mle-workflow

A workflow for turning machine-learning experiments into repeatable systems that can be trained, evaluated, deployed, monitored, and rolled back.

In plain words
What is it for?
Use it for ranking, recommendations, classification, forecasting, embeddings, language-model workflows, anomaly detection, and batch analytics.
Why use it?
It addresses problems such as changing data, unreliable training results, mismatched model versions, and failures after deployment.

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

mle-workflow 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 yesterday.

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.

Machine Learning Engineering Workflow

Use this skill to turn model work into a production ML system with clear data contracts, repeatable training, measurable quality gates, deployable artifacts, and operational monitoring.

When to Activate

  • Planning or reviewing a production ML feature, model refresh, ranking system, recommender, classifier, embedding workflow, or forecasting pipeline
  • Converting notebook code into a reusable training, evaluation, batch inference, or online inference pipeline
  • Designing model promotion criteria, offline/online evals, experiment tracking, or rollback paths
  • Debugging failures caused by data drift, label leakage, stale features, artifact mismatch, or inconsistent training and serving logic
  • Adding model monitoring, canary rollout, shadow traffic, or post-deploy quality checks

Scope Calibration

Use only the lanes that fit the system in front of you. This skill is useful for ranking, search, recommendations, classifiers, forecasting, embeddings, LLM workflows, anomaly detection, and batch analytics, but it should not force one architecture onto all of them.

  • Do not assume every model has supervised labels, online serving, a feature store, PyTorch, GPUs, human review, A/B tests, or real-time feedback.
  • Do not add heavyweight MLOps machinery when a data contract, baseline, eval script, and rollback note would make the change reviewable.
  • Do make assumptions explicit when the project lacks labels, delayed outcomes, slice definitions, production traffic, or monitoring ownership.
  • Treat examples as interchangeable scaffolds. Replace metrics, serving mode, data stores, and rollout mechanics with the project-native equivalents.
  • python-patterns and python-testing for Python implementation and pytest coverage
  • pytorch-patterns for deep learning models, data loaders, device handling, and training loops
  • eval-harness and ai-regression-testing for promotion gates and agent-assisted regression checks
  • database-migrations, postgres-patterns, and clickhouse-io for data storage and analytics surfaces
  • deployment-patterns, docker-patterns, and security-review for serving, secrets, containers, and production hardening

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.

mle-workflow is a skill published in the GitHub repository affaan-m/ECC (245,028 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 4,645 once invoked, about $0.0002 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 2026-08-30.
