Automated summary
This skill explains how to install and configure mise to pin multiple language versions per project and define runnable tasks in mise.toml.
Strengths
- Covers installation, shell activation, and a full mise.toml example with [tools], [env], and [tasks]
- Clearly positions mise as a single replacement for nvm, pyenv, rbenv, and asdf
- Notes backward compatibility with .tool-versions, .node-version, and .python-version files
- Shows how project tasks can replace Makefiles and package.json scripts
Limitations
- Does not detail plugin handling or tools beyond the example list
- Assumes bash for the activation line; zsh and fish are not covered
- Claims a 10-100x speedup over asdf without giving a way to verify it
Use it when a project needs pinned Node.js, Python, or Go versions plus one entry point for common tasks.
Skip it if the target environment is native Windows or the team is already committed to a single existing manager like asdf and has no migration plans.
Security analysis
CautionThe skill instructs installing mise via curl https://mise.run | sh, a common but potentially risky pattern since the remote script executes with user privileges and is not verified. It also appends to ~/.bashrc. These actions are legitimate for a version manager but warrant caution due to the power of remote code execution and shell configuration changes.
- •Uses curl | sh to download and execute a remote script without integrity verification.
- •Modifies user shell configuration (~/.bashrc) by appending eval activation.
- •Commands involve network installation and shell execution, though for a legitimate version manager.
Examples
Set up mise for this repo: create a mise.toml that pins Node 20, Python 3.12 and Go 1.22, then run mise install and confirm the versions.We currently use nvm for Node and pyenv for Python. Replace both with mise, reusing our existing version files where possible.Add dev and test tasks to mise.toml so we can run them with mise run, and include a DATABASE_URL in the env section.name: mise description: >- Manage tool versions and tasks with mise (formerly rtx). Use when a user asks to manage Node.js/Python/Go versions per project, replace nvm/pyenv/asdf, or define project-level tool requirements. license: Apache-2.0 compatibility: 'Linux, macOS, WSL' metadata: author: terminal-skills version: 1.0.0 category: development tags: - mise - version-manager - asdf - nvm - polyglot
mise
Overview
mise manages tool versions — Node.js, Python, Go, Rust, Ruby, etc. One tool replaces nvm, pyenv, rbenv, and asdf. Also runs project tasks.
Instructions
Step 1: Install
curl https://mise.run | sh
echo 'eval "$(mise activate bash)"' >> ~/.bashrc
Step 2: Configuration
# mise.toml — Project tool versions and tasks
[tools]
node = "20"
python = "3.12"
go = "1.22"
[env]
DATABASE_URL = "postgresql://localhost/myapp"
[tasks.dev]
run = "npm run dev"
[tasks.test]
run = "npm test"
mise install # install all tools
mise run dev # run task
Guidelines
- mise is 10-100x faster than asdf (Rust vs bash).
- Reads .tool-versions, .node-version, .python-version — drop-in replacement.
- Tasks in mise.toml replace Makefiles and package.json scripts.
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/manage-tool-versions-and-tasks-with-mise-muar2zcs/download' --output '.skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs/SKILL.md.part' && mv '.skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs/SKILL.md.part' '.skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Environment declared by the author: Linux, macOS, WSL
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/manage-tool-versions-and-tasks-with-mise-muar2zcs/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.

Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
