DeepResearch Agent v2.0 - Project Status

Last Updated: 2026-02-09 Phase: Day 1 - Foundation Complete ✅

Completed Tasks

✅ Day 1: Project Scaffolding + Architecture (100%)

Morning Session

  • Initialize monorepo structure with npm workspaces

  • Validate LikeC4 configuration

Afternoon Session

  • Initialize FastAPI backend project structure
  • Create requirements.txt with all dependencies
  • Implement /health endpoint
  • Configure settings management (pydantic-settings)
  • Create Docker Compose configuration (PostgreSQL + Backend)
  • Create Dockerfiles (Backend + Sandbox)
  • Create setup scripts (Bash + PowerShell)
  • Write comprehensive documentation (README + QUICKSTART)
  • Add basic tests for FastAPI

Next Steps (Day 2)

Morning (4 hours)

  • PostgreSQL event store schema design
  • Initialize Alembic migrations
  • Create projection tables (research_projects, findings)

Afternoon (4 hours)

  • Implement EventStore class (append, get_events)
  • Define event types (ResearchCreated, PlanGenerated, etc.)
  • Write event store unit tests
  • Test event reconstruction

Technology Stack

Component Technology Status
Architecture LikeC4 1.48.0 ✅ Configured
Backend FastAPI 0.109 + Python 3.11 ✅ Scaffolded
Database PostgreSQL 16 ✅ Docker ready
Agent Framework LangGraph 0.0.26 ⏸️ Day 3
Research GPT Researcher 0.7.5 ⏸️ Day 4
Sandbox Docker SDK 7.0 ⏸️ Day 5
Frontend Electron + React ⏸️ Day 5

Current Capabilities

✅ What Works Now:

  • Project structure is set up
  • Architecture model validates
  • FastAPI application runs locally
  • Health check endpoint works
  • Docker Compose configuration ready
  • Comprehensive documentation

⏸️ Not Yet Implemented:

  • Event sourcing
  • LangGraph orchestrator
  • 5-agent workflow
  • Docker sandbox runner
  • Desktop application
  • Real research functionality

How to Test Current Setup

1. View Architecture

npm run likec4
# Visit: http://localhost:4040

2. Start Database

docker-compose up -d postgres

3. Run Backend (Local)

cd src/backend
python -m venv .venv
.venv\Scripts\activate  # Windows
source .venv/bin/activate  # Linux/Mac
pip install -r requirements.txt
python main.py

4. Test API

curl http://localhost:8000/health
curl http://localhost:8000/docs

5. Run Tests

cd src/backend
pytest

Success Metrics (Day 1)

Metric Target Actual Status
Monorepo setup ✅ ✅ Done
LikeC4 working ✅ ✅ Done
FastAPI running ✅ ✅ Done
Docker Compose ✅ ✅ Done
Documentation ✅ ✅ Done
Basic tests ✅ ✅ Done

Known Issues

  1. LikeC4 Node Version Warning

    • Current: Node 22.16.0
    • Required: Node 22.21.1+
    • Impact: Non-blocking warning
    • Fix: Upgrade Node.js (optional)

  2. Docker Socket Mount (Windows)

    • Windows Docker Desktop uses named pipes
    • May need adjustment for sandbox functionality
    • Will test in Day 5

  3. Simplified Architecture Model

    • Current model is minimal for MVP
    • Detailed components/services to be added incrementally
    • Full model documented in plan

Timeline

  • ✅ Day 1 (2026-02-09): Foundation + Architecture
  • 📅 Day 2 (2026-02-10): Event Sourcing + PostgreSQL
  • 📅 Day 3 (2026-02-11): LangGraph Orchestrator
  • 📅 Day 4 (2026-02-12): Agent Implementation
  • 📅 Day 5 (2026-02-13): Docker Sandbox + Electron
  • 📅 Week 2: Integration, Testing, Documentation

Team Notes

For Next Session:

  1. Ensure Docker Desktop is running
  2. Create .env file from .env.example
  3. Start with Day 2 tasks (Event Sourcing)
  4. Reference QUICKSTART.md for setup help

Critical Path:

  • Event Store → Agents → Sandbox → Desktop UI
  • Each component blocks the next
  • Mock mode allows independent testing
