debt_payoff__interest_savings

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

No annotations are present, and the description provides no information about side effects, required permissions, rate limits, or behavior. The tool's purpose and consequences are entirely opaque.

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 at the cost of missing all necessary information. This is under-specification, not conciseness. A useful description would add context in a few sentences.

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?

With no schema descriptions, no output schema, and a one-phrase description, the tool is severely incomplete. It fails to explain inputs, outputs, or purpose, making it nearly unusable for an AI agent.

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 parameters (debts array, monthly_budget number). The agent has no context on what constitutes 'debts' or how 'monthly_budget' is used.

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 a tautology: '[debt-payoff] interest_savings' simply repeats the tool name. It does not state what the tool does or differentiate it from siblings like avalanche_schedule or snowball_schedule.

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 guidance is provided on when to use this tool versus alternatives. The sibling list includes several debt_payoff tools, but the description offers no criteria for choosing interest_savings over them.

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