# Start Pixel Detective

Use this skill to run Pixel Detective locally with the right subset of services.

## Quickstart
- Full stack: `powershell -ExecutionPolicy Bypass -File skills\\start-pixel-detective\\scripts\\start_pixel_detective.ps1 -Mode full`
- Backend only (+ optional GPU UMAP): `powershell -ExecutionPolicy Bypass -File skills\\start-pixel-detective\\scripts\\start_pixel_detective.ps1 -Mode backend -UseGpuUmap`

## Workflow

1. Confirm repo root
- Require `frontend/package.json` and `start_pixel_detective.ps1`.
- If missing, stop and ask for the correct working directory.

2. Decide the requested mode
- full: all services plus frontend
- backend: Qdrant + ML + ingestion (optional UMAP)
- services: just Docker services (Qdrant and optional GPU UMAP)
- frontend: only Next.js dev server
- status: report what is running
- stop: stop Docker services and list any remaining processes

3. Docker preflight
- Check Docker CLI and Docker Compose:
  - `docker version`
  - `docker compose version`
- If Docker is installed but not running, say so and stop.

4. Start sequence
- full: run `.\start_pixel_detective.ps1`
- backend:
  - `docker compose up -d qdrant_db`
  - optional GPU UMAP: `docker compose -f backend/gpu_umap_service/docker-compose.dev.yml up -d --build`
  - start ML service: `uvicorn backend.ml_inference_fastapi_app.main:app --port 8001 --reload`
  - start ingestion: `uvicorn backend.ingestion_orchestration_fastapi_app.main:app --port 8002 --reload`
- services:
  - `docker compose up -d qdrant_db`
  - optional GPU UMAP (same command as above)
- frontend:
  - `cd frontend` then `npm run dev`

When launching uvicorn or npm, use new terminal windows so the main session stays responsive.

5. Status checks
- `docker compose ps`
- The script prints a port readiness summary (6333/8001/8002/8003/3000).
- Report URLs:
  - http://localhost:3000
  - http://localhost:8002/docs
  - http://localhost:8001/docs
  - http://localhost:8003/docs
  - http://localhost:6333/dashboard

6. Stop sequence
- `docker compose down`
- The script attempts to close uvicorn and npm windows tied to this repo.

## Notes
- The GPU UMAP service can fail without blocking the rest. Treat it as optional.
- Use existing startup scripts whenever possible to stay aligned with repo behavior.
- Qdrant is the only required Docker service for Pixel Detective; ML and ingestion run on the host.
- If port 3000 is already in use, Next.js will choose 3001 or another port; report the actual port from the terminal output.
- If the ML or ingestion uvicorn process exits immediately, check for missing Python dependencies or a virtualenv not being activated.

## Script
- Run: `powershell -ExecutionPolicy Bypass -File skills\\start-pixel-detective\\scripts\\start_pixel_detective.ps1 -Mode full`
- Backend only: `-Mode backend -UseGpuUmap`
- Frontend + open page: `-Mode frontend -Open -Page /search`
- Note: `-Open` is required to open a browser; `-Page` alone will not open anything.
