glm-calibration

glm-calibration is a skill for Claude Code, Codex from cxcscmu/SkillLearnBench. It costs 20 tokens per session (340 once invoked), scanned A, original, MIT.

A calibration guide for GLM lake-temperature simulations. Calibration means adjusting model settings so its results better match real measurements.

In plain words
What is it for?
Use it to adjust light, mixing, wind, radiation, and heat-transfer settings, then compare results with observations using overall and deep-water RMSE.
Why use it?
It gives a structured order for changing key settings and checking whether each change improves the simulation's accuracy.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

glm-calibration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

GLM Calibration for Lake Temperature

Key Calibration Parameters (Lake Mendota)

Parameter Range Effect
Kw [0.1, 0.5] Light extinction; higher = less deep heating, stronger stratification
coef_mix_hyp [0.3, 0.7] Hypolimnetic mixing; higher = more deep mixing, warmer hypolimnion
wind_factor [0.7, 1.3] Wind speed multiplier; higher = more surface mixing
lw_factor [0.7, 1.3] Longwave radiation multiplier; affects surface energy balance
ch [0.0005, 0.002] Sensible heat transfer coefficient

Calibration Strategy

  1. Start with defaults, run, compute RMSE
  2. Adjust Kw first (strongest control on stratification)
  3. Then coef_mix_hyp (controls deep temperatures)
  4. Fine-tune wind_factor and lw_factor for surface/overall bias
  5. ch has moderate effect on surface heat exchange

RMSE Computation

  • Match observations to simulation by exact datetime and rounded depth
  • depth_sim = round(lake_depth - z) to get depth from surface
  • Overall RMSE, deep (>=13m) RMSE, summer deep (Jun-Sep, >=13m) RMSE

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

glm-calibration is a skill published in the GitHub repository cxcscmu/SkillLearnBench (83 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 340 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
