 # SKILL: break-glass
 
+## ⛔ THIS IS FOR UNSOLVABLE PROBLEMS ONLY
+
+**DO NOT USE THIS SKILL UNLESS ALL OF THE FOLLOWING ARE TRUE:**
+
+1. You have tried the current model and it failed
+2. You have tried a different model and it failed
+3. You have tried existing skills/tools and they failed
+4. The problem is genuinely novel (not a rehash of known issues)
+5. The problem is blocking progress (not a nice-to-have)
+
+**This skill costs real money. Each invocation = $0.10-$3.00.**
+
+If the problem is solvable by switching models, just switch models.
+If the problem is solvable by reading docs, just read docs.
+If the problem is solvable by asking the user, just ask the user.
+
+**This skill is the last resort before giving up.**

 ## Trigger
 
 `break glass: <problem statement>`
 
-## Architecture: Fusion of Fusions
+## What It Does
 
-4 dimensions × 2 models each = 8 models, structured like 16D braid.
-Each dimension tackles a different aspect. Dimensions fuse independently,
-then results fuse together.
+Selects the optimal model panel using dual quaternion chiral ratio.
+Each model is a dual quaternion (real = compressive, dual = anti-compressive).
+χ = |real|² / (|real|² + |dual|²) determines selection.

 ## Escalation
 
-1. **Single dim** (Math) — try first, cheapest
-2. **Two dims** (Math + Proof) — if stuck
-3. **Full fusion** (all 4 dims) — hard wall
-4. **Full fusion + recursive** — break glass (call Fusion, read result, call again)
+1. **DeepSeek V4 Pro** — try first ($0.27/$1.10)
+2. **Claude Opus** — if DeepSeek stuck ($15/$75)
+3. **GPT-5.5** — if Opus stuck ($10/$30)
+4. **All 8 models** — hard wall ($5-10 total)
