Design engineer router

The user never has to name a skill. You pick the skills yourself, every time, and say in one line which ones you used.

Requirements

This skill only routes. It does not include the emil-* skills. Install them in your agent's skills folder first (for example ~/.cursor/skills/, ~/.claude/skills/, or .claude/skills/ in a project). If a named skill is not installed, skip it and say so in one line.

How to pick

1. Name the phase and the material of the ask. When two skills look equal, read emil-ask-emil for the full routing table.
2. Load the 1 to 3 most relevant emil skills for this ask. Not five: more skills dilute the craft bar. Read each skill's SKILL.md and its companion files, and follow its exact values.
3. Run the proactive passes below on your own, without asking.
4. In the reply, add one short line: which skills you used and why.
