Setup Engineering

Engineering ships as a full plugin (hook, subagents) and also as a vendored skill catalog. Vendoring carries the skills but not the hook or the agents, so a skills-only consumer loses the default-on entry point and the Claude-native targets that provider dispatch names. This skill installs that machinery into the target repo and, on Codex, the repo-scoped Codex config.

The machinery install is non-interactive and idempotent.

Install repo-level machinery

scripts/install-machinery.sh (in this skill's base directory) owns the idempotency and no-clobber contract. Run it rather than editing the target files by hand. It writes a single marker-delimited mandate block and leaves everything outside the markers untouched, so re-running updates in place with no duplication.
