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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the tool is clearly a safe read operation. The description adds that it filters by date and status, which matches parameters, but does not disclose other behavioral details such as pagination, ordering, or limits. With annotations covering safety, this is adequate but minimal.

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 a single sentence that is concise and front-loaded with the primary purpose. It avoids unnecessary words but could benefit from slight expansion to cover parameters without losing conciseness.

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 tool has 5 optional parameters and no output schema, yet the description is sparse. It does not explain return values, pagination, or constraints on date formats. Given the lack of schema descriptions, more detail is needed for complete understanding.

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 0%, so the description must compensate. It mentions filters by 'date' and 'status,' but does not explain all parameters (account, category are omitted). 'Status' is ambiguously mapped to the 'paid' boolean. The description adds some meaning but leaves significant gaps.

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 states the verb 'List' and the resource 'financial transactions,' specifying scope as 'payments, receivables' and filters by date and status. It distinguishes from sibling tools, as no other dietbox tool lists transactions. However, 'status' is not explicitly defined; only a 'paid' boolean parameter is present, causing slight ambiguity.

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 provides no guidance on when to use this tool versus alternatives. While there is no direct sibling competitor for listing transactions, it does not mention related tools like dietbox_list_accounts for account-level queries. Usage context is entirely inferred from the name and purpose.

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