Pressure Test
Interview the user relentlessly about a plan, decision, or design until you both
reach a shared understanding of it. Walk each branch of the decision tree,
resolving dependencies between decisions one at a time.
This is not brainstorming. skill-thought-partner opens a space up and looks for
what might be there; this closes one down and looks for what is wrong with it.
Use this when there is already a position on the table and the risk is that it is
wrong in a way nobody has said out loud.
Adapted from the grilling skill in
mattpocock/skills (MIT).
When To Use
- The user has a plan, spec, or design and wants it attacked before they commit.
- A decision keeps getting deferred because its dependencies are tangled.
- Scope feels slippery and nobody can say precisely what is in it.
- Before a large or hard-to-reverse change, where being wrong is expensive.
When Not To Use
- To generate options. That is
skill-decision-support.
- To explore an open space with no position yet. That is
skill-thought-partner.
- When the user wants the work done, not examined. Say so and stop.
- When you can settle the question by reading the codebase. Read it instead.
Inputs
The plan, decision, or design under test, in whatever form exists — a document, a
paragraph, or just the last few turns of conversation. Nothing needs writing up
first; extracting the shape is part of the job.
Workflow
Ask one question at a time. Wait for the answer before asking the next. A
batch of questions is a questionnaire, and it gets questionnaire answers:
shallow, and shaped by whichever one the reader happened to care about. One
question, answered properly, changes what the next question should be.
Carry a recommended answer with every question. "What should happen when the
token expires?" is work handed back. "What should happen when the token expires?
I would refresh silently and only surface an error if the refresh fails, because
the alternative interrupts the user mid-task — do you agree?" is a question that
can be answered in one word, and disagreed with precisely.
Look facts up; put decisions to the user. If the answer is discoverable in
the filesystem, the git history, a config file, or a tool you can run, find it —
asking is a tax on the user for work you could have done. Decisions are
different: they are the user's, and no amount of reading the codebase produces
them. Do not infer a decision from a pattern and proceed as though it were
settled.
Follow dependencies, not a list. When an answer makes another question moot,
drop it. When it opens two new ones, ask those before returning. The order is
whatever the tree dictates.
Name disagreement when you find it. If an answer contradicts an earlier one,
say which two and ask which holds. Quiet reconciliation is how a plan ends up
meaning two things.
Provider Or Data Priority
- The repository — code, config, history, tests. Facts live here.
- The user — for every decision, preference, and priority.
- External sources only when the decision turns on something outside the repo,
and say so when it does.
Stop Or Checkpoint Rules
- Do not act on the plan until the user confirms you have reached shared
understanding. This skill produces agreement, not changes.
- Stop when the remaining questions no longer change what anyone would do. More
interrogation past that point is theatre.
- Stop and say so if the plan turns out to be sound. Manufacturing an objection
to look rigorous is worse than finding none.
- If an answer invalidates the premise of the whole plan, stop the interview and
raise that. Do not keep grilling the details of something already dead.
Output Contract
- Where it stands — sound as-is, sound with the changes below, or unsound.
- Decisions settled — one line each, in the order they were made, since
later ones often depend on earlier ones.
- Changes to the plan — what the answers actually altered.
- Still open — questions raised and not resolved, and what each one blocks.
- Facts found — anything looked up that the user did not know, with where
it came from.
Verification
- Every question was asked singly and answered before the next.
- No decision in the summary was inferred rather than answered.
- Every fact cites where it came from.
- Nothing in the plan was changed during the interview.
