Progressive Income Tax Estimator

tax_estimate

Estimate income tax using progressive brackets. Supports custom brackets for any country or year, providing total tax, after-tax income, per-bracket breakdown, and effective vs marginal rate.

Instructions

Estimate income tax under a progressive bracket schedule. Defaults to US 2024 single-filer federal brackets but accepts any custom brackets (any country/year). Reports total tax, after-tax income, the per-bracket breakdown, and your effective vs marginal rate.

Tool call template

TDQS

A4.3/5.0
Behavior4/5

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

No annotations provided, so description bears full burden. It discloses default behavior (US 2024 single-filer) and customizability, plus outputs (total tax, after-tax income, breakdown, rates). It does not mention side effects or requirements, but as a calculator, this is adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three well-structured sentences with no redundancy. Purpose is front-loaded, and every sentence adds essential information. Highly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple calculator with 3 parameters and no output schema, the description explains inputs (including defaults and custom brackets) and outputs (total tax, breakdown, rates). It is complete and self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds value by explaining default bracket usage and customizability, and it notes the deduction parameter (though not by name). It provides context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it estimates income tax under a progressive bracket schedule, specifying default US brackets and customizability. It is distinct from sibling financial tools like budget_analyzer or loan_amortization.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for tax estimation but does not explicitly state when to use versus alternatives or provide exclusions. It lacks explicit guidance on when to choose this tool over others.

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