Verify

“Done” is a claim, not a fact

Someone — a developer, a contractor, or an AI agent — says the work is finished. Verification is the cheap step that finds out whether that is true before it reaches your customers.

What is in this category

Ways to check somebody else’s work

Including work produced by an AI, which tends to look finished long before it is.

Verify against requirements

Line by line: what was asked for, what exists, and what quietly did not get built.

Independent second reading

A different model, with no knowledge of how the work was written, reviewing it adversarially. Shared blind spots are the ones that survive a self-review.

Regression risk analysis

What else this change can break, and which of it is covered by a test that would actually fail.

Pre-deploy review

The last look before it goes out: what is in this release, what is risky, and what to watch after it lands.

Post-deploy verification

Whether it actually works in production, judged against what you decided beforehand rather than what looks fine now.

Migration verification

Whether the data arrived intact, including the rows nobody thought to check.

How verification runs

  1. The claim is stated first

    What is being verified, in one sentence. Vague scope produces vague verification.

  2. The reviewer does not see the reasoning

    An independent reading is only independent if it does not inherit the author’s explanation of why the code is correct.

  3. Every finding must be reproducible

    Concrete inputs, concrete wrong output. A finding nobody can reproduce is noise.

  4. A verdict, not a mood

    The result ends with an explicit judgement and the findings ranked, so you know whether to ship.

When verification pays for itself

Skip it if

You wrote it and you understand every line

The change is cosmetic and reversible in a click

A failure would cost you nothing at all

Do it if

An AI agent wrote most of it

A contractor is asking to be paid for it

It touches money, auth or customer data

You cannot personally judge whether it is right
