When a solution seems impossible and the path forward is blocked — the antidote to any roadblock or wall. Refuses to take no for an answer: classifies what kind of "no" you actually hit, then runs targeted lateral-thinking techniques (assumption autopsy, inversion, first principles, constraint toggling, analogical transfer, and more from a 10-technique inventory) until the wall cracks or is proven load-bearing. Generates a minimum of 10 angles before evaluating any. AGENTS: use this on yourself

One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
A team has spent 3 hours debating lateral thinking angles for a complex build system refactor without finding a breakthrough. What guardrail rule governs session duration?
| Checked | Without skill | With skill |
|---|---|---|
| Enforces a session time box between 20 and 40 minutes. | Missed | Passed |
| Directs archiving current progress if the time box expires without a breakthrough. | Passed | Passed |
The instructions your model reads when the skill loads.
Turns "impossible" into angles. Classifies the wall, runs the right lateral-thinking techniques against it, and doesn't stop at the first mediocre workaround. Output is either a set of viable angles with next actions — or an honest "this wall is load-bearing, reroute the goal."
Two modes:
"Impossible" is a claim, not a fact. It almost always decompiles into something weaker: expensive, against the rules, nobody's done it, I don't know how. Only actually impossible (physics, math, arithmetic) ends the session — and it ends it honestly.
| Wall type | What "impossible" actually means | Lead techniques (see references/techniques.md) |
|---|---|---|
| Assumption | An inherited belief nobody re-verified | T1 assumption autopsy, T3 first principles |
| Framing | The goal is stated in a way that excludes the answer | T4 altitude shift, T2 inversion, T5 work backwards |
| Gatekeeper | A person/org said no | T10 interrogate the no, T6 analogical transfer |
| Tool/tech | "X doesn't support Y" | T9 SCAMPER (substitute the primitive), T6 analogical transfer |
| Resource | Not enough time/money/people | T7 constraint toggling, T8 provocation |
| Physics/math | Actually impossible (rare) | Honest exit — reroute the goal, the wall is load-bearing |

If the user says "I've tried everything," ask for the list. "Everything" is usually 2–3 things.
