rm_delete_expense_category

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

Annotations already signal destructiveHint=true and readOnlyHint=false, and the description adds the crucial behavioral detail that confirm=True is mandatory. It does not contradict the annotations, and the extra confirmation requirement adds value beyond the structured metadata.

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?

A single sentence with a parenthetical warning is perfectly sized. It front-loads the core action and adds the critical safety requirement without any filler.

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 two-parameter delete operation with a destructive annotation and an output schema, the description is nearly sufficient. It conveys the action, the danger, and the required confirmation flag. It only lacks a pointer to related listing tools or guidance on category_id provenance.

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 0%, so the description needed to compensate. It meaningfully explains the confirm parameter's role, which the schema alone implies only via default=false. However, category_id is left entirely to the schema and tool name, with no guidance on where to obtain it or what formats are valid.

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 states a specific verb and resource: 'Delete an expense category.' This clearly distinguishes it from sibling tools like rm_delete_expense, rm_delete_tag, and other delete operations. The destructive warning reinforces what the tool does.

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 gives clear and essential usage context: deletion is destructive and requires confirm=True. However, it does not explicitly state when to choose this tool over other delete siblings or mention any preconditions such as whether the category must have no associated expenses.

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