```
use provisioning/core/plugins/nushell-plugins/nu_plugin_tera
template render "config.j2" $variables
```

**Location**: `provisioning/core/plugins/nushell-plugins/nu_plugin_tera/`

### ✅ Fully Implemented

#### nu_plugin_auth (Authentication Services)

**Status**: PRODUCTION-READY

**Capabilities**:
- ✅ JWT token generation and validation
- ✅ TOTP/OTP support
- ✅ Session management
- ✅ Multi-factor authentication

**Usage**:
```
provisioning auth verify-token $token
provisioning auth generate-jwt --user alice
provisioning auth enable-mfa --type totp
```

**Location**: `provisioning/core/plugins/nushell-plugins/nu_plugin_auth/`

#### nu_plugin_kms (Key Management)

**Status**: PRODUCTION-READY

**Capabilities**:
- ✅ Encryption/decryption using KMS
- ✅ Key rotation management
- ✅ Secure secret storage
- ✅ Hardware security module (HSM) support

**Usage**:
```
provisioning kms encrypt --key primary "secret data"
provisioning kms decrypt "encrypted:..."
provisioning kms rotate --key primary
```

**Related Tools**:
- SOPS for secret encryption
- Age for file encryption
- SecretumVault for secret management (see [ADR-014](../architecture/adr/adr-014-secretumvault-integration.md))

**Location**: `provisioning/core/plugins/nushell-plugins/nu_plugin_kms/`

#### nu_plugin_orchestrator (Workflow Orchestration)

**Status**: PRODUCTION-READY

**Capabilities**:
- ✅ Workflow definition and execution
- ✅ Multi-step infrastructure provisioning
- ✅ Dependency management
- ✅ Error handling and retries
- ✅ Progress monitoring

**Usage**:
```
provisioning orchestrator status
provisioning workflow execute deployment.nu
provisioning workflow list
```

**Supported Workflows**:
- Nushell workflows (`.nu`) - `provisioning/core/nulib/workflows/`
- Nickel workflows (`.ncl`) - `provisioning/schemas/workflows/`

**Location**: `provisioning/core/plugins/nushell-plugins/nu_plugin_orchestrator/`

## Plugin Architecture

### Three-Tier Approach

1. **Tier 1: Nushell Plugins** (Native, fastest)
   - Compiled Rust or pure Nushell
   - Direct integration
   - Maximum performance

2. **Tier 2: HTTP Fallback** (Current, reliable)
   - Service-based
   - Network-based communication
   - Available now

3. **Tier 3: Manual Implementation** (Documented, flexible)
   - User-provided implementations
   - Custom integrations
   - Last resort

### Integration Points

**Help System**: Plugins are referenced in help system
- `provisioning help plugins` - Plugin status and usage

**Commands**: Plugin commands integrated as native provisioning commands
- `provisioning auth verify-token`
- `provisioning kms encrypt`
- `provisioning orchestrator status`

**Configuration**: Plugin settings in provisioning configuration
- `provisioning/config/config.defaults.toml` - Plugin defaults
- User workspace config - Plugin overrides

## Development Roadmap

### Phase 1: HTTP Fallback (✅ COMPLETE)

Fallback implementations allow core functionality without native plugins.

### Phase 2: Plugin Framework (🟡 IN PROGRESS)

- Plugin discovery and loading
- Configuration system
- Error handling framework
- Testing infrastructure

### Phase 3: Native Plugins (PLANNED)

- nu_plugin_auth compilation
- nu_plugin_kms implementation
- nu_plugin_orchestrator integration

### Phase 4: Integration (PLANNED)

- Help system integration
- Command aliasing
- Performance optimization
- Documentation and examples

## Using Plugins Today

### Available

```
# Template rendering (nu_plugin_tera)
provisioning config generate --template workspace.j2

# Help system shows plugin status
provisioning help plugins
```

### Fallback (HTTP-based)

```
# Authentication (HTTP fallback)
provisioning auth verify-token $token

# KMS (HTTP fallback)
provisioning kms encrypt --key mykey "secret"

# Orchestrator (HTTP fallback)
provisioning orchestrator status
```

### Manual Nushell Workflows

```
# Use Nushell workflows instead of plugins
provisioning workflow list
provisioning workflow execute deployment.nu
```

## Plugin Development Guide

To develop a plugin:

1. **Use Existing Patterns**: Study nu_plugin_tera implementation
2. **Implement HTTP Fallback**: Ensure HTTP fallback works first
3. **Create Native Plugin**: Build Rust or Nushell-based plugin
4. **Integration Testing**: Test with help system and CLI
5. **Documentation**: Update this roadmap and plugin help

See [Plugin Development Guide](../development/plugin-development.md) (when available).

## Troubleshooting

### Plugin Not Found

**Problem**: `Command 'auth' not found`

**Solution**:
1. Check HTTP server is running: `provisioning status`
2. Check fallback implementation: `provisioning help auth`
3. Verify configuration: `provisioning validate config`

### Plugin Timeout

**Problem**: Command times out or hangs

**Solution**:
1. Check HTTP server health: `curl http://localhost:8080/health`
2. Check network connectivity: `ping localhost`
3. Check logs: `provisioning status --verbose`
4. Report issue with full debug output

### Plugin Not in Help

**Problem**: Plugin commands don't appear in `provisioning help`

**Solution**:
1. Check plugin is loaded: `provisioning list-plugins`
2. Check help system: `provisioning help | grep plugin`
3. Check configuration: `provisioning validate config`
