What it does

Mlflow Mlops Migration is an agent skill from pproenca/dot-skills. Guided workflow for taking any ML codebase — including one with no experiment tracking at all, or one full of MLflow 2-era idioms — to a production-grade open-source MLflow 3 setup with dev/staging/prod environments, registry-based promotion, and served models. Walks seven phases with a developer who may have zero MLflow 3 experience — assess the codebase (scripted read-only audit), model the registry domain (per-environment model names, aliases, gates), stand up tracking per environment, restructure training…

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including scripts and reference files (for example `config.json`, `gotchas.md` and `hooks/hooks.json`).

It sits in DevOps & Cloud, covering MLOps, Meeting notes and agendas and QA and bug reports. It works with MLflow. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.

When your agent uses it

  • Asked to set up MLflow
  • Migrate to MLflow 3
  • Productionize model training and serving
  • Design a dev/staging/prod MLOps cycle

Example prompts

  • “/mlflow-mlops-migration”

Requirements

  • Python 3
  • A Bash shell
  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mlflow Mlops Migration loads about 1.9k tokens when it runs, and up to ~8.5k if it reads all its reference files. Until then it costs about 214 tokens; SKILL.md has 722 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~214
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Guided workflow for taking any ML codebase — including one with no experiment tracking at all, or one full of MLflow 2-era idioms — to a production-grade open-source MLflow 3 setup with dev/staging/prod environments, registry-based promotion, and served models. Walks seven phases with a developer who may have zero MLflow 3 experience — assess the codebase (scripted read-only audit), model the registry domain (per-environment model names, aliases, gates), stand up tracking per environment, restructure training code to MLflow 3 idioms, wire evaluation-gated promotion, serve and smoke-test, then run the ongoing MLOps loop. Use when asked to set up MLflow, migrate to MLflow 3, productionize model training and serving, or design a dev/staging/prod MLOps cycle. Pairs with the sibling mlflow-3 rule pack for every API decision.

MLflow MLOps Migration

A phased, gated workflow that turns an arbitrary ML codebase — however unstructured — into a production-grade open-source MLflow 3 setup covering the full MLOps cycle: tracked experiments, a domain-modelled registry, dev/staging/prod separation, evaluation-gated promotion, and served models. It is written to be driven with a developer who has no MLflow 3 experience: every phase produces a reviewable artifact before anything is changed, and every API decision defers to the sibling mlflow-3 rule pack (which is pinned to mlflow 3.15.1 and names the MLflow 2-era idioms this migration exists to remove).

When to Apply

Use this skill when:

  • A team wants MLflow (or has a messy/partial MLflow 2 setup) and needs the path to a production-grade MLflow 3 deployment — not just API fixes.
  • Training code exists but experiments are untracked, models are shipped by copying files, or "deployment" means a pickle in a bucket.
  • You are asked to design or review a dev/staging/prod model-promotion story.
  • An MLflow 2 → 3 migration touches infrastructure (stages, ./mlruns file stores, MLServer), not only client code.

Don't use it for a single API question — read the relevant mlflow-3 rule directly.

✓Run scripts/verify.sh after phases 2–5Pass/fail assertion reportread-only

Phases run in order — each has entry/exit criteria in references/workflow.md, and scripts/verify.sh is the exit gate for the infrastructure phases. Re-running any phase is safe: 00-assess.sh regenerates only its own report (and refuses to clobber anything else), scaffold-dev-tracking.sh refuses to overwrite (exit code 2 = already done), and verify.sh only reads. The one non-idempotent step is promotion's copy_model_version — see references/promotion.md for how to resume instead of re-copying.

Risk Level: Write

This workflow edits training code, writes infrastructure files, and stands up services. Guardrails:

  • Nothing in phase 0–1 modifies anything — always complete both before touching code or infra.
  • Confirm with the user before: starting/replacing any tracking server, rewriting a training entrypoint, flipping a prod @champion alias (dev/staging flips may be automated by the phase-4 pipeline), and exposing a serving endpoint beyond localhost.
  • Two maintenance commands are destructive and must be run only with explicit user confirmation and a stated reason: mlflow gc (permanently deletes soft-deleted runs and experiments — registry entities are untouched) and mlflow db upgrade (irreversible schema migration — snapshot the database first). A PreToolUse hook in hooks/hooks.json blocks both unless MLFLOW_MAINTENANCE_ACK=yes is set for that command, so they cannot run un-confirmed by accident.

Requirements

  • Python ≥ 3.10 with mlflow==3.15.1 installed in the project environment
  • bash, curl, jq — the scripts use them
  • uv — the serving phase uses --env-manager uv for fast isolated environment rebuilds (substitute virtualenv everywhere if uv is unavailable)
  • Docker + docker-compose — for the dev tracking stack and build-docker serving images
  • A database + object store per shared environment (staging/prod) — PostgreSQL/MySQL and S3/GCS/Azure; dev runs on the scaffolded local stack
  • The sibling mlflow-3 skill — phase 3 cites its rules; if it is not installed, read the MLflow 3 migration guide instead (the workflow still works, with more manual verification)

Setup

config.json starts empty. Phase 2 fills it (tracking URIs per environment, registry namespace, model name, serving URL). If fields are empty when a script needs them, the script says which ones — fill them via the _setup_instructions in the file.
