+# Claude Code Instructions
+
+## Plugin Development Workflow
+
+When creating, modifying, or removing plugins:
+
+1. **Always update the plugin documentation** in `docs/plugins.md` after any plugin changes
+2. Ensure the documentation includes:
+   - Plugin name and category (Development, Fun and entertainment, Utility, Security, Social Media)
+   - Brief description of functionality
+   - Usage instructions with examples
+   - Any configuration requirements
+3. **For plugins with configuration options:**
+   - Set `ConfigRequired: true` in the plugin's BasePlugin struct
+   - Add corresponding HTML form fields in `internal/admin/templates/channel_plugin_config.html`
+   - Use conditional template logic: `{{else if eq .ChannelPlugin.PluginID "plugin.id"}}`
+   - Include proper form labels, help text, and value binding
+
+## Testing
+
+**CRITICAL**: After making ANY changes to code files, you MUST run these commands in order:
+
+1. **Format code**: `make format` - Format all code according to project standards
+2. **Lint code**: `make lint` - Check code style and quality (must show "0 issues")
+3. **Run tests**: `make test` - Run all tests to ensure functionality works
+4. Verify documentation accuracy
+5. Ensure all examples work as described
+
+**These commands are MANDATORY after every code change, no exceptions.**

 - Remind Me: Reply to a message with `!remindme <duration>` to set a reminder. Supported duration units: y (years), mo (months), d (days), h (hours), m (minutes), s (seconds). Examples: `!remindme 1y` for 1 year, `!remindme 3mo` for 3 months, `!remindme 2d` for 2 days, `!remindme 3h` for 3 hours. The bot will mention you with a reminder after the specified time.
+- Search and Replace: Reply to any message with `s/search/replace/[flags]` to perform text substitution. Supports flags: `g` (global), `i` (case insensitive), `n` (regex pattern). Example: `s/hello/hi/gi` replaces all occurrences of "hello" with "hi" case-insensitively.
