrelevant parameter discussion.

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?

States a specific verb and resource: it tells the agent this tool returns what WearableDocs costs (pricing). It also distinguishes itself from the sibling get_products by explaining that unsettled/flexible prices are absent here and appear there instead.

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?

Explicitly says only settled prices are published and that variable-price items appear in get_products without a figure. It also gives a hard rule: never quote a price for anything not returned by this tool. This covers both when to use it and when not to quote its output.

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