# 🔧 REMAINING WORK - EXACT ACTION PLAN

**Current Status**: 75% complete
**Time to 100%**: ~6 hours
**Critical Blockers**: 3 (fixable in ~2 hours)

## 🚨 CRITICAL BLOCKER #1: Fix Package __init__.py

**File**: `src/atoms_mcp/__init__.py`
**Problem**: Still loading OLD code that doesn't exist
**Impact**: Cannot import anything from the package
**Fix Time**: 15 minutes

### Current (BROKEN):
```python
"""
Atoms MCP Server Package

Model Context Protocol server for Atoms workspace management.
"""

from .core.mcp_server import AtomsServer  # ← THIS IS BROKEN

__all__ = ["AtomsServer"]
```

### Required Fix (Option 1 - Recommended):
```python
"""
Atoms MCP Server with Hexagonal Architecture

Clean separation of concerns using hexagonal architecture pattern.
Imports exposed here are part of the public API.
"""

__version__ = "2.0.0"

# Public API exports from each layer
from .domain.models import Entity, Workspace, ProjectEntity, TaskEntity
from .domain.services import EntityService, RelationshipService
from .application.commands import CreateEntityCommand, UpdateEntityCommand
from .application.queries import GetEntityQuery, ListEntitiesQuery
from .infrastructure.config import get_settings
from .infrastructure.logging import get_logger
from .adapters.primary.mcp import create_mcp_server
from .adapters.primary.cli import create_cli_app

__all__ = [
    # Domain
    "Entity",
    "Workspace",
    "ProjectEntity",
    "TaskEntity",
    "EntityService",
    "RelationshipService",
    # Application
    "CreateEntityCommand",
    "UpdateEntityCommand",
    "GetEntityQuery",
    "ListEntitiesQuery",
    # Infrastructure
    "get_settings",
    "get_logger",
    # Adapters
    "create_mcp_server",
    "create_cli_app",
]
```

### How to Apply:
```bash
# Option A: Use sed to replace the import
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod
cp src/atoms_mcp/__init__.py src/atoms_mcp/__init__.py.backup
# Then edit the file with the content above

# Option B: Minimal fix (if Option 1 has errors)
sed -i '' 's/from .core.mcp_server import AtomsServer/__version__ = "2.0.0"/' src/atoms_mcp/__init__.py
sed -i '' 's/__all__ = \["AtomsServer"\]/__all__ = []/' src/atoms_mcp/__init__.py
```

### Verify:
```bash
python3 -c "import sys; sys.path.insert(0, 'atoms-mcp-prod'); from src.atoms_mcp import __version__; print(f'✓ Import works, version: {__version__}')"
```

## 🚨 CRITICAL BLOCKER #2: Delete Old Code Directory

**Directory**: `src/atoms_mcp/core/`
**Problem**: Contains old, broken implementations that conflict with new architecture
**Impact**: Confusion about which code to use, potential import conflicts
**Fix Time**: 30 minutes

### What's in there:
```
src/atoms_mcp/core/
├── __init__.py
├── mcp_server.py          ← OLD server (different from new adapters/primary/mcp/)
├── models/
│   ├── __init__.py
│   ├── base.py
│   ├── enums.py
│   └── ...
└── ...
```

### How to Fix:
```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod

# Option A: Delete it
rm -rf src/atoms_mcp/core/

# Option B: Archive it for reference (safer)
mv src/atoms_mcp/core/ src/atoms_mcp/core_legacy_v1_backup/
```

### Verify No References:
```bash
# Check if anything imports from core/
grep -r "from .core" src/atoms_mcp/
grep -r "from atoms_mcp.core" src/atoms_mcp/

# Should return: (nothing)
```

## 🚨 CRITICAL BLOCKER #3: Remove Old CLI/Config Files

**Files to Remove**:
- `atoms_cli.py` (old CLI)
- `atoms_cli_enhanced.py` (old enhanced CLI)
- `atoms_server.py` (old server script)
- `atoms` (old executable script)
- `config/` directory (8 old config files)
- `settings/` directory (5 old settings files)

**Problem**: Duplicate implementations, confusion about which to use
**Impact**: Repository bloat, unclear architecture
**Fix Time**: 1 hour total

### How to Find Them:
```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod

# Find all the old files
find . -maxdepth 1 -name "atoms*" -type f
find . -type d -name "config" -o -type d -name "settings"
```

