dsh-math

Scientific computing plugin for DeepSeek Harness. It registers a single math tool that covers both numeric computation and symbolic algebra (CAS), so an agent can evaluate expressions and derive/simplify formulas without leaving the conversation.

Features

The math tool takes an operation, an expression, and an optional variable.

operation	description	engine
eval	numeric expression: units, matrices, statistics, complex numbers, big numbers	mathjs
simplify	simplify an expression	Algebrite
expand	expand an expression	Algebrite
factor	factor a polynomial	Algebrite
derivative	differentiate with respect to a variable	Algebrite
integral	symbolic indefinite integral	Algebrite
solve	find the roots of a polynomial	Algebrite

Two engines share the work: mathjs handles numeric evaluation (units, matrices, statistics, complex numbers, big numbers), and Algebrite handles symbolic algebra (integration, factoring, and equation solving that mathjs does not provide).

Install

From npm:

dsh plugin --profile web add dsh-math

From a git host (requires the repository's prepare script to build, or pin a commit):

dsh plugin --profile web add github:owner/dsh-math

Usage

The agent calls the math tool automatically when it needs a computation. Examples of what it can answer:

• determinant: det([[1,2],[3,4]]) → -2
• unit conversion: 5 cm to inch → 1.9685039370078743 inch
• big number: 2^100 → 1.2676506002282294e+30
• derivative: derivative(x^2, x) → 2*x
• integral: integral(x^2, x) → 1/3*x^3
• solve: roots(x^2 - 3x + 2) → [1,2]
