Step 0: Verify Dependencies

This skill invokes four external skills plus one Claude Code built-in. Before doing anything else, verify each is installed at ~/.claude/skills/<name>/SKILL.md (or as a built-in). simplify is a Claude Code built-in command and does not require installation.

Check each path in a single shell call:

for s in vercel-react-best-practices applying-solid-principles security-review code-slop; do
  [ -f ~/.claude/skills/$s/SKILL.md ] && echo "OK  $s" || echo "MISS $s"
done

If any report MISS, stop and tell the user which skills are missing with the exact install command for each. Do not proceed until the user confirms they are installed.
