Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# asdf Version Manager Skill asdf is a universal CLI version manager — one tool to replace nvm, pyenv, rbenv, tfenv, goenv and more. It manages per-project versions via `.tool-versions` files and switches versions automatically as you navigate directories. --- ## When to Use This Skill Use this skill when the user is: - **Installing or setting up asdf** on a new machine (any OS, any shell) - **Adding plugins** for a language or tool (Node.js, Python, Go, Terraform, kubectl, Helm, etc.) - **Installing or switching versions** of any tool managed by asdf - **Managing `.tool-versions` files** — creating, editing, or understanding version resolution - **Migrating from single-language version managers** like nvm, pyenv, rbenv, goenv, tfenv, or sdkman - **Configuring shell integration** for Bash, Zsh, Fish, or Elvish - **Debugging version resolution** — wrong version active, shims not working, `command not found` errors - **Onboarding to a project** that uses `.tool-versions` for reproducible environments - **Setting up CI/CD pipelines** that need deterministic tool versions via asdf - **Configuring `.asdfrc`** for legacy file support, concurrency, or plugin repository settings --- …

How to install
mdr add jjmartres/ai-coding-agents/asdf@sha256:88efb80f1be000f9The line at the top of this page pins the label git:20260420.c9ed657, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
