+# Fabric Extensions: Complete Guide
+
+## Understanding Extension Architecture
+
+### Registry Structure
+The extension registry is stored at `~/.config/fabric/extensions/extensions.yaml` and tracks registered extensions:
+
+```yaml
+extensions:
+    extension-name:
+        config_path: /path/to/config.yaml
+        config_hash: <sha256>
+        executable_hash: <sha256>
+```
+
+The registry maintains security through hash verification of both configs and executables.
+
+### Extension Configuration
+Each extension requires a YAML configuration file with the following structure:
+
+```yaml
+name: "extension-name"          # Unique identifier
+executable: "/path/to/binary"   # Full path to executable
+type: "executable"             # Type of extension
+timeout: "30s"                 # Execution timeout
+description: "Description"     # What the extension does
+version: "1.0.0"              # Version number
+env: []                       # Optional environment variables
+
+operations:                   # Defined operations
+  operation-name:
+    cmd_template: "{{executable}} {{operation}} {{value}}"
+
+config:                      # Output configuration
+  output:
+    method: "stdout"         # or "file"
+    file_config:            # Optional, for file output
+      cleanup: true
+      path_from_stdout: true
+      work_dir: "/tmp"
+```
+
+### Directory Structure
+Recommended organization:
+```
+~/.config/fabric/extensions/
+├── bin/           # Extension executables
+├── configs/       # Extension YAML configs
+└── extensions.yaml # Registry file
+```
+
+## Example 1: Python Wrapper (Word Generator)
+A simple example wrapping a Python script.
+
+### 1. Position Files
+```bash
+# Create directories
+mkdir -p ~/.config/fabric/extensions/{bin,configs}
+
+# Install script
+cp word-generator.py ~/.config/fabric/extensions/bin/
+chmod +x ~/.config/fabric/extensions/bin/word-generator.py
+```
+
+### 2. Configure
+Create `~/.config/fabric/extensions/configs/word-generator.yaml`:
+```yaml
+name: word-generator
+executable: "~/.config/fabric/extensions/bin/word-generator.py"
+type: executable
+timeout: "5s"
+description: "Generates random words based on count parameter"
+version: "1.0.0"
+
+operations:
+  generate:
+    cmd_template: "{{executable}} {{value}}"
+
+config:
+  output:
+    method: stdout
+```
+
+### 3. Register & Run
+```bash
+# Register
+fabric --addextension ~/.config/fabric/extensions/configs/word-generator.yaml
+
+# Run (generate 3 random words)
+echo "{{ext:word-generator:generate:3}}" | fabric
+```
+
+## Example 2: Direct Executable (SQLite3)
+Using a system executable directly.
+
+copy the memories to your home directory
+ ~/memories.db
+
+### 1. Configure
+Create `~/.config/fabric/extensions/configs/memory-query.yaml`:
+```yaml
+name: memory-query
+executable: "/usr/bin/sqlite3"
+type: executable
+timeout: "5s"
+description: "Query memories database"
+version: "1.0.0"
+
+operations:
+  goal:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where type= 'goal'\""
+  value:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where type= 'value'\""
+  byid:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where uid= {{value}}\""
+  all:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories\""
+
+config:
+  output:
+    method: stdout
+```
+
+### 2. Register & Run
+```bash
+# Register
+fabric --addextension ~/.config/fabric/extensions/configs/memory-query.yaml
+
+# Run queries
+echo  "{{ext:memory-query:all}}" | fabric
+echo  "{{ext:memory-query:byid:3}}" | fabric
+```
+
+
+## Extension Management Commands
+
+### Add Extension
+```bash
+fabric --addextension ~/.config/fabric/extensions/configs/memory-query.yaml
+```
+
+Note : if the executable or config file changes, you must re-add the extension.
+This will recompute the hash for the extension.
+
+
+### List Extensions
+```bash
+fabric --listextensions
+```
+Shows all registered extensions with their status and configuration details.
+
+### Remove Extension
+```bash
+fabric --rmextension <extension-name>
+```
+Removes an extension from the registry.
+
+
+## Extensions in patterns
+
+```
+Create a pattern that use multiple extensions.
+
+These are my favorite
+{{ext:word-generator:generate:3}}
+
+These are my least favorite
+{{ext:word-generator:generate:2}}
+
+what does this say about me?
+```
+
+```bash
+./fabric -p ./plugins/template/Examples/test_pattern.md
+```
+
+## Security Considerations
+
+1. **Hash Verification**
+   - Both configs and executables are verified via SHA-256 hashes
+   - Changes to either require re-registration
+   - Prevents tampering with registered extensions
+
+2. **Execution Safety**
+   - Extensions run with user permissions
+   - Timeout constraints prevent runaway processes
+   - Environment variables can be controlled via config
+
+3. **Best Practices**
+   - Review extension code before installation
+   - Keep executables in protected directories
+   - Use absolute paths in configurations
+   - Implement proper error handling in scripts
+   - Regular security audits of registered extensions
+
+## Troubleshooting
+
+### Common Issues
+1. **Registration Failures**
+   - Verify file permissions
+   - Check executable paths
+   - Validate YAML syntax
+
+2. **Execution Errors**
+   - Check operation exists in config
+   - Verify timeout settings
+   - Monitor system resources
+   - Check extension logs
+
+3. **Output Issues**
+   - Verify output method configuration
+   - Check file permissions for file output
+   - Monitor disk space for file operations
+
+### Debug Tips
+1. Enable verbose logging when available
+2. Check system logs for execution errors
+3. Verify extension dependencies
+4. Test extensions with minimal configurations first
+
