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

No annotations are provided, so the description carries the full behavioral burden. 'Get' plus 'current price, availability' usefully signals a read-only, point-in-time snapshot, but it says nothing about error behavior for an invalid or stale product_id, currency/locale of prices, or rate limits.

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?

One sentence, front-loaded with the verb and resource, with the returned fields and the ID provenance packed in without waste. Nothing is repeated or padded.

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 single-parameter read tool with no output schema, the description is sufficient: it explains where the ID comes from and what fields the result contains. The main remaining gap is failure/edge-case behavior for a bad ID, which is minor at this complexity.

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% and the single parameter already carries the same example ID, so the schema does the documentation work. The description adds the provenance hint (the ID comes from search_products), which is mild added meaning but nothing about format constraints.

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 (Get) and resource (one Men Groomer product by product_id) and enumerates what comes back: current price, availability, and full description. The 'one ... by its product_id' phrasing clearly separates it from search_products, which returns multiple results.

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 names the sibling that supplies its input ('from search_products, e.g. K382-19120'), which implicitly routes the agent: search first, then fetch detail by ID. It doesn't state explicit exclusions or when-not-to-use (e.g. don't call for browsing/listing), so it stops short of a 5.

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