dsh-is-coprime

In number-theory proofs, modular-arithmetic feasibility checks, or RSA parameter validation, determining whether two integers are coprime is a frequent and foundational step. Traditionally you would sketch a quick gcd routine, run it, and read back the result, breaking your train of thought and opening the door to small off-by-one bugs. dsh-is-coprime collapses that step into a single in-session tool call so the AI assistant can return a coprimality verdict directly, eliminating the write-run-read loop.

The plugin is implemented in pure Node.js with zero external dependencies and zero network calls. Once installed, the tool is registered in the session context immediately. There is no server to boot, no environment variable to set, and no configuration file to maintain. This side-effect-free design means it can be dropped into any local inference pipeline without introducing supply-chain risk.

It is well suited to developers working in number theory and cryptography, to math-teaching sessions where coprimality checks appear mid-conversation, and to any team that wants its model-inference workflow to stay lightweight, deterministic, and fully offline-capable.
