context-llemur: A Context-Engineering CLI Tool

Efficiently manage and share context across various AI tools with ctx, the portable, version-controlled context-engineering command line interface. Gone are the days of repeating project details for every conversation with different Large Language Models (LLMs); ctx streamlines this process, enabling users to keep their context organized and accessible.

Key Features

• MCP Server Integration: Full support for Model Context Protocol (MCP), allowing seamless communication with AI agents.
• Git-Based Functionality: Leverage Git storage principles—no complex configurations or vendor lock-in—simple, powerful version control for context management.
• User-Friendly CLI: Designed for human interaction while providing flexibility and control.
• Cross-Compatible: Work effortlessly with any LLM without restrictions related to specific vendors.

Usage Highlights

Creating and Managing Contexts

The ctx tool facilitates context management through simple command-line operations.

# Create a new context repository (defaults to ./context)
ctx new

# Save project context for versioning
ctx save "Updated goals"

Advanced Features

The integrated MCP server allows users to:

• Explore Topics: Easily begin exploring new areas of interest by creating separate branches.
• Manage Repositories: Switch between contexts, track changes, and integrate insights back into the primary context.

ctx explore "new-topic"
ctx integrate "new-topic"

Features Overview

• Switch Contexts: Effortlessly navigate between multiple project contexts to maintain clarity and organization.
• Version Control: Track changes over time, allowing easy access to historical context and reverting to previous versions as needed.
• File Operations: Manage context files with commands for moving, renaming, and deleting files within the context repository.

Philosophy

ctx recognizes that the context of a project evolves naturally, incorporating elements like goals, rules, and milestones. Each context repository is tracked independently, promoting portability and easy sharing with both human and AI collaborators.

System Design

The design paradigm focuses on utilizing structured management instead of embedding retrieval, promoting clarity in project context management. Each context folder operates as a Git repository while providing a straightforward experience for LLM interaction.

Use Cases

ctx is particularly suited for use with agentic LLMs in various workflows, offering an organized, trackable way to communicate project context effectively. For instance, users can utilize ctx within Claude Desktop to manage fitness tracks or generate workout plans based on historical data.

With ctx, the complexities of context management for LLMs are simplified, leading to more productive and coherent conversations aligned with project goals.
