Install

npx devlyn-cli

That's it. The installer opens with a single **agent selector** — pick any combination of **Claude Code**, **Codex CLI**, **oh-my-pi (omp)**, **Pi**, or **Grok Build CLI**, and devlyn installs into every one you choose in a single pass. Claude Code and any agent already present on your machine are pre-checked, so the common case is just Enter. Skill-capable agents receive the `devlyn:resolve`, `devlyn:ideate`, and `devlyn:design-ui` skills — plus the `devlyn:engines` and `devlyn:queue` utilities — in the directory each one loads from: Codex → `~/.codex/skills/`, Grok → `~/.grok/skills/`, while **omp and Pi share `~/.agents/skills/`** — the cross-agent standard both read — so the bundle is written there once, not duplicated per agent. In Codex / omp / Pi, invoke them as skills (`$devlyn:resolve`, `$devlyn:ideate`, `$devlyn:design-ui`); in Claude Code and Grok Build CLI they're slash commands (`/devlyn:resolve`). Run it again anytime to update. (`npx devlyn-cli -y` installs the Claude core non-interactively; `npx devlyn-cli agents ` adds one agent lat
