Pressure Test

Stress-tests a feature idea against constraints, users, and your existing system in one pass. Verdict: kill or proceed with conditions. No building required.

How It Works

Pressure Test · Workflow
Three adversarial passes, then a kill-or-proceed verdict.
TriggerPlan, idea, or decision · A spec, PR, strategy memo — anything you're attached to
1
Premortem
It failed 6 months out — name the false assumption that killed it
2
Blind spots
Cynical competitor view — how they'd exploit the weaknesses
3
Risk ranking
Top 3 risks scored likelihood × impact, each with a contingency
Verdict + top 3 changes · Survivability call · load-bearing assumption · fix before proceeding

Use Cases

  • Kill a bad feature idea before writing a single line of code
  • Stress-test a proposed addition against your existing system constraints
  • Get a structured kill/proceed verdict before writing a PRD

The Problem

You have an idea. It feels right. You build it. Six hours later you realize it doesn't fit the system, solves a problem no one actually has, or creates three new ones. The time to find this out is before the first commit — not after the first PR review.

What It Does

  1. 1
    Define the idea precisely

    One sentence: who, what, why now. If you can't write this sentence, the idea isn't ready. This is a hard gate — a vague idea produces a useless verdict.

  2. 2
    Constraints check

    Does it fit your stack, your scale, your existing data model, your deployment constraints? List every constraint violation explicitly.

  3. 3
    User evidence check

    Who specifically wants this — name them. What do they do instead today? "Someone would want this" is not a user. If you can't name a person and describe their current workaround, this check fails.

  4. 4
    Integration risk check

    What breaks if you add this? What does it conflict with? What new dependencies does it introduce? Be specific — "it might cause issues" is not an integration risk.

  5. 5
    Kill / proceed verdict

    Explicit reasoning for each check. Kill if any check fails without a clear mitigation. Proceed with conditions if all checks pass — list the conditions. The kill verdict is the success case.

What You Get / What It Doesn't Do

What you get
  • Kill / Proceed verdict with explicit reasons for each check
  • Constraint violations listed with severity
  • Specific user evidence (or documented lack thereof)
  • Integration risks identified with affected components
  • Conditions that would flip the verdict from kill to proceed
What it doesn't do
  • Build the feature
  • Validate with real users
  • Write a PRD — use /prd-writer for that
  • Make product decisions — it surfaces the evidence, you decide

Tips

The kill verdict is the win

You saved yourself from building something wrong. A kill verdict in 10 minutes is worth more than a week of wasted implementation.

Name the user, describe the workaround

"Someone would want this" is not user evidence. Name a specific person and describe exactly what they do today instead. If you can't, the user evidence check fails.

Write the PRD immediately if it passes

If the idea survives all five checks, use /prd-writer right away. The reasoning is still fresh and maps directly to acceptance criteria.
