ilo ships a Claude Code skill that teaches the assistant how to run builds, tests, and other tooling inside your ilo-managed build environment instead of on the host. Once installed, Claude recognizes that a project uses ilo — from a .ilo.rc, dev/ argument files, a Containerfile, a devcontainer.json, a devfile.yaml, or a compose file — and reaches for ilo automatically when a command needs a toolchain the host does not have.

The skill is distributed as a plugin hosted in the ilo repository, so installing it needs nothing more than git and a Claude Code client.

Requirements

• Claude Code (the CLI, desktop, or IDE client). Skills are a Claude Code feature; the claude.ai web app has no skill installation flow.
• The ilo binary on your PATH — see Install.

Install

Add the marketplace once, then install the plugin:

# add the metio marketplace (hosted in the ilo repository)
/plugin marketplace add metio/ilo

# install the ilo skill from it
/plugin install ilo@metio

metio is the marketplace and ilo is the plugin, so the install reference is ilo@metio. After installing, the skill activates on its own whenever it is relevant — you do not type a command to invoke it.

What it does

With the skill installed, Claude will:

• run build/test/tooling commands through ilo (for example ilo @dev/build, or an ad-hoc ilo go test ./... when a project has an .rc file) instead of on the host;
• prefer non-interactive runs suited to automation;
• consult ilo --help / ilo <subcommand> --help as the source of truth for the exact flags your installed version supports.

Bash(ilo *) is pre-approved by the skill, so ilo invocations run without a permission prompt. Everything else still goes through Claude Code’s normal permission flow.

Updating

Refresh the marketplace cache, then reinstall to move an already-installed plugin to the latest version:

# pull the latest marketplace contents
/plugin marketplace update metio

# reinstall to pick up the new version
/plugin install ilo@metio

Alternatively, enable auto-update for the metio marketplace in the /plugin UI (or set "autoUpdate": true for it in your settings) and Claude Code keeps the plugin current for you.

Because the skill is distributed separately from the ilo binary, it documents the stable command surface and defers to ilo --help for version-specific details — so it keeps working even when your installed ilo is a little ahead of or behind the skill.
