Use when a feature pipeline has accumulated expensive inputs with negligible marginal accuracy; weighs each feature's permutation importance against its licensing cost, compute cost and inference latency before pruning.

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

## When to Use

Invoke this skill when optimizing an ML feature pipeline for production deployment. Production pipelines accumulate feature bloat: dozens of expensive features (high-latency order-book depth metrics, alternative-data API subscriptions, multi-resolution convolutions) that add negligible marginal accuracy while inflating infrastructure spend and inference latency. This skill scores each feature's marginal contribution against its monthly cost and its share of the inference latency budget, and returns a `KEEP` / `REVIEW` / `PRUNE` verdict per feature plus a *realizable* savings figure for the pipeline.

## When NOT to Use

- **Feature *selection* during model fitting.** This skill audits an already-fitted model's feature set. Choosing features as part of training (and validating that choice across folds) belongs to `feature-selection-stability-across-folds`.
- **Detecting that a feature's importance has *changed*.** A drop in importance over time is drift, not a cost-benefit question — see `feature-importance-drift-monitoring`.

How to install

The exact contents, by fingerprint
mdr add himanshuj16/algo-trading-skills/feature-engineering-cost-benefit-tracking@sha256:32165efcc8b3e111

The line at the top of this page pins the label v2.0.0, 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.
