h2o

h2o is a skill for Claude Code, Codex from LeoLin990405/r-analytics-skill. It costs 25 tokens per session (502 once invoked), scanned A, original, MIT.

An R interface to H2O, a platform for running machine-learning jobs across available computing resources. It includes automated model selection and several built-in model types.

In plain words
What is it for?
Use it to import and split data, run AutoML, train models such as random forests or deep neural networks, and evaluate predictions.
Why use it?
It helps handle larger machine-learning workloads and compare several models without implementing each algorithm separately.

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

h2o 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 9d 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

h2o Package

Scalable machine learning platform.

Initialize

library(h2o)
h2o.init(nthreads = -1, max_mem_size = "8G")

# Import data
df_h2o <- as.h2o(df)
df_h2o <- h2o.importFile("data.csv")

# Split
splits <- h2o.splitFrame(df_h2o, ratios = c(0.8), seed = 123)
train <- splits[[1]]
test <- splits[[2]]

AutoML

aml <- h2o.automl(
  x = predictors,
  y = "target",
  training_frame = train,
  max_runtime_secs = 300,
  seed = 123
)

# Leaderboard
aml@leaderboard

# Best model
best <- aml@leader
h2o.performance(best, test)

Individual Models

# GLM
glm <- h2o.glm(x = predictors, y = "target",
  training_frame = train, family = "binomial")

# Random Forest
rf <- h2o.randomForest(x = predictors, y = "target",
  training_frame = train, ntrees = 100)

# GBM
gbm <- h2o.gbm(x = predictors, y = "target",
  training_frame = train, ntrees = 100, learn_rate = 0.1)

# XGBoost
xgb <- h2o.xgboost(x = predictors, y = "target",
  training_frame = train, ntrees = 100)

# Deep Learning
dl <- h2o.deeplearning(x = predictors, y = "target",
  training_frame = train, hidden = c(200, 200))

Predictions

pred <- h2o.predict(model, test)
perf <- h2o.performance(model, test)
h2o.auc(perf)
h2o.confusionMatrix(perf)

Save/Load

h2o.saveModel(model, path = "models/")
model <- h2o.loadModel("models/model_id")

Shutdown

h2o.shutdown(prompt = FALSE)
Changes

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.

h2o is a skill published in the GitHub repository LeoLin990405/r-analytics-skill (5 stars, last pushed 6mo ago), licensed MIT. It adds 25 tokens to every session and 502 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.
