fix: Prevent script exit on benign errors from distrobox-upgrade during signal update

.github/prompts/removefabric.prompt.md

@@ -0,0 +1,11 @@
+Create a portable bash shell script to safely uninstall the Fabric AI CLI and related packages on Debian, Ubuntu, and Fedora systems. The script must:
+
+- Detect the operating system and select the appropriate package manager (`apt`, `dnf`, or `yum`).
+- Uninstall Fabric packages installed via system package managers and Python package managers (`pip`, `pip3`).
+- Check for errors after each removal step; abort the script if a critical error occurs.
+- Prompt the user for confirmation before making any changes.
+- Advise the user to reboot the system if required after uninstallation.
+- Log all actions and errors to a user-specified log file.
+- Be fully self-contained and compatible with bash.
+
+Reference the official [Fabric documentation](https://github.com/danielmiessler/Fabric) and your distribution’s package manager documentation for implementation details.

-## AI Integration
-
-This repository includes a complete AI development environment with Fabric integration for AI-assisted development tasks.
-
-### Fabric Setup
-
-The system includes:
-
-- **Fabric v1.4.195** with 216+ AI patterns for text processing
-- **Google Gemini 2.5 Pro** as primary AI provider
-- **External AI providers** support for flexibility
-- **Custom shell configuration** for optimal development experience
-
-### Basic Fabric Usage
-
-```bash
-# List all available patterns
-fabric -l
-
-# Use a pattern (configure your preferred AI provider)
-echo "Your text here" | fabric -p summarize
-
-# Use with specific model
-echo "Your text here" | fabric -p summarize -m gemini-2.0-flash-exp
-
-# Update patterns
-fabric -U
-```
-
-### Popular AI Patterns
-
-- `summarize` - Summarize text content
-- `explain_code` - Explain code snippets and logic
-- `improve_writing` - Enhance writing quality and clarity
-- `extract_wisdom` - Extract key insights from content
-- `create_quiz` - Generate quiz questions from text
-- `analyze_claims` - Analyze and fact-check claims
-
-### Configuration Files
-
-- **Fabric config**: `~/.config/fabric/.env` - AI provider settings and API keys
-- **Shell config**: `~/.zshrc` - Main shell configuration
-
-For complete setup instructions, see the setup documentation.
