zenml: Skill for Claude Code

.agents/skills/zenml-repo-workflows/SKILL.md

zenml-repo-workflows is a skill for Claude Code, Codex from zenml-io/zenml. It costs 35 tokens per session (4,588 once invoked), scanned A, original, Apache-2.0.

A set of development procedures for contributing to the ZenML code repository, a project that helps run machine-learning workflows.

In plain words
What is it for?
Use it when working on ZenML features, bug fixes, database migrations, documentation, integrations, models, orchestrators, servers, or storage.
Why use it?
It explains the repository's expectations for tests, code style, migrations, documentation, integrations, and pull requests. This reduces uncertainty when changing shared project code.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md; mentions Codex.

This is zenml-io/zenml's own configuration. It tells Claude Code and Codex how to work on zenml itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything zenml configures →

About the project

ZenML is a Python framework for turning machine-learning and AI workflows into tracked pipelines that run on different infrastructure backends. It is for ML and AI engineers building applications such as model-training workflows, language-model systems, and agent loops in company environments.

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

zenml-repo-workflows 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 11d ago.

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.

ZenML Repo Workflows

Use this skill when work in the ZenML repository needs more detail than the always-loaded AGENTS.md files provide. The root guide keeps safety rules, universal conventions, and the most common commands in memory. This skill keeps the longer recipes, examples, and subsystem checklists.

Development Workflow

Setup

  • Install ZenML in development mode with dev dependencies.
  • ZenML recommends uv for Python package installation because it resolves dependencies more quickly and reliably than plain pip.
  • Useful development environment variables:
    • ZENML_LOGGING_VERBOSITY=DEBUG
    • MLSTACKS_ANALYTICS_OPT_OUT=true
    • AUTO_OPEN_DASHBOARD=false
    • ZENML_ENABLE_RICH_TRACEBACK=false
    • TOKENIZERS_PARALLELISM=false
  • Always set the following environment variables when developing:
    • ZENML_ANALYTICS_OPT_IN=false: Disables analytics during development
    • ZENML_DEBUG=true: Uses the development ZenML analytics server to avoid sending analytics to the official ZenML analytics server (IMPORTANT!). This must be set even if ZENML_ANALYTICS_OPT_IN=true because in a client-server setup, the server controls the client-side analytics opt-in status.

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.
