ras-commander: Skill for Claude Code

Organizing eBFE Models

Purpose

When the user asks to organize eBFE or BLE downloads, use this skill to transform downloaded FEMA eBFE/BLE study area files into a standardized 4-folder structure, regardless of the original archive organization patterns.

Standardized Output Structure

Every organized eBFE study area should have this structure:

{StudyAreaName}_{HUC8}/
├── HMS Model/              # HEC-HMS hydrologic models
│   ├── {ProjectName}.hms
│   ├── {ProjectName}.basin
│   ├── *.dss
│   └── ... (all HMS-related files)
├── RAS Model/              # HEC-RAS hydraulic models
│   ├── {Model1}/
│   │   ├── {Model1}.prj
│   │   ├── {Model1}.g##
│   │   ├── {Model1}.p##
│   │   └── ... (all RAS project files)
│   └── {Model2}/...
├── Spatial Data/           # GIS, terrain, geodatabases
│   ├── Terrain/
│   ├── *.tif, *.hdf
│   ├── *.gdb/
│   └── ... (all spatial data)
└── Documentation/          # Reports, metadata, inventories
    ├── *.pdf
    ├── *.xlsx (inventories)
    ├── *_metadata.xml
    └── ... (all documentation)

Input Patterns

Handle these downloaded archive patterns:

Pattern 1: Multiple 1D models in variable wrapper folders (80-200 MB) Pattern 2: ModelURLs.txt links file (1 KB) Pattern 3: Single 2D model in nested zip (5-15 GB) Pattern 4: Compound HMS + RAS in nested zips (8+ GB)

See feature_dev_notes/eBFE_Integration/RESEARCH_FINDINGS.md for complete pattern documentation.

File Classification Rules

HMS Model/ Folder

Include files with these extensions or patterns:

• .hms - HEC-HMS project
• .basin - Basin model file
• .met - Meteorology file
• .control - Control specifications
• .run - Run configuration
• .results - HMS results
• .dss in Hydrology/ path
• .log, .out in HMS folders

Path indicators: Hydrology/, HMS/

RAS Model/ Folder

Include files with these extensions or patterns:

• .prj - HEC-RAS project (validate: contains "Proj Title=", "Geom File=")
• .g## - Geometry file
• .p## - Plan file
• .f## - Flow file
• .u## - Unsteady flow file
• .c## - Sediment file
• .b## - Bridge/culvert file
• .bco## - Boundary condition override
• .IC.O## - Initial conditions override
• .x## - Cross section index
• .rasmap - RAS Mapper project
• .dsc - DSS catalog (if in RAS folder)
• .dss (if in RAS folder, not HMS folder)
