dsh-mobius

The Mobius function shows up repeatedly in number theory, combinatorics, and algorithmic work, yet many projects end up pulling in heavy math libraries or external services just to evaluate it. dsh-mobius strips the problem down to its lightest form: a pure Node.js implementation with zero network dependencies. Once installed, its registered tool is available in-session with no authentication, proxy, or endpoint to configure.

The core capability is straightforward — wrapping the Mobius function's evaluation as a ready-to-use session tool. Because nothing is fetched over the wire, it behaves consistently in offline environments, sandboxes, and local scripts, with a short and predictable call path. The implementation stays lean and free of extra abstractions, so you can read or adapt it easily when needed.

It fits well when you want to verify a Mobius value quickly inside a session, run batch number-theoretic calculations in local or automated pipelines, or simply avoid adding an entire dependency tree for a single mathematical helper. If you are already in a dsh workflow and only need the occasional evaluation, this plugin is the lowest-friction option available.
