What it does

Hmt Calibrate is an agent skill from psu-efd/pyHMT2D. Run automated Manning's n calibration against observed water surface elevations using Bayesian optimization or Nelder-Mead. Use this when the user wants to calibrate, optimize, or fit model parameters to observations.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Performance reviews. The repository describes itself as: Python Hydraulic Modeling Tools - 2D. The licence is MIT.

When your agent uses it

  • Wants to calibrate
  • Fit model parameters to observations

Example prompts

  • “/hmt-calibrate”

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Check that a project is open.
  2. Validate the observation file.
  3. Show available materials.
  4. Ask the user for calibration parameters. For each material to calibrate
  5. Build validated parameter specifications.
  6. Optional: single test evaluation at initial values to verify the setup.
  7. Ask for settings: number of iterations (default: automatic) and method ("gp" or "nelder-mead").
  8. Run the calibration.
  9. Report results: best parameter values table, best RMSE, iterations completed, history CSV path.

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 Calibrate loads about 597 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~597

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
Run automated Manning's n calibration against observed water surface elevations using Bayesian optimization or Nelder-Mead. Use this when the user wants to calibrate, optimize, or fit model parameters to observations.

Run automated Manning's n calibration against observed water surface elevations.

Prerequisites

  • Project opened from a base_case/ subdirectory
  • Observation CSV: columns x, y, wse or name, x, y, wse (comment lines start with #)
  • Solver paths configured in hmt_config.json

Steps

  1. Check that a project is open. If not, ask the user to run /hmt-open pointing to base_case/<project_file>.

  2. Validate the observation file. Ask the user for the observation CSV path (e.g., HWMs.dat).

    bash
    hmt-cli check_observation_format --args '{"csv_file": "<path>"}'

    Show the preview table. On error: report and ask for a corrected path.

  3. Show available materials.

    bash
    hmt-cli get_materials
  4. Ask the user for calibration parameters. For each material to calibrate:

    • Material name, minimum n, maximum n, optional initial guess
  5. Build validated parameter specifications.

    bash
    hmt-cli build_param_specs --args '{"specs": [
      {"type": "manning_n", "material_name": "<name>", "min": <min>, "max": <max>, "initial": <init>},
      ...
    ]}'

    Show the specs and confirm with the user.

  6. Optional: single test evaluation at initial values to verify the setup.

    bash
    hmt-cli evaluate_parameters --args '{"param_specs": <specs_with_initial_values>, "observation_csv": "<path>"}'

    If RMSE = 1e6, the simulation failed — check pyHMT2D.log before proceeding.

  7. Ask for settings: number of iterations (default: automatic) and method ("gp" or "nelder-mead").

  8. Run the calibration.

    bash
    hmt-cli run_calibration --args '{"param_specs": <specs>, "observation_csv": "<path>", "n_iterations": <N>, "method": "gp"}'

    Periodically show progress while waiting:

    bash
    tail -20 calib_progress.log
  9. Report results: best parameter values table, best RMSE, iterations completed, history CSV path.

Troubleshooting:

  • RMSE = 1,000,000 → check pyHMT2D.log for solver errors
  • Material not found → name must match exactly; copy from hmt-cli get_materials output
