+# visdet - Repository Guidelines
+
+This is a minimal version of MMDetection, supporting only Swin Mask R-CNN for object detection and instance segmentation.
+
+## Repository Structure
+
+### Documentation Files
+
+- **README.md** - Main project documentation (keep at root)
+- **AGENTS.md** - This file, repository-wide guidelines (keep at root)
+- **Other capitalised markdown files** - Should be written to the `scratch_pads/` directory
+
+The `scratch_pads/` directory is intended for experimental documentation, planning documents, and other markdown files that are not part of the core repository documentation. This keeps the root directory clean and organized.
+
+## Key Principles
+
+1. **Single Model Focus**: Only support Swin Transformer + Mask R-CNN
+2. **COCO Format**: Only support COCO-style datasets
+3. **Essential Components**: Keep only what's needed for this specific model
+4. **Absolute Imports**: Always use absolute imports (e.g., `from visdet.engine import X`) instead of relative imports (e.g., `from .engine import X`) to avoid circular import issues
+
+## What to Keep
+
+### Models
+
+- **Backbone**: SwinTransformer only
+- **Neck**: FPN only
+- **Head**: RPNHead, StandardRoIHead (with bbox and mask branches)
+- **Detector**: MaskRCNN (two-stage detector)
+
+### Data
+
+- COCO dataset format support
+- Essential data transforms for training/inference
+- DetDataPreprocessor
+
+### Evaluation
+
+- COCO metrics for object detection and instance segmentation
+
+## What to Remove
+
+- All other backbones (ResNet, RegNet, etc.)
+- All other detectors (YOLO, RetinaNet, DETR, etc.)
+- All other necks (PAFPN, NAS-FPN, etc.)
+- Video/tracking components
+- 3D detection components
+- Panoptic segmentation
+- All other dataset formats
+
+## Dependencies
+
+- Training infrastructure (visengine)
+- Image operations (viscv)
+- pycocotools for COCO evaluation
