# Admin Shell Session Tracking Implementation Plan

**Date**: 2026-02-06
**Status**: REVISED - Specialist Review Complete
**Approach**: Option B - MCP Event-Based Architecture
**Goal**: Universal session tracking for all admin shells

## 🔄 Revision Summary

This plan has been **REVISED** based on comprehensive specialist reviews (see `SESSION_TRACKING_PLAN_REVIEW_SUMMARY.md`).

### Critical Fixes Applied

1. ✅ **MCP Transport**: Changed from httpx HTTP to `mcp.ClientSession` (stdio transport)
2. ✅ **IPython Shutdown Hook**: Fixed incorrect `shutdown_hook` API usage (now uses `atexit` + threading)
3. ✅ **Async Event Loop**: Fixed `asyncio.run()` conflicts (checks for existing loop)
4. ✅ **Missing Imports**: Added `import logging` and other required imports
5. ✅ **Retry Logic**: Added exponential backoff retry with tenacity
6. ✅ **Circuit Breaker**: Added circuit breaker for health checks
7. ✅ **Input Sanitization**: Added input sanitization to prevent injection attacks
8. ✅ **Fire-and-Forget**: Session start emission no longer blocks shell startup

### Implementation Timeline (Revised)

| Phase | Original | Revised | Notes |
|-------|----------|---------|-------|
| Phase 0 | - | 3-4 hours | NEW: Security & Reliability Foundation |
| Phase 1 | 2-3 hours | 2-3 hours | Oneiric Layer (with fixes) |
| Phase 2 | 2-3 hours | 2-3 hours | Session-Buddy Layer (with auth) |
| Phase 3 | 1-2 hours | 1-2 hours | Component Integration |
| Phase 4 | 1-2 hours | 2-3 hours | Production Readiness (enhanced) |
| **Total** | **6-10 hours** | **10-15 hours** | **+4-5 hours** |

### Ready for Implementation

All critical issues identified by specialists have been incorporated into this revised plan. The architecture is sound and ready for development.

## Overview

This plan implements automatic session lifecycle tracking for all admin shells (Mahavishnu, Session-Buddy, Oneiric, and future components) using MCP events for loose coupling and maximum compatibility.

### Key Benefits

- **Universal**: Any component extending `AdminShell` gets automatic session tracking
- **Loose Coupling**: Components emit events via MCP, Session-Buddy receives and tracks
- **No Dependencies**: Components don't need direct Session-Buddy imports
- **Extensible**: New components work automatically without configuration
- **Production Ready**: Graceful degradation if Session-Buddy unavailable

```

**Key Corrections**:
1. ✅ Uses `mcp.ClientSession` instead of httpx
2. ✅ Uses stdio transport (not HTTP REST)
3. ✅ Adds missing `import logging`
4. ✅ Adds retry logic with tenacity
5. ✅ Adds circuit breaker for health checks
6. ✅ Sanitizes user input to prevent injection

## Component 5: Mahavishnu-Specific Overrides

**File**: `mahavishnu/shell/adapter.py` (MODIFY)

**Changes**: Override metadata methods

```python
class MahavishnuShell(AdminShell):
    # ... existing code ...

    def _get_component_version(self) -> str:
        """Get Mahavishnu version."""
        try:
            import importlib.metadata as importlib_metadata

            return importlib_metadata.version("mahavishnu")
        except Exception:
            return "unknown"

    def _get_adapters_info(self) -> list[str]:
        """Get enabled Mahavishnu adapters."""
        return list(self.app.adapters.keys()) if hasattr(self.app, "adapters") else []
```

---

## Implementation Phases

### Phase 1: Oneiric Layer (2-3 hours)

**Tasks**:
1. Create `oneiric/shell/session_tracker.py` with SessionEventEmitter
2. Modify `oneiric/shell/core.py`:
   - Add session_tracker instance
   - Add _notify_session_start() and _notify_session_end()
   - Add _get_component_version() and _get_adapters_info()
   - Register shutdown hook in start()

**Tests**:

---

### Phase 2: Session-Buddy MCP Layer (2-3 hours)

**Tasks**:
1. Create `session-buddy/mcp/session_tracker.py` with SessionTracker
2. Modify `session-buddy/mcp/tools.py` to register MCP tools
3. Ensure SessionLifecycleManager has create_session() and end_session() methods

**Tests**:
- Unit test for SessionTracker
- Integration test for MCP tool registration
- End-to-end test with mock admin shell

**Success Criteria**:
- MCP tools registered and accessible
- Session records created and updated correctly
- Session duration calculated automatically

---

### Phase 3: Component Integration (1-2 hours)

**Tasks**:
1. Update MahavishnuShell with version and adapters info
2. Update SessionBuddyShell with version info
3. Test both shells emit events correctly

**Tests**:
- Integration test for Mahavishnu shell
- Integration test for Session-Buddy shell
- Verify session records in database

**Success Criteria**:
- Both shells emit start/end events
- Session-Buddy tracks sessions correctly
- Shell banner shows session tracking status

---

### Phase 4: Testing & Documentation (1-2 hours)

**Tasks**:
1. Create comprehensive test suite
2. Update CLI shell guide with session tracking section
3. Add troubleshooting section

**Tests**:
- Unit tests (all components)
- Integration tests (all components)
- End-to-end test (real shell, real Session-Buddy)

**Success Criteria**:
- All tests pass
- Documentation complete
- User can verify session tracking works

---

## Testing Strategy

### Unit Tests

**SessionEventEmitter**:
- Test emit_session_start with valid event
- Test emit_session_end with valid session_id
- Test graceful degradation when Session-Buddy unavailable
- Test metadata formatting

**SessionTracker**:
- Test handle_session_start creates session
- Test handle_session_end updates session
- Test error handling for invalid data

**AdminShell**:
- Test _notify_session_start called on shell start
- Test _notify_session_end called on shell exit
- Test session_id stored correctly

### Integration Tests

**End-to-End Flow**:
1. Start Mahavishnu shell
2. Verify session_start event emitted
3. Verify session created in Session-Buddy
4. Execute commands in shell
5. Exit shell
6. Verify session_end event emitted
7. Verify session updated in Session-Buddy
8. Verify duration calculated correctly

### Manual Testing

