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

The annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds a meaningful authorization requirement ('Needs an owner or admin') and clarifies that the id comes from list_budgets.

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 two short sentences with no wasted language. The core action and id source are front-loaded, followed by the authorization requirement.

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 one-parameter delete tool with rich annotations and an output schema, the description covers what an agent needs: the action, the identifier source, and the permission requirement. Return values need not be explained because an output schema exists.

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%, and the sole parameter budget_id is only typed as an integer in the schema. The description compensates by explaining that budget_id is the id obtained from list_budgets, giving the parameter clear semantic grounding.

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: deletes a budget, identified by its id from list_budgets. It is clear and actionable, but it does not explicitly distinguish this operation from the related set_budget sibling.

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?

It gives a useful prerequisite ('Needs an owner or admin') and indicates where to obtain the id ('from list_budgets'), which implies when to use it. However, it does not explicitly state when not to use it or name alternatives such as set_budget for creating or updating budgets.

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