set_budget

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

With no annotations provided, the description must carry the full behavioral disclosure burden. It only states the basic action and does not explain whether an existing budget is overwritten, whether the limit must be positive, whether the operation is idempotent, or what side effects occur.

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 no filler. Every word contributes to the core meaning, and it is appropriately sized for a simple two-parameter tool.

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?

Given that the input schema is minimal (0% coverage, no enums) and no annotations are present, the description is too thin to fully support an agent. It lacks behavioral details, parameter constraints, and any guidance on existing budgets, making it incomplete for a mutating 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 description coverage is 0%, so the description must compensate. It adds the currency context 'PKR' and the notion of a monthly limit, but it does not explain valid category values, restrictions on monthly_limit, or the relationship between the two parameters beyond their obvious titles.

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 uses a specific verb ('Set') and resource ('monthly spending limit') with a clear currency and context ('PKR', 'for a category'). It clearly distinguishes itself from sibling tools like budget_status, which would check the budget rather than set it.

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?

No explicit guidance is given about when to use this tool versus alternatives such as budget_status or update_expense. The usage is only implied by the verb 'Set' and the resource, but there are no stated conditions, exclusions, or alternative routing.

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