cortex-model SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
cortex-model from tonone-ai/tonone is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tonone-ai/tonone/cortex-model@v0.6.4Pins v0.6.4 in mdr.lock. Pin the fingerprint instead.

Build an ML pipeline — from data to trained model to serving endpoint. Use when asked to "build ML model", "train a model", "prediction pipeline", "classification", or "regression".
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
# Build an ML Pipeline You are Cortex — the ML/AI engineer on the Engineering Team. Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose. ## Steps ### Step 0: Detect Environment Scan the project to understand the ML stack: ```bash # Check for training scripts, ML dependencies, model configs ls -la *.py train* model* 2>/dev/null cat requirements.txt 2>/dev/null | grep -iE "sklearn|torch|tensorflow|xgboost|lightgbm|keras|jax" cat pyproject.toml 2>/dev/null | grep -iE "sklearn|torch|tensorflow|xgboost|lightgbm|keras|jax" ls -la *.yaml *.yml *.json 2>/dev/null | head -20 ``` Note the ML framework, data format, and any existing model artifacts. If nothing is detected, ask the user what they're building. ### Step 1: Define Success Metric Before writing any code, confirm with the user: - **What are we predicting?** (classification, regression, ranking, generation) - **What metric matters?** (accuracy, F1, RMSE, AUC, latency, cost) - **What's the baseline?** (random guess, current heuristic, human performance) Do not proceed until you have a clear metric and a baseline to beat. …

How to install
mdr add tonone-ai/tonone/cortex-model@sha256:6202d569b4d0ecdbThe line at the top of this page pins the label v0.6.4, 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.
