  • You need to adjust model parameters to minimize RMSE between simulated and observed temperatures

What it does

Glm Calibration is an agent skill from benchflow-ai/skillsbench. Calibrate GLM parameters for water temperature simulation. Use when you need to adjust model parameters to minimize RMSE between simulated and observed temperatures.

Its SKILL.md is about 780 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: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is MIT.

When your agent uses it

  • You need to adjust model parameters to minimize RMSE between simulated and observed temperatures
  • Tasks that involve Performance reviews

Example prompts

  • “/glm-calibration”

Requirements

  • Python 3

Workflow steps

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

  1. Start with default parameters, run GLM, calculate RMSE
  2. Adjust one parameter at a time
  3. If surface too warm → increase wind_factor
  4. If deep water too warm → increase Kw
  5. If stratification too weak → decrease coef_mix_hyp
  6. Iterate until RMSE < 2.0°C

What it can do on your machine

Read from SKILL.md and the folder at commit 9a1f4dd. 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 python).

    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

Glm Calibration loads about 783 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~783

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.

GLM Calibration Guide

Overview

GLM calibration involves adjusting physical parameters to minimize the difference between simulated and observed water temperatures. The goal is typically to achieve RMSE < 2.0°C.

Key Calibration Parameters

ParameterSectionDescriptionDefaultRange
Kw&lightLight extinction coefficient (m⁻¹)0.30.1 - 0.5
coef_mix_hyp&mixingHypolimnetic mixing coefficient0.50.3 - 0.7
wind_factor&meteorologyWind speed scaling factor1.00.7 - 1.3
lw_factor&meteorologyLongwave radiation scaling1.00.7 - 1.3
ch&meteorologySensible heat transfer coefficient0.00130.0005 - 0.002

Parameter Effects

ParameterIncrease EffectDecrease Effect
KwLess light penetration, cooler deep waterMore light penetration, warmer deep water
coef_mix_hypMore deep mixing, weaker stratificationLess mixing, stronger stratification
wind_factorMore surface mixingLess surface mixing
lw_factorMore heat inputLess heat input
chMore sensible heat exchangeLess heat exchange

Calibration with Optimization

python
from scipy.optimize import minimize

def objective(x):
    Kw, coef_mix_hyp, wind_factor, lw_factor, ch = x

    # Modify parameters
    params = {
        'Kw': round(Kw, 4),
        'coef_mix_hyp': round(coef_mix_hyp, 4),
        'wind_factor': round(wind_factor, 4),
        'lw_factor': round(lw_factor, 4),
        'ch': round(ch, 6)
    }
    modify_nml('glm3.nml', params)

    # Run GLM
    subprocess.run(['glm'], capture_output=True)

    # Calculate RMSE
    rmse = calculate_rmse(sim_df, obs_df)
    return rmse

# Initial values (defaults)
x0 = [0.3, 0.5, 1.0, 1.0, 0.0013]

# Run optimization
result = minimize(
    objective,
    x0,
    method='Nelder-Mead',
    options={'maxiter': 150}
)

Manual Calibration Strategy

  1. Start with default parameters, run GLM, calculate RMSE
  2. Adjust one parameter at a time
  3. If surface too warm → increase wind_factor
  4. If deep water too warm → increase Kw
  5. If stratification too weak → decrease coef_mix_hyp
  6. Iterate until RMSE < 2.0°C

Common Issues

IssueLikely CauseSolution
Surface too warmLow wind mixingIncrease wind_factor
Deep water too warmToo much light penetrationIncrease Kw
Weak stratificationToo much mixingDecrease coef_mix_hyp
Overall warm biasHeat budget too highDecrease lw_factor or ch

Best Practices

  • Change one parameter at a time when manually calibrating
  • Keep parameters within physical ranges
  • Use optimization for fine-tuning after manual adjustment
  • Target RMSE < 2.0°C for good calibration
