+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is an Alfred preferences sync repository. It contains Alfred workflows, snippets, and preferences that are version-controlled via git and synced across machines.
+
+**Directory Structure:**
+- `Alfred.alfredpreferences/` - Main Alfred preferences package
+  - `workflows/` - Alfred workflows (UUID-named directories, each containing `info.plist`)
+  - `snippets/` - Text snippet collections (JSON files with Alfred snippet format)
+  - `preferences/` - General Alfred preferences (`prefs.plist`, features, etc.)
+  - `resources/` - Alfred resources (icons, images)
+  - `remote/` - Remote sync data
+- `alfred-sync.sh` - Git sync script
+
+## Syncing Changes
+
+To commit and push Alfred preference changes:
+
+```bash
+./alfred-sync.sh
+```
+
+This script stages all changes, creates a timestamped commit, and pushes to the remote repository.
+
+## Alfred Workflow Structure
+
+Each workflow is stored in `workflows/user.workflow.{UUID}/` and contains:
+- `info.plist` - Main workflow configuration (name, objects, connections, script definitions)
+
+Workflows are defined as XML plist files containing:
+- Workflow metadata (name, bundleid, createdby)
+- Objects (script actions, inputs, outputs, notifications)
+- Connections between objects
+- UI layout data (uidata)
+
+## Snippet Collections
+
+Snippets are organized in themed collections under `snippets/`:
+- `術語速查字典/` - Technical terminology cheat sheets
+- `中文輸出速查/` - Chinese text output shortcuts
+- `特殊字元輸出集/` - Special character collections
+- `topsecret/` - Sensitive credentials (be cautious when committing)
+
+Each snippet is a JSON file with the structure:
+```json
+{
+  "alfredsnippet": {
+    "snippet": "expansion text",
+    "uid": "UUID",
+    "name": "display name",
+    "keyword": "trigger keyword"
+  }
+}
+```
+
+## Notes
+
+- The `Alfred.alfredpreferences` directory is macOS package format
+- Workflow UUIDs are generated by Alfred and should not be changed
+- When editing workflows, ensure plist XML syntax remains valid
+- Be mindful of sensitive data in snippets (especially `topsecret/` collection)

+# Quick Start
+
+Get your Alfred preferences synced in a few steps.
+
+## Initial Setup
+
+### 1. Clone the Repository
+
+```bash
+git clone <your-repo-url> ~/Sync/AlfredPrefs
+cd ~/Sync/AlfredPrefs
+```
+
+### 2. Link Alfred Preferences
+
+Replace Alfred's default preferences with a symlink to this repository:
+
+```bash
+# Backup existing preferences first (if they exist)
+mv ~/Library/Application\ Support/Alfred/Alfred.alfredpreferences \
+   ~/Library/Application\ Support/Alfred/Alfred.alfredpreferences.backup
+
+# Create the symlink
+ln -s ~/Sync/AlfredPrefs/Alfred.alfredpreferences \
+   ~/Library/Application\ Support/Alfred/Alfred.alfredpreferences
+```
+
+### 3. Restart Alfred
+
+Quit and relaunch Alfred. Your workflows and snippets will now be loaded from this repository.
+
+## Daily Usage
+
+### Sync Your Changes
+
+After modifying workflows or snippets in Alfred:
+
+```bash
+cd ~/Sync/AlfredPrefs
+./alfred-sync.sh
+```
+
+That's it! Your changes are now committed and pushed.
+
+### Pull Changes from Another Machine
+
+```bash
+cd ~/Sync/AlfredPrefs
+git pull
+```
+
+Then restart Alfred to load the updated preferences.
+
+## Sync Script
+
+The `alfred-sync.sh` script does the following:
+
+```bash
+cd /Users/timmy/Sync/AlfredPrefs
+git add -A
+git commit -m "sync YYYY-MM-DD HH:MM"
+git push
+```
+
+Customize the path in the script if your repository location differs.
+
+## Troubleshooting
+
+**Alfred doesn't show new workflows**
+- Restart Alfred from the menu bar
+- Check that the symlink is correctly created
+
+**Sync fails**
+- Ensure you have git access to the repository
+- Check your SSH keys or authentication
+
+**Changes not appearing**
+- Run `git pull` to get latest changes
+- Restart Alfred after pulling
