Beledarian's LM Studio Tools

This project is a plugin for LM Studio that provides a rich set of tools to a large language model. It acts as a bridge between the LLM and your local environment, enabling autonomous coding, research, and file management.

[!IMPORTANT] LM Studio does NOT support automatic updates. If you encounter issues, please try manually updating first by removing the current version and re-downloading from the plugin website. LM Studio may show an "already installed" tooltip, even if your version is outdated.

Key Features

File System Mastery

• Full Control: Create, read, update, delete, move, and copy files.
• Safe & Secure: All operations are sandboxed to your workspace directory to prevent path traversal attacks.
• Smart Updates: Use replace_text_in_file to make surgical edits instead of rewriting large files.
• Batch Processing: save_file supports creating multiple files in one go.
• Cleanup: Use delete_files_by_pattern to wipe temporary files instantly.

Recent Updates

• v1.1.1 Browser Reliability: Added robust click fallback handling for selectors like a.Link--primary when Puppeteer reports non-clickable nodes.
• v1.1.1 Navigation Context: browser_session_open now returns full page text by default for better multi-step planning.
• Gemma 4 Compatibility: Fixed sub-agent tool call parsing for models using parameters format (e.g., Gemma 4)
• Advanced Browser Navigation: Added persistent browser session tools with scripted actions, in-page fuzzy find, and URL-change notices
• Structured Sub-Agent Handoff: Added explicit handoff_message support for relaying findings/research

Autonomous Agents

• Secondary Agent: Delegate complex tasks (coding, summarization) to a second local model/server with support for the main model already used and loaded by LM Studio!
• Auto-Save: When the sub-agent generates code, the system automatically detects and saves it to your disk. No more copy-pasting!
• Auto-Debug: (Optional) Triggers a "Reviewer" agent to analyze generated code and fix bugs automatically before returning the result.
• Structured Handoff: Sub-agents can return a dedicated handoff_message for the main agent to relay findings/research.
• Project Context: Agents can read beledarian_info.md to understand your project's history.

Code Execution

• Sandboxed: Run JavaScript (Deno) and Python code.
• Terminal: Execute shell commands or open real terminal windows for interactive tasks.

[!WARNING] Enabling shell or terminal execution allows the model to run arbitrary commands on your system. If enabled, the model may be able to modify files and escape the sandbox environment.

Web & RAG

• Research: Search DuckDuckGo, Wikipedia, or fetch raw web content.
• Advanced Browser Navigation: Persistent browser_session_open/control/close flow for multi-step browsing and automation.
• Web RAG: Chat with website content.
• Local RAG: Semantic search over your workspace files (rag_local_files).

Requirements

• Node.js (v18+)
• LM Studio (v0.3.0+)

Installation

The plugin can be installed using the following link:

https://lmstudio.ai/beledarian/beledarians-lm-studio-tools

Alternatively, you can install it manually for development purposes.

Development

If you want to contribute to the development of this plugin, you can follow these steps:

• Clone the repository:

  git clone https://github.com/Beledarian/Beledarians_LM_Studio_Toolbox.git
  cd Beledarians_LM_Studio_Toolbox
  

• Install dependencies:

  npm install
  

• Run in development mode: From within the project directory, run the following command:

  lms dev
  

  This will start the plugin in development mode. LM Studio should automatically pick it up. Any changes you make to the source code will cause the plugin to automatically reload.

Configuration

Access these settings in the LM Studio "Plugins" tab:

• Enable Secondary Agent: Unlock the power of sub-agents.
• Sub-Agent Profiles: Custom prompts for "Coder", "Reviewer", etc.
• Auto-Debug Mode: Automatically review sub-agent code.
• Sub-Agent Debug Logging: Toggle detailed sub-agent parsing logs for troubleshooting.
• Sub-Agent Auto-Save: Toggle automatic file saving (Default: On).
• Show Full Code Output: Toggle whether to display the full code in chat or hide it for brevity (files are still saved).
• Default Workspace Path: Set the startup workspace directory used by the plugin.
• Safety: Enable/Disable "Allow Code Execution" for Python/JS/Shell.
• Browser Safety: Browser automation for sub-agents requires all three toggles: Allow Browser Control + Sub-Agent: Allow Web Search + Sub-Agent: Allow Browser Control.

Available Tools

File System

• list_directory, change_directory, make_directory
• read_file, save_file (supports batch), delete_path
• replace_text_in_file: Precision editing.
• delete_files_by_pattern: Regex-based cleanup.
• move_file, copy_file, find_files, get_file_metadata
• fuzzy_find_local_files: Levenshtein-based fuzzy file path/name search.

Agent

• consult_secondary_agent: The powerhouse tool. Delegates tasks, handles file creation, and manages sub-agent loops.

Web

• web_search (DuckDuckGo API + HTML fetch/browser fallback), wikipedia_search
• fetch_web_content, rag_web_content
• browser_session_open, browser_session_control, browser_session_close (persistent page automation; preferred for multi-step navigation, with deduped page-text output unless full_read=true)
• browser_open_page (stateless one-shot Puppeteer read)
• Workaround tip: if selector-based click fails, use an evaluate action to click by text, then call with full_read=true.

{
  "actions": [
    {
      "type": "evaluate",
      "script": "const link=[...document.querySelectorAll('a')].find(a=>a.textContent?.includes('LICENSE')); if(link) link.click();"
    }
  ],
  "full_read": true
}

Execution

• run_javascript, run_python
• execute_command (Background), run_in_terminal (Interactive)

Utils

• rag_local_files: Search your code.
• save_memory: Long-term memory.
• get_system_info, read_clipboard, write_clipboard
