Managing files, running automation tasks, and orchestrating terminal commands with local LLMs can be challenging, especially when running across multiple operating systems.
Today, I am releasing SamarthyaBot v2.3.0 to npm and GitHub. This release transforms SamarthyaBot from a Linux-centric utility into a cross-platform local Agentic AI Operating System.
Here is a technical walkthrough of how we resolved cross-platform challenges, sandboxed execution, and added native capabilities.
1. Achieving OS Portability (Linux, macOS, Windows)
Previously, SamarthyaBot relied on Unix-style paths, shell utilities, and a pre-compiled Go worker binary specifically built for Linux.
To achieve true cross-platform compatibility, we introduced a centralized Platform Service (backend/services/system/platform.js):
- Dynamic Shell Discovery: Resolves execution contexts between Windows (cmd.exe or powershell.exe) and Unix platforms (/bin/sh or /bin/bash).
- Process Fallback: If the Go binary is not compiled for the host OS, the runtime falls back to a native Node executor (workerClient.js). This ensures streaming executors run reliably without crashes.
- Context Injected Prompts: The host OS type is supplied directly to the LLM system prompt. The LLM adjusts its code generation to match the OS constraints (e.g., using dir on Windows and ls on Unix).
2. Hardening the Sandbox & Preventing Command Injection
Allowing an AI agent to run shell commands and read/write files presents significant security challenges. In v2.3.0, we introduced multi-layered boundaries:
A. Spawning over Shell Interpretation
We removed raw shell string execution from utility tools such as open_path. Instead of running:
// Vulnerable to target = "file.txt; rm -rf /"
exec(`open "${target}"`);
We now spawn processes with clean argument arrays and reject shell metacharacters:
// Secure approach
spawn(opener, [target], { shell: false });
B. Segment Validation for Chained Commands
Users or models might try chaining commands using &&, ;, |, or \r. The command validation engine now splits inputs by these delimiters and inspects each segment against a blacklist (blocking unauthorized sudo, fork-bombs, and destructive commands).
C. Workspace-Scoped Sandbox
All file system tools are constrained to the current project workspace by default. Boundary checks ensure the agent cannot use directory traversal (../../) or absolute path patterns to escape the designated workspace.
3. Expanding the Agent Skillset (34 Skills)
We added 10 new functional tools to give the agent more capabilities out of the box:
- Utilities: password_generate, qr_generate, url_shorten, ip_geolocate, timezone_now.
- Automation: clipboard_copy, translate_text (with dedicated Hindi capabilities), open_path, and http_request (with SSRF guard blocking standard and local schemes like file://).
- Security & Math: hash_text, base64_tool, currency_convert, crypto_price.
4. Zero-Latency Slash Commands
To keep the agent responsive, slash commands such as /help, /status, /tools, and /memory are processed instantly at the controller level without calling the LLM. This cuts down token usage and latency to zero for routine status checks across Web, Telegram, and Discord channels.
5. UI/UX Refresh
The web dashboard is updated with modern design aesthetics:
- Tricolor aurora animated background gradient.
- Subtle grid-pattern background.
- Glassmorphism panels with top-border highlights.
- Dynamic hover actions, sheen sweep buttons, and responsive scale transitions.
Getting Started
You can self-host SamarthyaBot locally with your choice of LLMs (Gemini, Claude, GPT, Ollama, DeepSeek, or Qwen).
