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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds the store/date scoping constraint but says nothing about result volume or pagination, which matters here since replies can be truncated server-side.

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?

Two front-loaded sentences: behavior first, endpoint path second. No filler and nothing repeated beyond what is needed for orientation.

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?

Adequate for a read-only list tool with a rich 7-parameter schema, but with no output schema the description could usefully hint at what a page of closed sales contains or reinforce the limit/offset continuation pattern for large months.

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%, so all seven parameters including day, page, offset and limit are already documented in the schema. The description restates the day semantics but adds no syntax or format detail beyond what the schema provides.

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 ('List the closed (completed) sales of a store') and scopes it to one day or one month. The 'closed (completed)' qualifier implicitly separates it from the sibling hiboutik_list_open_sales, though that sibling is never named.

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 explains the day-omitted case rolls up to a full month, which is useful usage context. However, it never states when to prefer this over hiboutik_list_open_sales, hiboutik_get_sale, or hiboutik_report_turnover, leaving sibling routing to inference.

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