delete_invoice

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

Annotations already mark it as destructive. The description adds 'irreversible' and a user confirmation requirement, providing useful behavioral context beyond annotations.

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 extremely concise, using two short sentences to convey purpose, irreversibility, and the need for user confirmation. No 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 purpose and user confirmation, but lacks information about output or error handling. Given the tool's simplicity and the presence of an output schema, some additional context would be beneficial.

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?

With 0% schema description coverage, the description adds no meaning for the invoice_id parameter. The sole parameter is implied by the tool name, but the description does not clarify its format or required nature.

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 tool deletes an invoice and is irreversible, which matches the name and distinguishes it from other invoice-related tools like void_invoice.

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 instructs to confirm with user, providing a usage hint, but does not specify when not to use this tool or mention alternatives like void_invoice.

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