Problem Statement

Auto-Claude is a powerful autonomous coding framework, but currently all features must be built into the core application. This limits:

1. Community contributions - External developers can't easily add features
2. Customization - Users can't tailor the app to their specific workflows
3. Maintainability - Core team must maintain all features
4. Experimentation - New ideas require core changes

Many successful developer tools (VS Code, Obsidian, Figma) thrive because of their plugin ecosystems.

Proposed Feature

Introduce a Plugin System Architecture that allows:

• Third-party developers to create plugins
• Users to install/enable/disable plugins
• Plugins to extend UI, commands, and workflows
• Safe sandboxed execution

High-Level Architecture

Core Components:

• Plugin SDK - TypeScript types, context API, lifecycle hooks
• Plugin Loader - Discovery, validation, activation
• Contribution Registry - Commands, panels, settings, menus

Extension Points:

• Commands (Command Palette)
• Sidebar Panels
• Settings Sections
• Keybindings
• Menu Items
• Task Validators
• Context Providers

Plugin Manifest Format

json
{
"id": "my-plugin",
"name": "My Plugin",
"version": "1.0.0",
"main": "dist/main.js",
"contributes": {
"commands": [],
"sidebar": { "panels": [] },
"settings": { "sections": [] }
},
"activationEvents": ["onStartup"],
"permissions": ["filesystem", "network"]
}

Plugin Lifecycle

INSTALLED → LOADED → ACTIVATING → ACTIVE → DEACTIVATING → INACTIVE

Security Model

1. Manifest Permissions - Plugins declare required permissions
2. Permission Validation - User approves permissions on install
3. Sandboxed Context - Plugins receive limited API access
4. Error Isolation - Failed plugins don't crash the host

Reference Implementation

I've created a complete working implementation:

How This Enhances Existing Features

Example Plugins Made Possible

• Flowchart Importer (Feature Request: Flowchart Importer (Lucidchart XML → Agent Task Graph & Code) #1418) - Import visual workflows as tasks

Contribution Plan

I've implemented a complete working version and I'm happy to:

1. Submit this as a PR if it aligns with the project direction
2. Iterate based on maintainer feedback
3. Help document and support community plugin development
