Review this specification for EPMCDME-10900:

Technical Specification: Gemini Agent Plugin

Overview:
Add GeminiPlugin to support Google AI's Gemini models as an alternative agent option.

Architecture:
- Implement GeminiPlugin class in src/agents/plugins/gemini/
- Extend BaseAgentAdapter from src/agents/core/
- Register plugin in AgentRegistry initialization
- CLI commands route through registry (no direct plugin access)

Installation:
- Check if @google/generative-ai package installed
- Install globally via npm if missing
- Use commandExists() and installGlobal() from src/utils/processes.ts

Execution:
- Accept user prompts via execute(args) method
- Configure API key via CredentialStore (no hardcoding)
- Use GoogleGenerativeAI client for API calls
- Implement error handling with AgentExecutionError and error context

Session Management:
- Implement SessionAdapter for analytics tracking
- Generate unique session IDs
- Set logger context with session/agent info
- Track model usage and token counts

Error Handling:
- AgentNotFoundError if plugin not registered
- AgentInstallationError for installation failures
- AgentExecutionError for runtime failures
- All errors include context: { agentName, sessionId, command }
- Use createErrorContext() and formatErrorForUser()

Security:
- API keys retrieved from CredentialStore
- No credentials in configuration files
- Input sanitized before logging
- Use sanitizeLogArgs() for all log statements

Testing Strategy:
- Unit tests: Mock @google/generative-ai client
- Unit tests: Test install/execute/isInstalled methods
- Integration tests: Full workflow with mocked responses
- Use vi.mock() and dynamic imports for proper mocking

## Review Process

### Step 1: Fetch Jira Ticket

```
Ticket EPMCDME-10900:
Summary: Add Gemini Agent Plugin Support

Acceptance Criteria:
- [ ] Users can install Gemini agent via 'codemie install gemini'
- [ ] Users can execute commands with 'codemie execute gemini'
- [ ] Session analytics captured for Gemini usage
- [ ] Secure API key management (no hardcoded credentials)
```

### Step 2: Load Applicable Guides

- ✅ `.codemie/guides/architecture/architecture.md` (Plugin architecture)
- ✅ `.codemie/guides/security/security-practices.md` (Credential management)
- ✅ `.codemie/guides/development/development-practices.md` (Error handling, logging)
- ✅ `.codemie/guides/testing/testing-patterns.md` (Testing strategy)

### Step 3: Review Against Jira Ticket

| Acceptance Criterion | Addressed in Spec | Status |
|---------------------|-------------------|--------|
| Install via 'codemie install gemini' | Installation section with commandExists/installGlobal | ✅ |
| Execute via 'codemie execute gemini' | Execution section with execute() method | ✅ |
| Session analytics captured | SessionAdapter for analytics tracking | ✅ |
| Secure API key management | CredentialStore usage, no hardcoding | ✅ |

### Step 4: Review Against Design Principles

#### Architecture Compliance ✅
- Plugin extends BaseAgentAdapter (correct inheritance)
- Registered in AgentRegistry (proper registration)
- CLI routes through registry (no layer skipping)
- No plugin-to-plugin dependencies

#### Security Compliance ✅
- API keys from CredentialStore (no hardcoding)
- Input sanitized before logging
- Uses sanitizeLogArgs() for all logs
- No credentials in config files

#### Error Handling Compliance ✅
- Specific error classes (AgentExecutionError, etc.)
- Error context included (sessionId, agentName, command)
- Uses createErrorContext() and formatErrorForUser()
- Proper error propagation

#### Testing Strategy ✅
- Clear unit/integration test separation
- Mocking strategy defined (vi.mock + dynamic imports)
- Critical paths identified
- External dependencies mocked

#### Logging Compliance ✅
- Uses logger from src/utils/logger.ts
- Session context set properly
- Data sanitization before logging
- Appropriate log levels

### Step 5: Clarity Assessment ✅
- Component responsibilities clear (GeminiPlugin, SessionAdapter)
- Interfaces well-defined (extends BaseAgentAdapter)
- Success criteria specified (acceptance criteria met)
- Focused on single feature (Gemini plugin only)
- Implementation details concrete and unambiguous
