mise-configurator

mise-configurator is a skill for Claude Code, Codex from beel-collab/presets.dev. It costs 21 tokens per session (887 once invoked), scanned A, original, MIT.

A configuration generator for mise, a tool that installs and selects consistent versions of programming languages and development tools.

In plain words
What is it for?
It is for creating or updating mise.toml files, migrating from tools such as asdf, nvm, or pyenv, and setting up mixed-language projects and CI pipelines.
Why use it?
It helps teams standardize tool versions, simplify project setup, and make local and CI environments reproducible, including in monorepos where many projects share one repository.

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

mise-configurator 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 4d 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.

Mise Configurator

Overview

This skill generates clean, production-ready mise.toml configurations for local development environments and CI/CD pipelines.

It helps standardize runtime versions, simplify onboarding, replace legacy version managers like asdf, nvm, and pyenv, and create reproducible multi-language environments with minimal setup effort.

When to Use This Skill

  • Use when you need to create or update a mise.toml
  • Use when working with Node.js, Python, Go, Rust, Java, Bun, Terraform, or mixed stacks
  • Use when the user asks about CI/CD runtime setup using mise
  • Use when migrating from .tool-versions, asdf, nvm, or pyenv
  • Use when standardizing tool versions across teams or monorepos

How It Works

Step 1: Detect Project Context

Inspect available repository files such as:

  • package.json
  • pnpm-lock.yaml
  • pyproject.toml
  • requirements.txt
  • go.mod
  • Cargo.toml
  • .tool-versions
  • Dockerfile
  • GitHub Actions or CI files

Infer languages, package managers, and pinned versions.

Step 2: Generate mise.toml

Create a minimal, valid, copy-paste-ready configuration using:

  • existing pinned versions when found
  • explicit user-provided target versions when absent
  • practical defaults for developer productivity
  • concrete pinned versions in shared production configs

Step 3: Add Bootstrap Commands

Provide setup commands such as:

mise trust
mise install

Step 4: Generate CI/CD Integration

If requested, generate pipeline examples using mise with caching and runtime installation.

Examples

Example 1: Node.js + pnpm Project

[tools]
node = "22.11.0"
pnpm = "9.15.0"

Example 2: Python + GitHub Actions

[tools]
python = "3.12.7"
poetry = "1.8.4"
steps:
  - uses: actions/checkout@v4
  - uses: jdx/mise-action@v2
  - run: poetry install
  - run: pytest

Best Practices

  • ✅ Respect versions already pinned in the repository

  • ✅ Keep configs minimal and readable
