[Kernel Feature] /dev/llm Virtual Device - FUSE-Based LLM Interface

[mikejmorgan-ai]

/dev/llm Virtual Device Interface - FUSE-Based LLM Access

Part of: Kernel-Level AI Enhancements (Tier 1 - User-Space)

Description

FUSE-based virtual device providing file-like interface to LLM operations. Enables shell scripts and any Unix program to use LLMs.

Effort: 2-3 weeks | Bounty: $125

The Solution

# Mount the device
cortex-llm-device mount /mnt/llm

# It is just files!
echo "What is 2+2?" > /mnt/llm/claude/prompt
cat /mnt/llm/claude/response

# Works with any Unix tool
git diff | (echo "Review: $(cat)" > /mnt/llm/claude/prompt && cat /mnt/llm/claude/response)

# Session management
mkdir /mnt/llm/sessions/my-project
echo "Hello" > /mnt/llm/sessions/my-project/prompt
cat /mnt/llm/sessions/my-project/history  # Full conversation

Features

• FUSE filesystem implementation
• Multiple model endpoints
• Session management via directories
• Configuration via JSON files
• Mock client for testing without API key
• Anthropic API integration

Acceptance Criteria

• Filesystem mounts successfully
• echo/cat workflow produces valid responses
• Sessions maintain conversation context
• Configuration changes take effect
• Works with mock client (no API key)

Files

Complete implementation available:

• llm_device.py (~600 lines)
• test_llm_device.py (~300 lines)
• README_DEV_LLM.md

Priority

Medium - Innovative UX, demonstrates kernel-level thinking

Hi, I'm interested in taking this bounty.

Relevant experience:

• Anthropic Claude API integration (built production autonomous systems)
• Python FUSE filesystems (fusepy)
• Unix systems programming and IPC

Approach:

• Week 1: Core FUSE implementation + Claude API integration with mock fallback
• Week 2: Session management, configuration, testing

Can start immediately. Estimated completion: 2 weeks.

Happy to discuss the approach or share more details about my experience.

Update: Prototype Complete

I've built a working implementation with all acceptance criteria met:

Test Results: 20/20 passing

TestMockClient (3 tests) ✓
TestSession (3 tests) ✓
TestLLMDevice (9 tests) ✓
TestSessionFiles (5 tests) ✓

Implementation:

• llm_device.py (~500 lines) - Full FUSE filesystem via fusepy
• Mock + Claude API client
• Session management with conversation history
• JSON config files
• Metrics tracking

Demo:

# Mount
python llm_device.py mount /mnt/llm

# Use
echo "What is 2+2?" > /mnt/llm/claude/prompt
cat /mnt/llm/claude/response  # Returns: 4

# Sessions
mkdir /mnt/llm/sessions/my-project
echo "Hello" > /mnt/llm/sessions/my-project/prompt
cat /mnt/llm/sessions/my-project/history

Ready to submit PR whenever you'd like to review.

Actually — just saw your FUSE experience. Issue #223 (/dev/llm virtual device) is a perfect match:

#223

This is exactly your wheelhouse:

• Python FUSE filesystem
• Claude API integration
• Unix file interface to LLMs

$125 bounty, 2-3 weeks.

take both if you're up for it ($225 total).

[yaya1738]

I'll take this one too! The FUSE implementation is ready with 20/20 tests passing.

Will submit PR alongside #222. Both implementations are complete and tested.
