Added custom Open WebUI function for SSH/SFTP file operations:
**New Function: save_to_disk.py**
- save_file(): Write generated code to local filesystem via SFTP
- read_file(): Read files from local disk
- list_files(): List directory contents
- Configurable via Valves (host, port, username, paths)
**Custom Dockerfile (Dockerfile.webui)**
- Based on ghcr.io/open-webui/open-webui:main
- Installs paramiko library for SSH/SFTP support
- Creates .ssh directory for key storage
**Configuration Updates**
- Mount SSH private key from host (/root/.ssh/id_rsa)
- Mount functions directory for custom tools
- Build custom image with SFTP capabilities
**Usage in Open WebUI**
Claude can now use these tools to:
- Generate code and save it directly to your local disk
- Read existing files for context
- List project directories
- Create new files in any project
Default base path: /home/valknar/Projects
Authentication: SSH key-based (passwordless)

Added LiteLLM as an OpenAI-compatible proxy for Anthropic's API to
enable Claude models in Open WebUI.
**New Service: litellm**
- Image: ghcr.io/berriai/litellm:main-latest
- Internal proxy on port 4000
- Converts Anthropic API to OpenAI-compatible format
- Health check with 30s intervals
- Not exposed via Traefik (internal only)
**LiteLLM Configuration (litellm-config.yaml)**
- Claude Sonnet 4 (claude-sonnet-4-20250514)
- Claude Sonnet 4.5 (claude-sonnet-4-5-20250929)
- Claude 3.5 Sonnet (claude-3-5-sonnet-20241022)
- Claude 3 Opus (claude-3-opus-20240229)
- Claude 3 Haiku (claude-3-haiku-20240307)
**Open WebUI Configuration Updates**
- Changed OPENAI_API_BASE_URLS to point to LiteLLM proxy
- URL: http://litellm:4000/v1
- Added litellm as dependency for webui service
- Dummy API key for proxy authentication
**Why LiteLLM?**
Anthropic's API uses different endpoint structure and authentication
headers compared to OpenAI. LiteLLM acts as a translation layer,
allowing Open WebUI to use Claude models through its OpenAI-compatible
interface.
**Available Models in Open WebUI**
- claude-sonnet-4 (latest Claude Sonnet 4)
- claude-sonnet-4.5 (Claude Sonnet 4.5)
- claude-3-5-sonnet
- claude-3-opus
- claude-3-haiku
