feature-engineering SKILL.md skillA
feature-engineering from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/feature-engineering@git:20260411.b88fc6fPins git:20260411.b88fc6f in mdr.lock. Pin the fingerprint instead.

Use when building or improving time series forecasting models and the user asks about exogenous variables, calendar features, rolling statistics, cyclical encoding, differencing, or feature scaling — or when forecast accuracy has plateaued and new features may help.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Feature Engineering ## References See [references/rolling-stats-reference.md](references/rolling-stats-reference.md) for the complete `RollingFeatures` constructor, all 9 available statistics, feature name generation formula, window behavior, and `kwargs_stats` usage. ## When to Use This Skill - Forecast accuracy has plateaued and you suspect better features would help - User asks about "exogenous variables", "external regressors", or "feature creation" - Time series has calendar patterns (hourly, weekly, seasonal) not yet captured - Raw datetime index is used directly instead of engineered features - User mentions feature_engine, RollingFeatures, or skforecast preprocessing - Energy/transport/outdoor domain where sunlight hours may be predictive ### When NOT to Use - **Tabular ML (non-time-series)**: Use a general feature engineering skill instead - **Deep learning forecasters** (RNNs, Transformers): These learn features internally; manual engineering adds less value - **Feature selection/importance**: This skill covers creation, not selection — use model-based selection after creating features …

How to install
mdr add lu1sdv/skillsmd/feature-engineering@sha256:36f3e00596bae219The line at the top of this page pins the label git:20260411.b88fc6f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
