# Plugins Directory Audit

**Date:** 2025-01-07
**Auditor:** Claude (Audit Mode)
**Scope:** plugins/ directory and core/plugins/ infrastructure

---

## Executive Summary

All analyzed plugins are **correctly placed** as plugins. The plugin architecture is well-designed with clear separation between core infrastructure (core/plugins/) and optional features (plugins/).

**Key Findings:**
- 9/9 plugins correctly classified as PLUGIN
- 0 plugins need to move to core
- 1 plugin (system_commands) wraps core functionality but is still appropriate as a plugin
- core/plugins/ infrastructure is correctly placed as CORE

---

## Core Plugin Infrastructure (core/plugins/)

**VERDICT: CORRECTLY PLACED AS CORE**

The plugin SYSTEM infrastructure is properly located in core/plugins/. These files provide the essential plugin loading mechanism that the application requires to support plugins at all.

| File | Classification | Reason |
|------|---------------|--------|
| `factory.py` | CORE | Plugin instantiation with dependency injection - required for any plugin to work |
| `discovery.py` | CORE | File system scanning and module loading - required for plugin discovery |
| `registry.py` | CORE | Plugin registry coordination - central plugin system coordinator |
| `collector.py` | CORE | Plugin status aggregation - required for plugin status reporting |

**Assessment:** These components form the plugin infrastructure itself. Without them, the plugin system cannot function. They are correctly placed in core.

## Plugins Analysis (plugins/)

### 1. Enhanced Input Plugin
**Location:** `plugins/enhanced_input_plugin.py` (with `plugins/enhanced_input/` subdirectory)

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional visual enhancement - bordered input boxes using Unicode
complexity: low
dependencies: core/io/visual_effects, core/events
```

**Analysis:**
- Renders fancy bordered input boxes with Unicode characters
- Purely cosmetic enhancement to input rendering
- Application functions perfectly without it (basic input still works)
- Excellent example of plugin architecture with modular components
- Uses hook system appropriately (INPUT_RENDER hook)

**Verdict:** CORRECTLY PLACED - Optional UI enhancement, not required for core functionality.

---

### 2. Hook Monitoring Plugin
**Location:** `plugins/hook_monitoring_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Development/debugging tool - demonstrates plugin ecosystem features
complexity: low
dependencies: core/events, core/llm/plugin_sdk
```

**Analysis:**
- Development and debugging tool for monitoring hook execution
- Labeled as "SHOWCASE" plugin demonstrating all plugin ecosystem features
- Optional - not needed for production use
- Provides plugin discovery, service registration, cross-plugin communication demos

**Verdict:** CORRECTLY PLACED - Optional development tool, should remain a plugin.

---

### 3. Query Enhancer Plugin
**Location:** `plugins/query_enhancer_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional feature - uses fast model to enhance user queries
complexity: low
dependencies: aiohttp, core/events
```

**Analysis:**
- Optional feature that uses a fast local model to enhance user queries
- Disabled by default (enabled: False in default config)
- Application works without it
- User-controlled feature

**Verdict:** CORRECTLY PLACED - Optional enhancement feature, appropriate as plugin.

---

### 4. Save Conversation Plugin
**Location:** `plugins/save_conversation_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional feature - /save command for exporting conversations
complexity: low
dependencies: core/commands, core/io/visual_effects
```

**Analysis:**
- Implements `/save` command for exporting conversations
- Export functionality is optional
- App functions without save capability
- Multiple export formats (transcript, markdown, jsonl, raw)

**Verdict:** CORRECTLY PLACED - Optional feature, not core requirement.

---

### 5. Resume Conversation Plugin
**Location:** `plugins/resume_conversation_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional feature - session management and branching
complexity: medium
dependencies: core/models/resume, core/events, core/commands
```

**Analysis:**
- Implements `/resume`, `/sessions`, `/branch` commands
- Session management and conversation history
- Optional feature - app works for new conversations without it
- Useful but not essential for core chat functionality

**Verdict:** CORRECTLY PLACED - Advanced feature that enhances but is not required for basic operation.

---

### 6. Workflow Enforcement Plugin
**Location:** `plugins/workflow_enforcement_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional development tool - enforces todo list completion
complexity: medium
dependencies: core/events, core/io/visual_effects
```

**Analysis:**
- Detects todo lists in LLM responses and enforces sequential completion
- Development workflow tool
- Disabled by default
- App functions without it
- Enforces specific development practices

