Agent systems that
check their own work.

An agent does the task. A mechanical gate refuses to pass output that breaks your rules — before a person ever sees it.

Most teams that tried AI got the first half. The drafting got faster, and then someone had to read everything anyway, so the time saving disappeared. The missing half was never a better model. It was that nothing checked the output.

What a gate actually is

Software that says no.

Not a prompt asking the model to be careful. A separate program that reads the output, compares it to your rules, and exits with an error when it does not comply. Below is a real one, running against a live storefront: it blocks any claim that contradicts the product's source-of-truth document.

# the copy an agent wanted to publish
$ python check_claims.py "clinically proven to cure back pain"

  [MEDICAL CLAIM]  'cure'
  [MEDICAL CLAIM]  'pain'
  [UNSUBSTANTIATED] 'clinically proven'

  TOTAL ISSUES: 8
  exit 1 — not published

# the same check, on approved copy
$ python check_claims.py --live

  PASS  /  PASS  /products  PASS  /pages/about
  TOTAL ISSUES: 0

The point is not the vocabulary list. It is that the decision is not left to the model. The same pattern gates ad creative against its brief, blocks a session from closing while the system is in a broken state, and stops a number from drifting between one page and the next.

Where it fits

Anywhere a person is re-reading machine output.

Client-facing copy

Claims checked against an approved facts document before anything is scheduled or published.

Creative at volume

Every cut checked against the brief — length, structure, banned phrasing — so the weak ones never reach review.

Reporting

Numbers pulled and verified from the source, never restated from a model's recollection.

Anything repetitive

If a person checks the same thing daily against the same rules, that check can be a program.

How it goes

Small, and provable.

You name the step

The one place where checking machine output eats real hours.

I write back honestly

A short note on whether a gate would fix it. Free, and sometimes the answer is no.

One workflow, built

The agent, plus the gate that governs it, running on your rules.

Monthly after that

Maintenance, tuning as your rules change, one new workflow a month.

Tell me the step.

If checking AI output is costing your team hours somewhere, describe that one step. I will send back a written assessment of whether a verification gate would actually fix it — no call required, and no charge either way.

Describe the step

If a gate would not help, I will tell you that instead.
