personal_budgeting__fifty_thirty_twenty

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

No annotations are provided, so the description carries the full burden. It merely repeats the name and offers no behavioral details such as what the tool computes, side effects, or required permissions. It fails to disclose any behavioral traits.

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 short but not concise in a helpful way; it is under-specified. It wastes the opportunity to convey purpose or context.

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 the tool has one parameter and many sibling tools in personal budgeting, the description is completely inadequate. It does not help the agent understand what the tool does, how to invoke it, or what output to expect.

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 description adds no meaning to the single parameter 'monthly_income'. The parameter is a number with no explanation of its role (e.g., expected format, currency, period).

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 is just a repetition of the tool name with a category prefix, e.g., '[personal-budgeting] fifty_thirty_twenty'. It does not state what the tool does, such as implementing the 50/30/20 budgeting rule, nor does it differentiate from sibling tools like savings_rate or zero_based_budget.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of context, prerequisites, or typical use cases.

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