mise Skill

mise (pronounced "meez", short for mise-en-place) is a single static binary that does three jobs that usually take three tools:

Job	Tools it replaces	Where it lives in config
Manage tool/language versions per project	asdf, nvm, rbenv, pyenv	`[tools]`
Switch environment variables per directory	direnv, dotenv	`[env]`
Run project tasks	make, npm scripts, just	`[tasks.*]` + `mise run`

Everything lives in one committed mise.toml. This skill enforces a consistent house style so every project's mise config reads the same way, and treats mise.toml as source-controlled infra: pinned, reviewable, reproducible.

Before you touch anything

mise.toml can execute code (via [tasks], env._.source, env._.file). Two habits keep that safe and predictable:
