**Date**: 2025-12-06
**Status**: 60% Complete - Core Foundation, REMOTE Mode & Plugin System Implemented

---

## 🎉 Completed Implementation

### ✅ Phase 1: Core Foundation (100% Complete)

**Files Created**:
- `dss-claude-plugin/core/config.py` (166 lines)
- `dss-claude-plugin/core/context.py` (157 lines)
- `dss-claude-plugin/core/__init__.py`
- `dss-claude-plugin/strategies/base.py` (155 lines)
- `dss-claude-plugin/strategies/__init__.py`

**Capabilities**:

1. **DSSConfig** - Mode Detection System
   - ✅ Priority-based mode detection:
     1. `DSS_MODE` environment variable
     2. `~/.dss/config.json` file
     3. Auto-detect (ping localhost:6006/health)
     4. Default to REMOTE (safer)
   - ✅ Persistent session ID generation
   - ✅ Config save/load to `~/.dss/config.json`
   - ✅ Async health check with 2s timeout
   - ✅ Pydantic validation for type safety

2. **DSSContext** - Singleton Context Manager
   - ✅ Thread-safe async initialization
   - ✅ Mode-aware strategy factory
   - ✅ Capability caching (LOCAL vs REMOTE)
   - ✅ Session management
   - ✅ API URL resolution based on mode

3. **Strategy Pattern** - Abstract Base Classes
   - ✅ `BrowserStrategy` ABC:
     - `get_console_logs()` - Retrieve browser console logs
     - `capture_screenshot()` - Take screenshots
     - `get_dom_snapshot()` - Get HTML state
     - `get_errors()` - Get error logs
   - ✅ `FilesystemStrategy` ABC:
     - `read_file()` - Read file contents

### ✅ Phase 3: REMOTE Mode Implementation (100% Complete)

**Files Created**:
- `dss-claude-plugin/strategies/remote/browser.py` (172 lines)
- `dss-claude-plugin/strategies/remote/filesystem.py` (80 lines)
- `dss-claude-plugin/strategies/remote/__init__.py`

**Enhanced**:
- `admin-ui/js/core/browser-logger.js` (+98 lines)

**Capabilities**:

1. **Shadow State Pattern** (Key Innovation!)
   - ✅ Browser captures DOM snapshots on:
     - Navigation changes (1s polling for SPA support)
     - Uncaught errors (immediate capture)
     - Unhandled promise rejections
   - ✅ Snapshots include:
     - Full HTML (`document.documentElement.outerHTML`)
     - Current URL
     - Viewport dimensions (width, height, devicePixelRatio)
     - Document title
     - Timestamp
   - ✅ Beacon API for reliable sync during crashes
   - ✅ Automatic sync to `/api/browser-logs` every 30s

2. **RemoteBrowserStrategy**
   - ✅ Fetches logs from `/api/browser-logs/{session_id}`
   - ✅ Extracts Shadow State snapshots from logs
   - ✅ Filters console logs by level (log, warn, error)
   - ✅ Returns latest DOM snapshot from Shadow State
   - ✅ Handles 404 gracefully (session not found)
   - ✅ 10s timeout for API requests
   - ✅ Comprehensive error handling

3. **RemoteFilesystemStrategy**
   - ✅ Security-first design
   - ✅ All filesystem operations raise `NotImplementedError`
   - ✅ Clear error messages guiding users to LOCAL mode
   - ✅ Prevents security vulnerabilities from remote file access

### ✅ MCP Server Plugin System (100% Complete)

**Date Completed**: 2025-12-06
**Architecture Validated By**: Gemini 3 Pro Preview (Deep Thinking + Expert Analysis)
**Expert Improvements Implemented**: 2025-12-06

**Files Created**:
- `tools/dss_mcp/plugin_registry.py` (267 lines)
- `tools/dss_mcp/plugins/__init__.py` (documentation)
- `tools/dss_mcp/plugins/_template.py` (comprehensive template)
- `tools/dss_mcp/plugins/hello_world.py` (test plugin)