**Verdict:** CORRECTLY PLACED - Optional workflow tool, not required for core functionality.

---

### 7. System Commands Plugin
**Location:** `plugins/system_commands_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE) - but note: wraps CORE functionality
reason: Wrapper for core system commands (/help, /config, /status)
complexity: low
dependencies: core/commands/system_commands (CORE)
```

**Analysis:**
- Thin wrapper around `CoreSystemCommandsPlugin` from `core/commands/system_commands.py`
- Registers essential UI commands: /help, /config, /status
- The actual implementation is in CORE, this is just a plugin wrapper
- Could be argued these commands should always be available

**Verdict:** CORRECTLY PLACED but worth discussion. The plugin wraps core functionality. The commands themselves are essential (help, config, status), but the plugin wrapper approach allows the command system to remain plugin-based.

**Recommendation:** Consider making system commands always-loaded by moving registration to core initialization, rather than discovering as a plugin.

---

### 8. Tmux Plugin
**Location:** `plugins/tmux_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Optional external system integration - tmux session management
complexity: medium
dependencies: subprocess, core/events, core/io/visual_effects
```

**Analysis:**
- Tmux session management and live viewing
- External system integration
- Platform-specific (requires tmux)
- Optional feature - not everyone uses tmux
- App functions without it

**Features:**
- Create/view/list/kill tmux sessions
- Live modal view with real-time streaming
- Isolated tmux server (configurable via `use_separate_server`)
- Session cycling with keyboard navigation
- Configurable capture lines (default: 200)

**Config Options:**
```json
{
  "plugins": {
    "tmux": {
      "enabled": true,
      "show_status": true,
      "refresh_rate": 0.1,
      "capture_lines": 200,
      "use_separate_server": true,
      "socket_name": "kollabor"
    }
  }
}
```

**Verdict:** CORRECTLY PLACED - Perfect example of a plugin - optional external integration.

---

### 9. Matrix Plugin (Fullscreen)
**Location:** `plugins/fullscreen/matrix_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE)
reason: Purely cosmetic visual effect
complexity: low
dependencies: core/fullscreen, core/fullscreen/components/matrix_components
```

**Analysis:**
- Matrix rain digital rain effect
- Purely visual/easter egg
- Implemented using FullScreenPlugin framework
- Definitely optional

**Verdict:** CORRECTLY PLACED - Visual effect, clearly a plugin.

---

### 10. Setup Wizard Plugin (Fullscreen)
**Location:** `plugins/fullscreen/setup_wizard_plugin.py`

```
current: PLUGIN
should_be: PLUGIN (NO CHANGE) - but note: first-run onboarding
reason: Interactive setup wizard for first-time configuration
complexity: medium
dependencies: core/fullscreen, core/config
```

**Analysis:**
- First-time user onboarding wizard
- Interactive LLM connection configuration
- Shows keyboard shortcuts and slash commands
- Essential for new user experience but technically optional
- Runs once, then marks setup complete

**Verdict:** CORRECTLY PLACED. While important for UX, it's an optional onboarding flow. The app can be configured manually via config files.

| Setup Wizard | plugins/fullscreen/ | YES | Onboarding flow, technically optional |

**Overall Assessment:** All plugins are correctly placed. The plugin architecture is well-designed and consistently applied.

---

## Recommendations

1. **Keep current structure** - No plugins need to move to core.

2. **Consider system_commands approach** - The plugin wrapper for core system commands works but could be simplified. Consider making essential commands (/help, /config, /status) always-loaded in core rather than discovered as plugins.

3. **Continue modular design** - The enhanced_input plugin's modular approach (separate components) is excellent and should be emulated in other complex plugins.

4. **Plugin documentation** - Hook monitoring plugin serves as an excellent showcase/example. Consider adding a "plugins/examples/" directory with template plugins for developers.

5. **Plugin testing** - Each plugin should have corresponding tests. Verify test coverage for all plugins.

## Audit Methodology

This audit followed the criteria in `docs/CORE_VS_PLUGIN_AUDIT_SPEC.md`:

**Core Criteria (must stay in core/):**
- Application lifecycle (startup, shutdown, cleanup)
- Event bus infrastructure
- Plugin loading/discovery mechanism
- Base classes and interfaces
- Terminal I/O primitives
- Configuration loading/saving infrastructure
- State persistence infrastructure
- Basic LLM API communication

**Plugin Criteria (should be a plugin):**
- Specific visual effects (matrix rain, gradients, animations)
- Specific commands (/save, /matrix, /terminal, etc.)
- Enhanced input features (multi-line, syntax highlighting)
- Status line customizations
- Specific hooks implementations
- Model routing strategies
- Export formats
- UI widgets beyond basics
- MCP integrations
- Tool implementations

All plugins in `plugins/` satisfy the Plugin Criteria and do not satisfy Core Criteria.
