Mise

Overview

Mise is a polyglot development tool manager that handles tool versions, environment variables, and task running in a single CLI. It replaces asdf, nvm, pyenv, direnv, and Makefiles with a unified mise.toml configuration per project.

When to use: Managing multiple language runtimes per project, defining reproducible dev environments, running project tasks with dependencies, replacing scattered .nvmrc/.python-version/.tool-versions files, automating CI pipelines.

When NOT to use: Container-only workflows where all tools live in Docker images, single-language projects already well-served by their native version manager, production runtime management (mise is a dev tool).

Version Resolution Order

Mise resolves tool versions by checking these sources in priority order:

  1. MISE_<TOOL>_VERSION environment variable
  2. mise.toml in current directory
  3. mise.toml in parent directories (walks up the tree)
  4. .tool-versions file (asdf compatibility)
  5. Legacy files (.nvmrc, .python-version, .ruby-version)
  6. ~/.config/mise/config.toml (global default)

Quick Reference

Pattern Command / Config Key Points
Install tools mise install Reads mise.toml, installs all listed tools
Pin tool version mise use node@22 Writes to mise.toml in current directory
Pin globally mise use -g node@22 Writes to ~/.config/mise/config.toml
Run a task mise run build Runs task defined in mise.toml
Run with args mise run test -- --watch Passes args after -- to the task
Watch mode mise watch build Re-runs task when sources change
List tasks mise tasks Shows all available tasks
Set env vars [env] section in mise.toml Per-directory, auto-activated on cd
Load .env file _.file = ".env" Loads dotenv into environment
Extend PATH _.path = ["./bin"] Prepends directories to PATH
List installed mise ls Shows all installed tool versions
Outdated tools mise outdated Shows tools with newer versions
Upgrade tools mise upgrade Upgrades tools to latest within constraints
Trust config mise trust Trusts mise.toml in current directory
Tool backends "npm:prettier" / "cargo:cargo-watch" Install from npm, cargo, pipx, GitHub, etc.
Task dependencies depends = ["lint", "test"] Prerequisite tasks run first
Incremental build sources + outputs on task Skips task if outputs newer than sources
Exec without activate mise exec -- node app.js Runs command with mise-managed tools
Diagnostics mise doctor Check installation and config health
Prune unused mise prune Remove tool versions not in any config
Generate hook mise generate git-pre-commit Generate git pre-commit hook for tasks
Env-specific config .mise.staging.toml Activated via MISE_ENV=staging
Shims for IDEs mise settings set shims_on_path true PATH-based shims for IDE compatibility

Common Mistakes

Mistake Correct Pattern
Using mise install node@22 without mise use mise use node@22 both installs and pins to mise.toml
Editing .tool-versions manually with mise Use mise use to update; mise.toml is preferred over .tool-versions
Forgetting mise trust on new project clone Run mise trust to activate untrusted config files
Using depends key for task dependencies Current key is depends (array), not deps
Running mise run without activating mise Run mise activate in shell profile or use mise exec
Putting secrets directly in mise.toml Use _.file = ".env.local" and gitignore the .env file
Expecting env vars without cd-ing into project Mise activates env on directory change; use mise env to debug
Using latest version in shared projects Pin specific major versions (node = "22") for reproducibility
Defining tasks in Makefile alongside mise Consolidate all tasks in mise.toml for one tool
Missing shebang in multi-line task scripts Add #!/usr/bin/env bash for explicit interpreter
Not using sources/outputs for slow tasks Define source globs for incremental skipping and watch mode
Using mise activate in non-interactive scripts Use mise exec or eval "$(mise env)" in scripts and CI

Delegation

  • Task pattern discovery: Use Explore agent
  • Configuration review: Use Task agent
  • CI pipeline integration: Use Task agent

If the rust skill is available, delegate Rust toolchain management patterns to it.
If the python-uv skill is available, delegate Python version and virtual environment patterns to it.
If the github-actions skill is available, delegate CI workflow patterns to it.
If the docker skill is available, delegate containerized workflow patterns to it.
If the pino-logging skill is available, delegate logging configuration patterns to it.
If the sentry skill is available, delegate error monitoring setup patterns to it.

How to use this skill

1

Install mise by running npx skills add oakoss/agent-skills --skill mise in your project directory. Run the install command above in your project directory. The skill file will be downloaded from GitHub and placed in your project.

2

No configuration needed. Your AI agent (Claude Code, Cursor, Windsurf, etc.) automatically detects installed skills and uses them as context when generating code.

3

The skill enhances your agent's understanding of mise, helping it follow established patterns, avoid common mistakes, and produce production-ready output.

What you get

Skills are plain-text instruction files — not executable code. They encode expert knowledge about frameworks, languages, or tools that your AI agent reads to improve its output. This means zero runtime overhead, no dependency conflicts, and full transparency: you can read and review every instruction before installing.

Compatibility

This skill works with any AI coding agent that supports the skills.sh format, including Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider, and other tools that read project-level context files. Skills are framework-agnostic at the transport level — the content inside determines which language or framework it applies to.

Data sourced from the skills.sh registry and GitHub. Install counts and security audits are updated regularly.
