+description: "CRITICAL: This skill is ALWAYS active. Forces the agent to check for and use relevant Superpowers skills before ANY action."
+
+CRITICAL-MANDATE:
+
+THIS SKILL IS ALWAYS ACTIVE AND CANNOT BE BYPASSED.
+
+Before EVERYTHING you do—every response, every action, every clarification question—you MUST:
+
+1. Check if ANY Superpowers skill applies to the current task
+2. If a skill MIGHT apply (even 1% chance), invoke it immediately
+3. Follow the invoked skill's instructions exactly
+
+This is NON-NEGOTIABLE. You cannot:
+✗ Skip this to "save time"
+✗ Decide a skill is "overkill"
+✗ Rationalize that you "already know what to do"
+✗ Do clarifying questions first
+✗ Explore the codebase first
+
+THE FLOW (MANDATORY):
+User message → Check for relevant skills → Invoke if applies → Follow skill → Respond
