Evaluate model performance — check for accuracy drops, data drift, and error patterns. Use when asked about "model accuracy dropped", "evaluate the model", "check for drift", or "model performance".
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
# Evaluate Model Performance 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: Run Static Analysis Before any LLM-based evaluation, run the static analysis scanner to find LLM usage anti-patterns and prompt quality issues: ```bash # From the project root (or team/cortex/scripts/) python team/cortex/scripts/cortex_agent/eval_scan.py . --out .reports/cortex-eval-latest.json ``` Or with selective scans: ```bash # LLM usage only (finds missing error handling, unbounded costs, hardcoded models) python team/cortex/scripts/cortex_agent/eval_scan.py . --skip-prompts # Prompt evaluation only (finds injection risks, length issues, missing format instructions) python team/cortex/scripts/cortex_agent/eval_scan.py . --skip-usage ``` Review the JSON report at `.reports/cortex-eval-<ts>.json`. Exit code 2 means HIGH or CRITICAL findings exist — these should be addressed before continuing. ### Step 1: Detect ML Environment Scan the project to understand the ML stack and current model: ```bash …

How to install
mdr add jeremylongshore/tons-of-skills-marketplace/cortex-eval@sha256:3db4083209d78578The line at the top of this page pins the label v0.9.8, 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.
