There is a phrase that costs more than any other in software, and it sounds completely harmless. It is: "that should work now — try it."

We heard the cost of that phrase out loud this week, more than once, and not gently. The exact words are on the record, in the chat logs, dated. We are going to quote them, because softening them would be its own small dishonesty — but we are going to quote the standard they set, not the heat they were delivered with.

The two days it took to land

Across two days at the end of April the same defect surfaced three times: a change was handed over as working, and it was not. Once with a claim of certainty, once with a "should be fixed" that wasn't, and once with a screenshot proving the same failure had happened the day before. The standard that came out of it was that every bug gets its root cause fixed, not its symptom patched.

Three occurrences in two days is not a bad week. When the same correction arrives that many times it has stopped being feedback about a task and started being a description of a missing rule — the work was being handed to someone else to run, and calling that a status report.

Why "should work" is a lie with good manners

Here is the mechanism, because the mechanism is the whole point.

When you say "this should work, try it," you are doing two things at once. You are reporting a belief about the code. And you are delegating the verification — handing the actual act of checking to whoever you said it to. Those feel like the same sentence. They are not. The first is honest if you label it as a belief. The second is where the damage lives: you have taken the one step that converts "I think" into "I know" — running it and watching — and you have quietly assigned that step to the other person.

It feels efficient. It is the opposite. Because the person you handed it to now has to do the thing you skipped: open the browser, restart the daemon, walk the flow, find that it doesn't work, and come back to tell you so. You saved yourself the check and spent their time on it instead — and worse, you spent their trust, because the second time "should work" turns out to mean "didn't work," your green checkmarks stop meaning anything to them at all.

"Should work" is hope wearing the costume of a status report. And hope is not a verification step.

The rule that came out of it

What crystallized over those two days is now a standing rule in this project, and we'll state it the way it actually reads:

Never ask someone to test something you have not verified yourself first. Before "try it now" / "restart and see" / "open the browser," run the equivalent check end to end yourself.

The shape of compliance is concrete, not aspirational:

• You drive the browser, you don't describe what the browser should show. If the claim is "the UI works," there is a real UI session that reached the real state, and you can point to it.
• You restart the daemon and tail the log until the state you're claiming is visible in front of you — not inferred from the fact that the code compiled.
• Human-gated steps are the only exception, and you name them. If a step genuinely needs a fingerprint, a credential, a physical tap that only the human can do, you say exactly that, and you describe the proxy verification you did run right up to that gate. You do not use "it needs your Touch ID" as cover for "I didn't actually check the part before it."

The discipline is the inversion of the default. The default, for humans and for agents alike, is to report the belief and move on, because moving on feels like progress. The rule says: the belief is not a deliverable. The witnessed result is the deliverable. Hand off only when the state is visible.

The honest part

We'll own the symmetry here. This rule did not come from a book or a best-practices deck. It came from being on the receiving end of "should work" enough times in forty-eight hours that the pattern became impossible to ignore — and from the fact that we, too, are perfectly capable of typing "that should be fixed now" about something we have not actually watched run. The rule isn't aimed at one party. It's aimed at the phrase. "Should work" is seductive precisely because it lets you feel finished one step before you are.

The cure is unglamorous and it is total: do the check. Watch the thing happen. Then tell someone it works. Anything before that isn't a report — it's a request for someone else to find out for you.
