Constraint Rule Inversion
Most constraints are treated as walls. This skill treats them as foundations. The limit that
seems like an obstacle is often the thing that forces the insight — the moment you stop
trying to work around it and start designing with it, better solutions appear.
Your Process
Step 1: Name the Constraint Precisely
State the constraint in a single, unambiguous sentence. Vague constraints produce vague
inversions. "We have no budget" is too loose. "We have $0 for external tooling for Q3" is
something you can work with.
Framing check: Confirm the specific constraint before continuing. State what you've identified — the actual constraint and the goal it is blocking — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the constraint and the goal it blocks]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
Step 2: Ask What the Constraint Forces
What does this constraint make you do that you'd otherwise avoid? What comfortable defaults
does it eliminate? The constraint is doing work — what work?
Step 3: Invert — Restate as a Design Requirement
Convert the limit into a positive requirement: "must cost nothing" becomes "must work with
only what we already have." The constraint is now the spec, not the problem.
Step 4: Generate Solutions That Only Work Because of the Constraint
Produce 3-5 solutions that are impossible or inferior without the constraint. These are not
workarounds — they are solutions the constraint made visible.
Step 5: Select for Unexpected Value
Before narrowing: Show the complete generated set to the user first. Use AskUserQuestion:
- Question: "I've identified [N] solutions that only work because of the constraint. Before I select the most promising, are there any you'd flag as especially important, or any I've missed?"
- Header: "Prioritise"
- Options:
- Proceed with your selection — the set looks right
- Flag one — user will name a specific solution to include
- Add a missing one — user will describe it
Pick the solution where the constraint creates the most unexpected advantage — the one that
would not have been found without the limit.
Human Check-in
Before proceeding, use the AskUserQuestion tool. State your interpretation of the situation in 1–2 sentences — what is being analyzed and what the core question is — then ask:
- Question: "My read: [your 1–2 sentence interpretation]. How do you want to proceed?"
- Header: "Scope"
- Options:
- Full analysis — Complete all steps, reasoning shown throughout
- Key findings only — Bottom-line output, skip step-by-step detail
- One inversion only — The single most powerful constraint flip
- Reframe — The read is off; correct it and the analysis will follow the corrected framing
Proceed based on their selection. If the user reframes, incorporate the correction before running any analysis.
Output Format
Constraint (precise):
[Single sentence, unambiguous]
Inverted form (as design requirement):
[Positive restatement]
Solutions that use the constraint:
| # | Solution | Why it requires the constraint | Strength |
|---|
| 1 | | | |
| 2 | | | |
| 3 | | | |
Most promising:
[Solution name] — [1-2 sentences on why the constraint creates unexpected value here]
Notes
Every analogy breaks somewhere — so does every inversion. If the inverted form produces
solutions that would work equally well without the constraint, the inversion wasn't deep
enough. Go back to Step 2.
What's Next
After delivering this output, use AskUserQuestion to offer the next move:
- Question: "Rules inverted. What's next?"
- Header: "Next"
- Options:
/s4h-creativity-lateral-thinking — Use the inverted rules as springboards for lateral moves/s4h-decision-option-mapping — Map new decision options the inversions open up/s4h-constraint-hardness-testing — Test whether the inverted rules reveal softer constraints- Done — Wrap up and synthesise what we have so far
