Pixel Detective Exports

Generate standalone exports (no UI) and manage collections for Pixel Detective.

Requirements

• Ingestion API running on http://localhost:8002
• Qdrant running (Docker)
• GPU UMAP service on http://localhost:8003 for HDBSCAN clustering
• Optional (for visuals): matplotlib
• Optional (for PDF output): weasyprint (preferred) or playwright

Quickstart

• UMAP + HDBSCAN JSON/CSV/SVG: python skills/pixel-detective-exports/scripts/export_umap_hdbscan.py --collection <name>
• Cluster report PDF/HTML (all collections): python skills/pixel-detective-exports/scripts/export_umap_pdf.py --sample-size 500

Exports

UMAP + HDBSCAN export (standalone)

• Script: python skills/pixel-detective-exports/scripts/export_umap_hdbscan.py
• Output default: exports/pixel-detective/umap/umap_hdbscan_<collection>.json|csv|svg
• Example:
  • python skills/pixel-detective-exports/scripts/export_umap_hdbscan.py --collection my_collection --sample-size 2000
  • Color controls: --color-map tab20 --point-size 18 --outlier-size 12 --outlier-color #94a3b8

UMAP PDF report (all collections)

• Script: python skills/pixel-detective-exports/scripts/export_umap_pdf.py
• Output default: exports/pixel-detective/umap/umap_cluster_report.pdf
• Example:
  • python skills/pixel-detective-exports/scripts/export_umap_pdf.py --sample-size 500 --title "Pixel Detective UMAP Clusters"

Collection management

Manage collections via API (Qdrant in Docker)

• Script: python skills/pixel-detective-exports/scripts/manage_collections.py
• Examples:
  • List: python skills/pixel-detective-exports/scripts/manage_collections.py --action list
  • Info: python skills/pixel-detective-exports/scripts/manage_collections.py --action info --collection my_collection
  • Create: python skills/pixel-detective-exports/scripts/manage_collections.py --action create --collection my_collection --vector-size 512 --distance Cosine
  • Select: python skills/pixel-detective-exports/scripts/manage_collections.py --action select --collection my_collection
  • Delete: python skills/pixel-detective-exports/scripts/manage_collections.py --action delete --collection my_collection
  • Merge: python skills/pixel-detective-exports/scripts/manage_collections.py --action merge --dest merged_collection --sources a,b,c
  • Qdrant fallback listing: python skills/pixel-detective-exports/scripts/manage_collections.py --action list --qdrant http://localhost:6333

Notes

• HDBSCAN clustering is performed by the GPU UMAP service; the ingestion service does not offer HDBSCAN.
• Collection operations go through the ingestion API, which talks to Qdrant in Docker.
• Use the start skill to bring up services:
  • powershell -ExecutionPolicy Bypass -File skills\\start-pixel-detective\\scripts\\start_pixel_detective.ps1 -Mode backend -UseGpuUmap
