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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful behavioral context by specifying that revenue is aggregated by transaction date and mapping to 'Accounting.NetRevenue', but it does not explain return units, currency, or aggregation behavior.

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 compact and front-loads the resource and scope in a single sentence. The trailing 'Accounting.NetRevenue' reference is slightly opaque but does not waste much space.

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 simple read-only tool with fully documented parameters, the description covers the essential purpose and date semantics. However, because no output schema exists, it leaves the return format, currency, and aggregation details unstated, which are relevant for interpreting a net revenue result.

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 coverage is 100%, so all three parameters are already documented. The description adds meaning beyond the schema by clarifying that the date range filters by transaction date rather than another accounting date, which is useful for correct invocation.

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 names a specific resource ('net revenue/turnover'), scopes it to 'an administration' and 'a date range', and clarifies the date basis ('by transaction date'). It is clearly a retrieval operation, though it does not explicitly distinguish itself from sibling reporting tools such as yuki_get_gl_account_balance.

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?

There is no explicit guidance on when to use this tool versus alternatives, nor any stated preconditions or exclusions. Usage is only implied by the resource name and date-range mention.

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