Overview

Compare two decimals under an explicit absolute, relative, or basis-point tolerance. The skill uses exact decimal arithmetic, reports the resolved policy, rejects unknown properties, and never fetches a rate or infers accounting policy.

Money arithmetic needs explicit currency, scale, tolerance, and rounding semantics; an LLM cannot guarantee those constraints or reproduce residuals.

Reliability

STRICT and stateless. AMOUNT_INVALID means a malformed or over-limit decimal; fix it. CURRENCY_UNKNOWN means the code is outside the documented allowlist; send a supported code. CURRENCY_MISMATCH is triggered when one sum contains different currency codes; retry only after converting first or splitting the rows by currency. TOLERANCE_INVALID means a negative or unsupported tolerance; correct its type and value. ROUNDING_INVALID means mode or scale is unsupported; choose a documented value. ITEM_LIMIT_EXCEEDED means more than 10,000 rows; split them.

Context footprint

One call returns normalized money strings and the resolved policy. A successful call costs 1 execution credit.

When to use it

When you judge two amounts on the same unit basis inside an explicit absolute, relative, or basis-point band.

When the amounts are in different currencies, or the tolerance type has not been chosen.

Scope

Note

Compare two decimals under an explicit absolute, relative, or basis-point tolerance

Non-goals

Does not fetch FX rates or convert currencies
Does not infer materiality, accounting policy, cash rounding, or locale

Input schema

Field	Type	Required	Description
left	string	Yes	Required plain decimal on the same unit basis as right.
right	string	Yes	Required plain decimal on the same unit basis as left.
toleranceType	string	Yes	Required absolute, relative, or basis_points.
tolerance	string	Yes	Required non-negative plain decimal; relative is a ratio and basis_points is divided by 10,000.
referenceSide	string	No	Optional left, right, or max absolute value; omitted means max. Ignored for absolute tolerance.

Output schema

Field	Type	Required	Description
withinTolerance	boolean	Yes	Whether absolute difference is at most the resolved limit.
difference	string	Yes	Absolute left-right difference.
limit	string	Yes	Resolved absolute comparison limit.
toleranceType	string	Yes	Applied tolerance type.
referenceSide	string	Yes	Resolved reference side.
