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

Beyond the idempotent and non-destructive annotations, the description adds the useful behavioral fact that processing happens locally in the browser, implying no server-side data transfer. This contextualizes the tool's execution model without contradicting the annotations.

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 core purpose is front-loaded and compact, but the description includes a redundant title prefix, a double-period typo, and a canonical URL that provides little value for tool selection or invocation. It is concise overall, but not every element earns its place.

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 an output schema present and all three parameters documented with sensible defaults, the description covers the main decision points: what the tool compares and that processing is local. An agent has enough information to invoke it correctly for a simple debt-payoff comparison.

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?

The input schema already provides 100% coverage with clear descriptions for balance, interestRate, and monthlyPayment. The tool description does not add parameter-specific detail beyond the comparison use case, so it stays at the baseline for fully documented schemas.

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 ('Compare') and clearly identifies the resource: avalanche and snowball debt payoff strategies with interest savings. This makes the tool's function unmistakable and distinguishes it from sibling calculators like mortgage amortization or retirement planning.

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?

Usage is implied by the description: an agent can infer this tool is for comparing debt payoff strategies. However, it does not explicitly state when to use it versus other financial calculators, nor does it name alternatives or exclusions.

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