Feature & Specification Comparison

Specification	Sysknife lacs-project Command Line	Fauxnix 20000419 Command Line
Summary	Security-hardened MCP server for Linux system administration via 189 typed actions instead of shell strings, with an Ed25519-signed hash-chain audit log, one-time TTL approval receipts, and automatic rollback. Works with Claude Code, Cursor, and Codex CLI.	bash for AI agents on Windows via deterministic bash→PowerShell translation — no WSL, VM, or bash toolchain. MCP bash tool with GNU-style output, bash-style errors, coreutils exit codes, session-persisted cwd/env across calls, and per-file UTF-8/GBK sniffing (GBK files grep correctly, unlike Git Bash). Unsupported bash constructs fail loudly with the construct named; native commands (git/node/npm) pass through with argv quoting. npm install -g fauxnix-cli; verified with Claude Code, Codex, OpenCode, Kimi Code and Qwen Code.