```bash
# Terminal 1: Start Session-Buddy MCP
session-buddy mcp start

# Terminal 2: Start Mahavishnu shell
python -m mahavishnu shell

# Terminal 3: Check active sessions
session-buddy list-sessions --type admin_shell

# Terminal 2: Exit shell
exit()

# Terminal 3: Verify session ended
session-buddy show-session <session_id>
```

---

## Error Handling

### Graceful Degradation

**Scenario**: Session-Buddy MCP unavailable

**Behavior**:
- SessionEventEmitter logs warning
- AdminShell continues normally
- Shell remains functional
- Session tracking silently disabled

**Implementation**:
```python
if not self.available:
    logger.warning("Session-Buddy MCP unavailable - session not tracked")
    return None
```

### Event Emission Failure

**Scenario**: Network error during event emission

**Behavior**:
- Log error with details
- Continue execution (don't crash shell)
- Return None or False to indicate failure

**Implementation**:
```python
except Exception as e:
    logger.error(f"Failed to emit session start event: {e}")
    return None
```

### Session Record Creation Failure

**Scenario**: Session-Buddy database error

**Behavior**:
- Return error response to component
- Component logs error but continues
- Shell remains functional

**Implementation**:
```python
except Exception as e:
    ctx.error(f"Failed to track session start: {e}")
    return {"session_id": None, "status": "error", "error": str(e)}
```

---

## Documentation Updates

### Files to Update

1. **`docs/CLI_SHELL_GUIDE.md`**
   - Add "Session Tracking" section
   - Explain automatic integration
   - Show verification steps

   - Document session tracking tools
   - Provide event format specification

4. **`CHANGELOG.md`**
   - Add entry for session tracking feature
   - List all component versions

---

## Alternative Approaches Considered

### Option A: Direct Lifecycle Hooks (Rejected)
**Pros**:
- Tightly coupled, direct control

**Cons**:
- Requires Session-Buddy dependency in all components
- Breaks if Session-Buddy not installed
- Not extensible to new components

### Option C: Polling-Based (Rejected)
**Pros**:
- Simple to implement

**Cons**:
- Resource intensive
- Delayed detection
- Not event-driven

### Option B: MCP Events (Selected)
**Pros**:
- Loose coupling
- Universal compatibility
- Extensible
- Production-ready

**Cons**:
- Requires Session-Buddy MCP running
- Minimal (acceptable)

---

## Open Questions

1. **Session-Buddy version requirement**: Should we require minimum Session-Buddy version for session tracking?
2. **Event format**: Should we use JSON Schema for event validation?
3. **Authentication**: Should session events be authenticated?
4. **Rate limiting**: Should we rate limit event emission?

---

## Next Steps

1. ✅ Draft implementation plan (this document)
2. ⏳ **Have plan reviewed by specialists**
   - Architecture specialist
   - MCP specialist
   - Session-Buddy specialist
3. ⏳ **Implement Phase 1** (Oneiric layer)
4. ⏳ **Implement Phase 2** (Session-Buddy layer)
5. ⏳ **Implement Phase 3** (Component integration)
6. ⏳ **Implement Phase 4** (Testing & documentation)
7. ⏳ **Rollout and release**

---

## Summary

This plan implements universal session tracking for all admin shells using MCP events for loose coupling and maximum compatibility. Any component extending `AdminShell` gets automatic session tracking without additional code, making it future-proof for new components.

The implementation is production-ready with graceful degradation, comprehensive error handling, and extensive testing coverage.
