hmt-open

Open a pyHMT2D hydraulic model project and display its contents.

Usage

/hmt-open [project_file]

The project file path is optional — if omitted, this skill scans the current directory.

Steps

1. Find the project file. If the user provided a path in the command, use it directly. Otherwise, scan the current directory:

   hmt-cli list_model_files --args '{"directory": "."}'
   

   Show the found files as a table (file, model type, case name). If multiple files are found, ask the user which one to open. If none are found, tell the user no model files were detected and stop.

2. Open the project.

   hmt-cli get_project_info --args '{"project_file": "<path>"}'
   

   On error: report the message and stop. On success: report model type, case name, number of cells, number of material zones, and number of boundary conditions.

3. Show materials.

   hmt-cli get_materials
   

   Present as a Markdown table: ID | Name | Manning's n

4. Show boundary conditions. (run after step 3 completes — do NOT run in parallel)

   hmt-cli get_boundary_conditions
   

   Present as a Markdown table: ID | Name | Type | Value | Units

5. Look for a result file. (run after step 4 completes — do NOT run in parallel) Check the same directory for .h5, .hdf, or .hdf5 files. If found, offer to inspect available variables:

   hmt-cli get_result_variables --args '{"result_file": "<result_file>"}'
   

   Report: variable names and number of time steps.

   Important: Each hmt-cli call spawns a separate process that opens its own HEC-RAS COM instance. Always run these calls sequentially to avoid simultaneous instances that can cause file I/O conflicts.

6. Suggest next steps based on what was found:

   • If result file present: "Run /hmt-results to query simulation output."
   • If no result file: "Run /hmt-run to execute the simulation."
   • To change parameters: "Run /hmt-modify."
