- Concurrent File Edits and Reads: Enabled simultaneous editing and reading of multiple files, improving efficiency for large codebases.
- Prompt History Navigation: Allowed users to cycle through prompt history using up and down arrow keys when the cursor is at the start of the input.
Rue Code 3.21
- Official Marketplace Launch: The marketplace for MCPs and modes became officially available to all users.
- Direct Claude Max Support: Integrated direct support for Claude Max subscriptions, allowing users to access Sonnet 4, Opus 4, and other models without API keys.
- Excel and LaTeX Support: Improved Excel file support and enabled rendering of LaTeX equations in the chat.
Rue Code 3.22
- Timer-Based Auto Approval: Introduced timer-based auto-approval for follow-up questions, reducing manual intervention.
Rue Code 3.23
- Stable Codebase Indexing: Codebase indexing graduated to a stable feature, running in the background to maintain an up-to-date semantic understanding of the project.
- Task To-Do List: Introduced a new task to-do list feature, displaying a checklist of steps for a task directly in the chat.
- Command Deny List: Added a command deny list to automatically reject unwanted commands in workflows.
- Rue Code Cloud Waitlist: Made the Rue Code Cloud waitlist signup available on the website and in the extension.
- Claude Code Provider - Windows Support: Added native Windows support for the Claude Code provider.
- Smarter Command Validation: Improved command validation logic to only auto-deny subshell commands with denied prefixes.
Rue Code 3.24
- Hugging Face Provider: Integrated Hugging Face as a provider, allowing access to thousands of open-source models.
- Agent Rule Standard: Introduced the agent rule standard with agents.md files, enabling the sharing of natural language guidelines across Rue Code and other compatible tools.
- Interactive Terminal Command Permissions UI: Added a new interactive UI for managing command patterns visually, with intelligent pattern suggestions and quick toggles.
Rue Code 3.25
- Custom Slash Commands: Introduced custom slash commands, allowing users to automate workflows by placing markdown files in the RU commands folder. A management UI was added for creating, editing, and deleting commands, with argument hints and rich descriptions for self-documenting commands.
- Message Queuing: Added message queuing, allowing users to type and send messages while Rue is still processing earlier ones.
- New Model Providers: Added Cerebras, Dubao, Sambanova, and new shoots AI models.
- Rue Code Cloud: Introduced Rue Code Cloud, extending the Rue Code extension with cloud-powered features for enhanced collaboration, data persistence, and usage tracking.
Marketplace Demonstration
- Accessing the Marketplace: Click the marketplace icon in the top bar to access the catalog of available MCPs and modes.
- Installation Process: Select an MCP or mode, choose whether to install it for the current project or globally, and enter any required configuration details (e.g., API keys).
- Seamless Integration: Installed MCPs and modes are immediately active without requiring config file modifications or extension restarts.
Codebase Indexing Details
- Semantic Embeddings: Rue Code analyzes the entire project and generates semantic embeddings for all files.
- Vector Indexing: The AI queries the vector index to retrieve the most relevant files and context when searching or making changes.
- Performance Improvement: Codebase indexing improves search speed, accuracy, and the quality of code suggestions and refactors, even in large repositories.
Task To-Do List Functionality
- Automated Checklist Generation: Rue Code can automatically break down new tasks into a checklist of steps, displayed in the chat window.
- Progress Tracking: The AI checks off each step as it is completed, providing real-time progress tracking.
- Model-Specific Configuration: To-do lists can be enabled or disabled per model in the advanced settings.
Custom Slash Commands Explained
- Markdown-Based Commands: Custom commands are created using simple markdown files.
- Command Manager: The command manager generates a starter file for new commands.
- Argument Hints: Argument hints are displayed as visual placeholders in the chat, making it easy to remember the required inputs.
- Workflow Automation: Custom commands can turn multi-step workflows into single actions, improving productivity and standardizing best practices.
Concurrent File Processing
- Multi-File Operations: Rue Code can edit or read multiple files simultaneously, saving time when making sweeping changes or gathering information from multiple sources.
- Model Compatibility: Concurrent file processing works especially well with models like Opus 4 and Gemini 2.5.
Image Support with OCR
- Text Extraction: Rue Code can extract text from images using OCR, allowing users to process documentation, receipts, and other visual data.
Rue Code Cloud Features
- Accessing Rue Code Cloud: Sign into Rue Code Cloud via the icon in the extension.
- Usage Dashboard: View the usage dashboard to see the history of tasks, models used, and other relevant information.
- Collaboration: Share tasks with others and generate public share links from the Rue Code extension.
Free APIs and Model Access
- Horizon Beta Model: A free, fast, and unlimited model.
- Quen 3 Coder: Free API available via Open Router and Cerebras.
- Cerebras Code Plans: Paid plans ($50 and $200) offering almost unlimited access to the Quen three coder API with 2,000 tokens per second speed.
- Kilo Code: A fork of Root Code with $20 of free credits for using any model.
