delete_expense_attachment

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

The description explicitly labels the action as 'irreversible' and requires user confirmation. The annotation destructiveHint: true is present, and the description adds the need for user confirmation, which is beyond the annotation.

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, front-loaded sentence with a warning icon, conveying all essential information without unnecessary words.

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 description covers the action, irreversibility, and user confirmation, but lacks parameter details. With an output schema present, return values are not needed, but the parameter gap reduces completeness for a simple tool.

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% (no description for expense_id), and the description does not explain the parameter. It only appears in the schema without any added meaning, which fails to help the agent understand the input.

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 action 'elimina el adjunto de un gasto' (delete expense attachment), using a specific verb and resource. This distinguishes it from siblings like delete_expense (delete whole expense) and delete_income_attachment.

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 includes 'Confirmar con usuario' (confirm with user), indicating when to use this tool (only after user confirmation). It does not explicitly list alternatives, but the sibling names and context make the distinction clear.

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