# Engineering onboarding A skill for writing an onboarding guide for an engineer joining a team that consumes the design system, grounded in the team's actual repository and stack. ## Before you begin: verify references Before doing anything else, confirm that every file listed in this skill's frontmatter `references:` field exists at its relative path from this SKILL.md. If any are missing, stop — the install is incomplete. This usually means a third-party installer (for example `npx skills install`) flattened the skill into a standalone folder and dropped the repo-root `knowledge-notes/` directory this skill depends on. Tell the user to reinstall using a supported method from `1-INSTALL.md` (git clone, or the `.plugin` bundle in Cowork) and to run `verify-install.sh` from the install root to confirm the fix. Only proceed without the references if the user explicitly says to — and if they do, state clearly in your output that it was produced in degraded mode without the pack's reference material. ## Context Engineering onboarding is genuinely different from designer onboarding. The mental model is different (consuming an API vs composing with a library), the first tasks are different (install and import vs connect Figma library), the tooling is different (package manager, TypeScript types, test harness vs Figma, documentation platform). Most importantly, engineers are where component drift originates — wrapping system components in local styled wrappers, hardcoding toke...
