Constraint Hardness Testing
Organisations accumulate phantom constraints — rules that were real once and calcified, or
beliefs that were never tested, or someone's preference that got repeated until it sounded
like policy. This skill separates genuine limits from assumed ones before any energy is
spent working around or accepting them.
Your Process
Step 1: State the Constraint
Write it exactly as it's been stated or assumed. Don't clean it up — the imprecision is
often where the phantom lives.
Framing check: Confirm the specific constraint and the goal it is blocking before continuing. State what you've identified — the exact constraint as you understand it and the goal or action it prevents — 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: Source It
Who said this constraint exists? When? Is the source a law or regulation, a signed contract,
a technical impossibility, a leadership decision, a team preference, or unknown? The source
determines the hardness ceiling.
Step 3: Consequence Test
What actually happens if this constraint is violated? State the consequence concretely. If
the answer is "I'm not sure" or "someone would be unhappy," the constraint is not hard.
Distinguish real consequences (fine, contract breach, system failure) from assumed ones
(pushback, awkwardness, political cost).
Step 4: Precedent Check
Has anyone tried to change or violate this constraint before? What happened? No precedent
often means no one has tested it — not that it can't be changed.
Step 5: Conditions Test
Under what circumstances would this constraint not apply? A truly hard constraint has no
exceptions. If you can find a scenario where it wouldn't hold, the constraint is softer
than stated.
Step 6: Classify
- Hard: real source, concrete consequence, no exceptions, precedent confirms
- Soft: real but negotiable, consequence is political or preferential
- Assumed: no clear source, untested consequence
- Outdated: was once hard, circumstances have changed
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
- Real vs assumed verdict only — Classify each constraint without full analysis
- 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 as stated:
[Exact wording]
Source: [Law/contract/technical/decision/preference/unknown] — [specific origin]
Consequence if violated:
[Concrete statement] — Real / Assumed
Precedent: [What happened when tested, or "untested"]
Conditions where it wouldn't apply:
[If any]
Classification: Hard / Soft / Assumed / Outdated
Recommended action:
| Classification | Action |
|---|
| Hard | Accept — design around it |
| Soft | Negotiate explicitly |
| Assumed | Test it — ask the source directly |
| Outdated | Challenge it — propose removal |
Notes
The most dangerous class is Assumed, because it looks like Hard. Before accepting any
constraint that cannot be sourced precisely, treat it as Assumed and test it — the cost of
testing is almost always lower than the cost of a permanent workaround.
What's Next
After delivering this output, use AskUserQuestion to offer the next move:
- Question: "Constraints tested. What's next?"
- Header: "Next"
- Options:
