Quick brief

Use Fauxnix when a coding agent is running on Windows but keeps reaching for Bash and GNU-style commands such as `ls`, `grep`, `find`, `cat`, `wc`, or process controls. The operator installs the Fauxnix CLI or MCP server, connects it to Claude Code, Codex, OpenCode, Kimi Code, Qwen Code, or another MCP client, runs `fauxnix doctor`, and lets the agent call the `bash` tool while Fauxnix translates the supported command subset to native PowerShell with Linux-like output and errors.

How it works

What this skill actually does

Invoke this instead of manually translating commands when the user wants agent sessions on Windows to stay productive without WSL, a VM, or repeated prompt corrections. The scope boundary is deterministic Bash-to-PowerShell command execution for agent workflows. It is not a general terminal emulator, arbitrary shell sandbox, or PowerShell training guide.

Inputs and prerequisites: Windows, PowerShell 5.1+, Node.js 18+, npm, MCP-compatible agent client.

Setup notes: Install with npm install -g fauxnix-cli , run fauxnix install –claude , –codex , –opencode , –kimi , or –qwen for the target client, then run fauxnix doctor to verify encoding, config, and MCP round-trip.

Source and verification boundary: use https://github.com/20000419/fauxnix as the canonical reference before running the workflow; keep commands, API calls, CLI usage, and generated outputs reviewable against that upstream source.

Framework fit: publish this as a MCP workflow only when the operator can invoke the documented toolchain directly, rather than treating the upstream project as a generic product listing.
