Install

Use this when you need to install ilo on a specific platform. Pick the section that matches who’s running it.

For agents

/plugin marketplace add ilo-lang/ilo   # add marketplace (once)
/plugin install ilo-lang/ilo           # install plugin + teach agent ilo

The agent learns ilo automatically via the bundled Agent Skill.

Browse Plugins → Add marketplace from GitHub → ilo-lang/ilo → install.

Binary auto-installs via npm. Note: Cowork uses the WASM build - HTTP and process builtins (get, pst, run, $) are not yet supported.

npx skills add ilo-lang/ilo

Install via the skills npm package (for Claude Code and AI agent workflows). Installs the ilo Agent Skill into any compatible agent environment.

Copy skills/ilo/ into your agent’s skills directory. Any tool supporting the Agent Skills standard will pick it up.
