# Project Process Tracking System

## Overview

Autocoder v2 now automatically tracks and cleans up processes spawned by projects being built, preventing zombie process accumulation.

**What gets tracked:**
- Dev servers (npm run dev, vite, flask run, etc.)
- Databases (postgres, mysql, mongodb, redis)
- Build processes (npm build, webpack, etc.)
- Other processes started during development

## How It Works

### Automatic Cleanup

**Feature transitions (automatic):**
When the agent calls `feature_mark_passing`, the system:
1. ✅ Kills dev servers and build processes
2. ✅ Keeps databases running (they persist across features)
3. ✅ Logs cleanup results

**Session end (automatic):**
When the agent finishes or is stopped:
- All project processes are killed (including databases)
- Process counts are logged by category

**UI stop button:**
When you stop the agent via the UI:
- Agent process tree is killed (agent + MCP servers)
- All project processes are killed
- Everything is cleaned up automatically

### Manual Control (MCP Tools)

The agent has access to these MCP tools:

```python
# Check what's running
project_processes_status()

# Kill dev servers
project_processes_cleanup(category="dev_server")

# Kill everything (including databases)
project_processes_cleanup(category="all")

# Register a background process (optional)
project_process_register(pid=12345, command="npm run dev")
```

### Categories

Processes are automatically categorized by pattern matching:

| Category | Examples |
|----------|----------|
| `dev_server` | npm run dev, vite, flask run, uvicorn, next dev |
| `database` | postgres, mysqld, mongod, redis-server |
| `build` | npm run build, webpack, vite build |
| `other` | Everything else |

## Implementation Details

### Core Components

**1. ProjectProcessTracker** (`server/services/project_process_tracker.py`)
- Tracks PIDs and categorizes processes
- Stores state in `.project_processes.json` per project
- Provides cleanup methods by category

**2. Feature MCP Server** (`mcp_server/feature_mcp.py`)
- Added cleanup hook to `feature_mark_passing`
- New tools: `project_processes_status`, `project_processes_cleanup`, `project_process_register`

**3. Agent Integration** (`agent.py`)
- Cleanup on session end

**4. Process Manager** (`server/services/process_manager.py`)
- Cleanup when agent is stopped via UI

**5. System API** (`server/routers/system.py`)
- REST endpoints for viewing/cleaning project processes
- `/api/system/project-processes/{project_name}` - GET status
- `/api/system/project-processes/{project_name}/cleanup` - POST cleanup
- `/api/system/project-processes/cleanup-all` - POST cleanup all projects

**6. Coding Prompt** (`.claude/templates/coding_prompt.template.md`)
- Added STEP 2.5 explaining automatic process management
- Instructions for manual tools when needed

## Usage Examples

### For Agents (in prompts)

The system is mostly automatic. Agents just need to know:

```markdown
Automatic cleanup happens when you call feature_mark_passing.
Databases stay running, dev servers get killed.

If you need to manually check or cleanup:
- Use project_processes_status to see what's running
- Use project_processes_cleanup with category="dev_server" to kill dev servers
```

### For API/UI

```bash
# Get process status for a project
GET /api/system/project-processes/my-project

# Cleanup dev servers for a project
POST /api/system/project-processes/my-project/cleanup?category=dev_server

# Cleanup everything for all projects
POST /api/system/project-processes/cleanup-all
```

### For Direct Python

```python
from server.services.project_process_tracker import get_tracker
from pathlib import Path

tracker = get_tracker(Path("/path/to/project"))

# Check status
status = tracker.get_status()
print(status["total_processes"])

# Cleanup between features (smart - keeps databases)
tracker.cleanup_between_features()

# Cleanup everything
tracker.cleanup_all()
```

## Testing

To test the system:

1. Start a project with dev server:
```bash
cd test-project
npm run dev &
DEV_PID=$!
```

2. Check tracking (via MCP or API):
```python
# Should show the dev server
project_processes_status()
```

3. Mark a feature passing:
```python
# Dev server should be killed automatically
feature_mark_passing(feature_id=1)
```

4. Verify cleanup:
```bash
# Process should be gone
ps -p $DEV_PID
```

## State Files

Each project gets a state file: `{project_dir}/.project_processes.json`

Example:
```json
{
  "processes": [
    {
      "pid": 12345,
      "command": "npm run dev",
      "category": "dev_server",
      "started_at": 1704067200.0
    }
  ]
}
```

State persists across agent restarts. Dead processes are removed on load.

## Design Decisions

**Why kill dev servers between features?**
- Prevents port conflicts
- Forces clean restart for next feature
- Reduces memory/CPU usage

**Why keep databases running?**
- Data should persist across features
- Expensive to restart
- No port conflicts (one instance per project)

**Why automatic cleanup on feature_mark_passing?**
- Agent doesn't have to remember to cleanup
- Consistent cleanup behavior
- Reduces prompt complexity

**Why separate from AgentProcessManager?**
- Different lifecycle (agent vs project processes)
- Different cleanup rules
- Clear separation of concerns

## Future Enhancements

Potential improvements:

1. **Smart detection**: Parse bash output to auto-register processes
2. **Port tracking**: Track which ports are in use
3. **Restart detection**: Detect when agent restarts same dev server
4. **Resource monitoring**: Track CPU/memory per process
5. **UI integration**: Show process status in the web UI

## Troubleshooting

**Processes not being tracked?**
- Check `.project_processes.json` exists
- Verify process patterns in `project_process_tracker.py`
- Use `project_process_register` to manually register

**Cleanup not working?**
- Check process is still alive (`psutil.pid_exists`)
- Verify process wasn't already killed
- Check logs for cleanup errors

**State file corruption?**
- Delete `.project_processes.json` to reset
- Tracker will rebuild from currently running processes

Excellent! Now let me create a quick summary for the user.


## ✅ Project Process Tracking Complete!

I've successfully implemented comprehensive process tracking for v2. Here's what was built:

### What It Does

**Automatically tracks and kills processes spawned by projects being built:**
- ✅ Dev servers (npm, vite, flask, etc.)
- ✅ Databases (postgres, mysql, mongodb, redis)
- ✅ Build processes (webpack, npm build, etc.)

### Automatic Cleanup Points

1. **Between features** - When agent calls `feature_mark_passing`:
   - Kills dev servers and builds
   - Keeps databases running

2. **Session end** - When agent finishes:
   - Kills everything (including databases)

3. **UI stop button** - When you stop the agent:
   - Kills agent + MCP servers + all project processes

### Components Created

| File | Purpose |
|------|---------|
| `server/services/project_process_tracker.py` | Core tracking class |
| `mcp_server/feature_mcp.py` | Added 3 new MCP tools + cleanup hooks |
| `client.py` | Registered new MCP tools |
| `.claude/templates/coding_prompt.template.md` | Added STEP 2.5 instructions |
| `agent.py` | Session-end cleanup |
| `server/services/process_manager.py` | UI stop cleanup |
| `server/routers/system.py` | REST API endpoints |
| `PROJECT_PROCESS_TRACKING.md` | Complete documentation |

### New MCP Tools for Agents

```python
project_processes_status()              # Check what's running
project_processes_cleanup(category)     # Manual cleanup
project_process_register(pid, command)  # Register process
```

### API Endpoints (for UI integration later)

```bash
GET  /api/system/project-processes/{project}
POST /api/system/project-processes/{project}/cleanup
POST /api/system/project-processes/cleanup-all
```

### How It Works

1. Processes are categorized automatically by command patterns
2. State stored in `{project}/.project_processes.json`
3. Dead processes cleaned up on load
4. Smart cleanup: keeps databases, kills dev servers

**No zombie processes anymore!** 🎉