### How to Remove:
```bash
# These files no longer exist because they were in the old repo state
# The new refactored code has replaced them:
# - atoms_cli.py          → src/atoms_mcp/adapters/primary/cli/
# - atoms_cli_enhanced.py → src/atoms_mcp/adapters/primary/cli/
# - config/               → src/atoms_mcp/infrastructure/config/
# - settings/             → src/atoms_mcp/infrastructure/config/

# Check if they still exist in repo
ls -la atoms_cli.py 2>&1  # File not found = good
ls -la config/ 2>&1       # Directory not found = good
```

### Verify Removal:
```bash
# Should show no .py files in root directory matching old names
ls *.py | grep -E "atoms|config|settings"
# Should return: (nothing)
```

## ✅ VERIFICATION STEPS (After Fixes Above)

### Step 1: Test Basic Imports (15 minutes)
```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod

# Test domain layer
python3 << 'PYTHON'
import sys
sys.path.insert(0, 'src')
from atoms_mcp.domain.models import Entity
from atoms_mcp.domain.services import EntityService
print("✓ Domain layer imports work")
PYTHON

# Test application layer
python3 << 'PYTHON'
import sys
sys.path.insert(0, 'src')
from atoms_mcp.application.commands import CreateEntityCommand
from atoms_mcp.application.queries import GetEntityQuery
print("✓ Application layer imports work")
PYTHON

# Test infrastructure layer
python3 << 'PYTHON'
import sys
sys.path.insert(0, 'src')
from atoms_mcp.infrastructure.config import get_settings
from atoms_mcp.infrastructure.logging import get_logger
print("✓ Infrastructure layer imports work")
PYTHON

# Test adapters
python3 << 'PYTHON'
import sys
sys.path.insert(0, 'src')
from atoms_mcp.adapters.primary.cli import create_cli_app
from atoms_mcp.adapters.secondary.supabase import SupabaseRepository
print("✓ Adapters imports work")
PYTHON
```

### Step 2: Run Type Checking (30 minutes)
```bash
# Type check domain layer
python3 -m py_compile src/atoms_mcp/domain/**/*.py

# Type check application layer
python3 -m py_compile src/atoms_mcp/application/**/*.py

# Type check infrastructure layer
python3 -m py_compile src/atoms_mcp/infrastructure/**/*.py

# Type check adapters
python3 -m py_compile src/atoms_mcp/adapters/**/*.py

# All should succeed with no output
```

### Step 3: Run Lint Check (15 minutes)
```bash
# If ruff is available
ruff check src/atoms_mcp/

# If pylint is available
pylint --disable=all --enable=syntax-error src/atoms_mcp/
```

### Step 4: Run Unit Tests (1-2 hours)
```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod

# First, just collect tests (no execution)
pytest tests/unit_refactor/ --collect-only -q

# Then run them
pytest tests/unit_refactor/ -v

# With coverage
pytest tests/unit_refactor/ --cov=src/atoms_mcp --cov-report=html
```

## 🚨 LIKELY ISSUES & FIXES

### Issue 1: ImportError after fixing __init__.py
```
ModuleNotFoundError: No module named 'atoms_mcp.domain'
```
**Cause**: Python path not set correctly
**Fix**:
```bash
export PYTHONPATH="${PYTHONPATH}:/Users/kooshapari/temp-PRODVERCEL/485/kush/atoms-mcp-prod/src"
python3 test_imports.py
```

### Issue 2: Circular imports in application layer
```
ImportError: cannot import name 'X' from partially initialized module 'atoms_mcp.application'
```
**Cause**: application imports from adapters which imports from application
**Fix**: Check all imports are clean (domain imports nothing, app imports domain, adapters import app)

### Issue 3: Tests fail due to missing mocks
```
AttributeError: 'MockRepository' object has no attribute 'save'
```
**Cause**: Mock classes not complete
**Fix**: Check conftest.py has complete mock implementations

### Issue 4: Settings not loading
```
ValidationError: settings validation failed
```
**Cause**: Required environment variables not set
**Fix**:
```bash
export SUPABASE_URL="http://localhost:54321"
export SUPABASE_KEY="test-key"
export VERTEX_AI_PROJECT="test-project"
```

## 📞 DECISION POINTS

### Q1: Should we delete or archive core/?
**Answer**: DELETE - It's legacy code, causes confusion, wastes space
**Confidence**: High

### Q2: Should we keep old CLI files as deprecated?
**Answer**: DELETE - We have new CLI in adapters/primary/cli/
**Confidence**: High

### Q3: What if tests still fail after all fixes?
**Answer**:
- Run with `-vv` to see full output
- Check which test fails first
- Look at error message for root cause
- Fix one at a time

### Q4: Should we update documentation after fixes?
**Answer**: YES - Update START_HERE_REFACTOR_INDEX.md with actual status
**Confidence**: High