**Files Modified**:
- `tools/dss_mcp/server.py` (+5 lines for plugin integration)

**Capabilities**:

1. **Dynamic Plugin Loading**
   - ✅ Auto-discovers `.py` files in `/plugins/` directory
   - ✅ Uses Python's `pkgutil` and `importlib` for dynamic import
   - ✅ Validates plugin contract (TOOLS list + handler class)
   - ✅ Detects and prevents tool name collisions
   - ✅ Comprehensive error handling (plugin errors don't crash server)
   - ✅ Loads plugins at server startup (zero-config)

2. **Plugin Contract** (Simple & Documented)
   ```python
   # Required exports:
   TOOLS = [types.Tool(...)]  # MCP tool definitions
   class PluginTools:         # Handler class with execute_tool() method
       async def execute_tool(self, name, args): pass

   # Optional export:
   PLUGIN_METADATA = {...}    # Name, version, author
   ```

3. **PluginRegistry Class**
   - ✅ `load_plugins()` - Auto-discovers and registers plugins
   - ✅ `_register_module()` - Validates and registers single plugin
   - ✅ `_find_and_instantiate_handler()` - Finds handler class
   - ✅ `execute_tool()` - Routes tool calls to correct plugin
   - ✅ `get_all_tools()` - Returns merged tool list
   - ✅ `get_plugin_info()` - Returns plugin metadata
   - ✅ `reload_plugins()` - Hot-reload for development

4. **Server Integration** (Minimal Changes)
   - ✅ Import: `from .plugin_registry import PluginRegistry`
   - ✅ Initialize: `plugin_registry = PluginRegistry()` + `load_plugins()`
   - ✅ List tools: `tools.extend(plugin_registry.get_all_tools())`
   - ✅ Route calls: Check `plugin_registry.handlers` and execute
   - ✅ Zero breaking changes to existing code

5. **Developer Workflow**
   ```bash
   # 1. Copy template
   cp plugins/_template.py plugins/my_plugin.py

   # 2. Edit plugin (define TOOLS and PluginTools)
   vim plugins/my_plugin.py

   # 3. Restart server
   supervisorctl restart dss-mcp

   # 4. Plugin tools instantly available to all clients!
   ```

6. **Testing & Validation**
   - ✅ Created hello_world.py test plugin (2 tools)
   - ✅ Validated plugin loading via Python test script
   - ✅ Confirmed tools registered correctly
   - ✅ Verified handler routing works
   - ✅ All edge cases handled (name collisions, errors, etc.)

**Key Innovations**:

1. **Drop-In Pattern**: Developers add plugins by dropping .py files in directory - no registration needed
2. **Error Isolation**: Plugin load failures logged but don't crash server
3. **Zero Configuration**: Plugins auto-discovered on startup
4. **Hot Reload Support**: `reload_plugins()` method for development
5. **Comprehensive Template**: `_template.py` serves as both docs and starting point

**Expert Improvements (2025-12-06)**:

After external validation, three critical improvements were implemented:

1. **🔴 Async Contract Enforcement** (HIGH PRIORITY - IMPLEMENTED)
   - Added `inspect.iscoroutinefunction()` check in `_register_module()`
   - Prevents runtime TypeError when server tries to await non-async methods
   - Plugin loading now fails fast with clear error message
   - Lines added: plugin_registry.py:131-138

2. **✅ Runtime Error Isolation** (HIGH PRIORITY - ALREADY PRESENT)
   - server.py already has comprehensive try/except in call_tool() (lines 250-284)
   - Plugin exceptions caught and logged, preventing server crashes
   - Confirmed: Production-ready error handling ✓

3. **🟡 Dependency Management Convention** (MEDIUM PRIORITY - IMPLEMENTED)
   - Created `install_plugin_deps.sh` script for automated dependency installation
   - Scans plugins/ directory for requirements.txt files
   - Updated plugins/__init__.py with dependency management workflow
   - Convention: Each plugin subdirectory can have its own requirements.txt
   - Example: `plugins/my_plugin/requirements.txt`

**Files Added**:
- `tools/install_plugin_deps.sh` (executable script, 80 lines)

**Files Enhanced**:
- `plugin_registry.py` (+7 lines for async validation)
- `plugins/__init__.py` (+17 lines for dependency docs)

   - Connect to Chrome via CDP (localhost:9222)
   - Real-time console log capture
   - Live screenshot capture
   - DOM snapshot via CDP

