Network QA of an existing INP (disconnected nodes, missing outfalls, adverse or zero slopes) is one call, network_qa, so call it first. Also builds, validates and routes SWMM pipe-network models from raw municipal shapefiles or structured GIS/CAD exports. Use when handling junctions, conduits, outfalls, xsections, network field-mapping configs, or wiring subcatchments to upstream nodes. Requires real pipe data as SHP / GeoJSON / CSV — native CAD (DXF/DWG) is not parsed and must first be…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SWMM Network (pipe-system layer) Part of [Agentic SWMM](https://github.com/Zhonghao1995/agentic-swmm-workflow) — install the project first for the executable toolchain (aiswmm CLI, SWMM solver, MCP servers). ## What this skill provides - A stable JSON schema for SWMM drainage-network structure. - Two complementary import paths: - **Raw municipal shapefile path** (`prepare_storm_inputs` → `infer_outfall` → `reorient_pipes` → `import_city_network` → `qa`) for typical city storm-pipe + manhole layers that arrive as bare LineString shapefiles. - **Structured asset-DB path** (`import_city_network` directly, or `import_network` for a fully field-mapped GeoJSON/CSV) when the source already contains explicit from/to nodes, inverts, and diameters. - A subcatchment-to-network wiring step (`assign_subcatchment_outlets`) that ensures surface runoff actually enters the pipe network at a real upstream junction rather than dumping straight to the outfall. - Topology / hydraulic-attribute QA (`qa`). - Lightweight introspection (`summary`). - Export from network JSON to core SWMM INP sections (`export_inp`). ## When to use this skill …

How to install
mdr add zhonghao1995/agentic-swmm-workflow/swmm-network@sha256:c75b2759383bd933The line at the top of this page pins the label git:20260902.af3df3c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
