What it does
Hmt Open is an agent skill from psu-efd/pyHMT2D. Open a pyHMT2D hydraulic model project (SRH-2D or HEC-RAS) and display its materials, boundary conditions, and available result variables. Use this when the user wants to open, load, or inspect a hydraulic model.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Python Hydraulic Modeling Tools - 2D. The licence is MIT.
When your agent uses it
- Inspect a hydraulic model
Example prompts
- “/hmt-open”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Find the project file.
- Open the project.
- Show materials.
- Show boundary conditions. (run after step 3 completes — do NOT run in parallel)
- Look for a result file. (run after step 4 completes — do NOT run in parallel)
- Suggest next steps based on what was found
What it can do on your machine
Read from SKILL.md and the folder at commit 57645ff. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Hmt Open loads about 593 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 270 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Open a pyHMT2D hydraulic model project (SRH-2D or HEC-RAS) and display its materials, boundary conditions, and available result variables. Use this when the user wants to open, load, or inspect a hydraulic model.
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
Find the project file. If the user provided a path in the command, use it directly. Otherwise, scan the current directory:
bash 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.
Open the project.
bash 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.
Show materials.
bash hmt-cli get_materialsPresent as a Markdown table: ID | Name | Manning's n
Show boundary conditions. (run after step 3 completes — do NOT run in parallel)
bash hmt-cli get_boundary_conditionsPresent as a Markdown table: ID | Name | Type | Value | Units
Look for a result file. (run after step 4 completes — do NOT run in parallel) Check the same directory for
.h5,.hdf, or.hdf5files. If found, offer to inspect available variables:bash hmt-cli get_result_variables --args '{"result_file": "<result_file>"}'Report: variable names and number of time steps.
Important: Each
hmt-clicall 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.Suggest next steps based on what was found:
- If result file present: "Run
/hmt-resultsto query simulation output." - If no result file: "Run
/hmt-runto execute the simulation." - To change parameters: "Run
/hmt-modify."
- If result file present: "Run
The session is automatically saved to .hmt_session.json by each hmt-cli call.