2. **LocalFilesystemStrategy**
   - Direct filesystem read/write
   - Path.glob() for file search
   - os.stat() for file metadata

**Dependencies**:
- `playwright` - Browser automation
- May require Chrome with `--remote-debugging-port=9222`

### Phase 4: Commands & Plugin Integration

## 🚀 Key Innovations Implemented

### 1. Shadow State Pattern
The biggest innovation! Bridges LOCAL (query-based) and REMOTE (event-based):
- Browser automatically captures DOM on significant events
- REMOTE mode can query "browser state" like LOCAL queries CDP
- Reliable delivery via Beacon API during crashes

### 2. Adaptive Strategy Pattern
- Same commands work in both LOCAL and REMOTE modes
- Zero breaking changes to existing plugin
- Transparent mode switching

### 3. Security-First REMOTE Design
- Filesystem operations explicitly disabled in REMOTE
- Clear error messages guide users to LOCAL mode
- No accidental security vulnerabilities

1. Open https://dss.overbits.luz.uy in browser
2. Browser-logger.js auto-loads and starts capturing
3. Navigate around (triggers Shadow State snapshots)
4. Logs auto-sync every 30s

# Test from CLI (once commands are implemented)
dss-config set remote
dss-status  # Should show REMOTE mode
dss-logs --session latest  # Should return browser logs
```

---

## 🏪 Internal Plugin Marketplace Architecture

**Date**: 2025-12-06
**Status**: ✅ Analysis Complete - **CORRECTED FOR INTERNAL USE**
**Document**: [INTERNAL_PLUGIN_MARKETPLACE.md](.dss/INTERNAL_PLUGIN_MARKETPLACE.md)

### Decision: Server-Side Plugin Loading (Not GitHub Marketplace)

**Clarification**: DSS is **internal-only** for team use. The GitHub marketplace approach was over-engineered.

**Question**: How should we distribute plugins internally?

**Answer**: **Server-Side Plugin Directory** with auto-loading via `plugin_loader.py`

### Key Architecture

```
┌─────────────────────────────────────┐
│  DSS Server (dss.overbits.luz.uy)  │
│                                      │
│  /plugins/                          │
│  ├── network-logger/                │
│  ├── performance-analyzer/          │
│  └── custom-workflow/               │
│         ↓                            │
│  plugin_loader.py (auto-discovery)  │
│         ↓                            │
│  DSS MCP Server (exposes all tools) │
└─────────────┬───────────────────────┘
              │
              ↓
    Developer connects
    → All plugins instantly available
    → Zero installation needed
```

### Key Advantages

1. ✅ **Zero Client Setup** - No installation on developer machines
2. ✅ **Central Management** - Update plugins server-side, all devs get updates
3. ✅ **Instant Availability** - Connect to MCP → all plugins ready
4. ✅ **Team Consistency** - Everyone uses exact same toolset
5. ✅ **Simple Development** - Copy template, edit, restart server
6. ✅ **Works with REMOTE/LOCAL** - Plugins use existing Strategy Pattern

### Implementation Plan

| Phase | Component | Effort | Status |
|-------|-----------|--------|--------|
| 1 | **Plugin Loader (Deferred Registration)** | 1 day | 🔴 **CRITICAL** |
| 2 | Plugin Directory + Template | 0.5 day | 🟡 High Priority |
| 3 | Example Plugins (network-logger, etc.) | 1 day | 🟢 Medium Priority |
| 4 | Discovery API (optional) | 0.5 day | 🔵 Low Priority |

**Total Effort**: 2-3 days
**Confidence**: Very High (95%+)
**Validated By**: Gemini 3 Pro Preview + Expert Analysis

### Critical Pattern: Deferred Registration

FastMCP requires dynamic tool registration. Plugins export `TOOLS` list, loader applies `@mcp.tool()` decorator at runtime.

**Developer Workflow**:
```bash
# 1. Copy template
cp -r /plugins/_template /plugins/my-plugin

# 2. Edit files
vim /plugins/my-plugin/__init__.py
vim /plugins/my-plugin/tools.py

# 3. Restart server
sudo supervisorctl restart dss-mcp

# 4. Plugin available to all devs!
```
