# The Engineer Agent
|
|
|
|
Employee #1 of APEX OS
|
|
|
|
## Purpose
|
|
The Engineer is the first autonomous AI employee. It builds software, manages infrastructure, and creates future AI employees.
|
|
|
|
## Architecture
|
|
- **Brain:** Letta agent (agent-4e3c3862-d0ba-47c6-8f2e-74249e1cfe4a) with GPT-4o via LiteLLM
|
|
- **Execution:** n8n workflows (Engineer-Core: hGB9I4OKXyUOrBdX)
|
|
- **Knowledge:** mem0 (pgvector) + Letta archival memory
|
|
- **Code:** Gitea repositories (engineer user)
|
|
- **Deployment:** Docker via Socket Proxy (write-enabled)
|
|
- **Tracking:** PostgreSQL apex DB (projects, tasks, deployments, engineer_decisions)
|
|
|
|
## Capabilities
|
|
- ✅ Software planning and task decomposition
|
|
- ✅ Code generation (GPT-4o, Claude 3.5 Sonnet via LiteLLM)
|
|
- ✅ Git operations (Gitea API — create repos, commit files, manage issues)
|
|
- ✅ Docker container deployment (via socket proxy with POST/EXEC/START/STOP)
|
|
- ✅ REST API creation and management
|
|
- ✅ n8n workflow creation and management (via API key)
|
|
- ✅ Node.js test execution (via n8n Execute Command)
|
|
- ✅ Log analysis and monitoring (Loki, Grafana, Prometheus)
|
|
- ✅ Documentation generation
|
|
- ✅ Creating other AI employees (via Letta multi-agent API)
|
|
- ✅ Shared knowledge queries (mem0 pgvector semantic search)
|
|
- ✅ Long-term memory (Letta archival memory)
|
|

## Usage
|
|
|
|
### Via n8n Webhook
|
|
```bash
|
|
curl -X POST https://n8n.apex.unstuck-path.com/webhook/engineer/task \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"task": "description of what to build", "context": "additional context"}'
|
|
```
|
|
|
|
### Via Letta API (Direct)
|
|
```bash
|
|
curl -X POST http://letta:8283/v1/agents/agent-4e3c3862-d0ba-47c6-8f2e-74249e1cfe4a/messages \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"messages": [{"role": "user", "content": "Your task here"}]}'
|
|
```
|
|
|
|
## Decision-Making Process
|
|
1. Receive task via webhook or direct API call
|
|
2. Letta agent (GPT-4o) analyzes and plans
|
|
3. Breaks into subtasks stored in `tasks` table
|
|
4. Executes each subtask via appropriate API
|
|
5. Logs decisions in `engineer_decisions` table
|
|
6. Updates project status in `projects` table
|
|
7. Stores lessons learned in archival memory
|
|
|
|
## Project Tracking
|
|
All projects are tracked in the `apex` database:
|
|
- `projects` — Project metadata and status
|
|
- `tasks` — Individual task breakdown
|
|
- `deployments` — Container deployment history
|
|
- `engineer_decisions` — Decision rationale log
|
|
