What it does
- Walks through installing asdf and wiring up shell integration for Bash, Zsh, and Fish (including completions).
- Collects the essential commands:
asdf plugin add,asdf install,asdf set(the modern replacement forlocal/globalsince v0.15+). - Explains
.tool-versionssyntax and version resolution order (cwd → parent dirs →$HOME→ASDF_${TOOL}_VERSION), plus.asdfrcoptions. - Covers migration from nvm, pyenv, rbenv, goenv, tfenv via
legacy_version_filewith a legacy-file mapping table. - Provides troubleshooting recipes for shims,
command not found, PATH ordering, and plugin build dependencies.
Who it's for
- Developers consolidating multiple language version managers into one tool.
- DevOps/cloud engineers pinning Terraform, kubectl, Helm, and gcloud versions per project.
- Teams onboarding new members into repos that rely on
.tool-versionsfor reproducible environments.
Example uses
- "Set up asdf on a fresh machine with Fish shell" → dependencies, clone,
config.fishentry, completion symlink. - "Match this repo's
.tool-versions" → add the needed plugins, runasdf install, verify withasdf current. - "node keeps resolving to the wrong version" → inspect
asdf current, check PATH, runasdf reshim.

Install the skill I found on Claude Skill Mart. Copy the opencode/skills/asdf folder from the GitHub repo jjmartres/opencode into my ~/.claude/skills/asdf/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/jjmartres/opencode.git /tmp/opencode && mkdir -p ~/.claude/skills && cp -r /tmp/opencode/opencode/skills/asdf ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Create the skills directory if needed:
mkdir -p ~/.claude/skills - Clone the repo to a temp folder:
git clone https://github.com/jjmartres/opencode.git /tmp/opencode - Copy just this skill:
cp -r /tmp/opencode/opencode/skills/asdf ~/.claude/skills/ - Confirm the file exists:
ls ~/.claude/skills/asdf/SKILL.md - Restart Claude Code and try a prompt like "use asdf to pin Node 20 for this project".
