PRGuard for engineers

Feedback in Minutes,
Not Meetings.

Q: Will PRGuard flood my pull requests with nitpicks?

No. PRGuard only enforces standards your team wrote — there is no generic rule catalog behind it. Every finding is tied to a written rule your team chose to enforce, so if something is noise, the fix is editing the rule, not muting a scanner.

The slowest part of shipping isn’t writing the code — it’s waiting for someone to review it.

PRGuard reads every pull request and push against your team’s written standards and posts a review in minutes: specific findings, on specific lines, with the reasoning spelled out.

It comments — and when it thinks it can fix a finding, it offers the fix. Nothing lands without your approval.

What You Get on Every Change.

Fast, specific feedback

A review that’s there before your coffee is.

Minutes after you push, findings land on the lines they’re about — what’s wrong, why it matters, and which of your team’s standards it breaks.

No waiting for a reviewer’s calendar to clear before you find out.

Drift caught early

Architectural drift, flagged the moment it starts.

The shortcut that bypasses the service layer, the query that belongs in a selector, the pattern your team agreed to retire — caught in the change that introduces it, not in the rewrite six months later.

Fixes on request

When you want the fix, ask for it.

Where PRGuard thinks a finding is fixable, it offers an AI-drafted fix — on request, per finding. On a PR audit it lands onto your PR’s own branch for you to review like any other commit.

Nothing is committed on your behalf without your say-so.

What a Finding Looks Like.

Line-level, explained, and tied to a written standard — feedback you can act on without a follow-up meeting.

Payments

Details

billing/webhooks.py:14

A retried webhook charges the customer twice. Stripe redelivers events after timeouts, and nothing here records what has already been processed.

Non-idempotent payment handler: in handle_webhook(), the charge is written at line 14 without checking ProcessedEvent. Because event.id is never recorded, a redelivered event re-executes the whole charge path — violating your rule that payment webhook handlers must be idempotent.

Copy

Replace the direct charge write in handle_webhook() with a guard: ProcessedEvent.objects.get_or_create(stripe_id=event.id), returning early when the event was already processed.

In billing/webhooks.py, make handle_webhook() idempotent: before any processing, guard with ProcessedEvent.objects.get_or_create(stripe_id=event.id) and return HTTP 200 immediately when the event was already processed. Do not change the charge logic itself.

  def handle_webhook(request):
      event = _verified_event(request)
+     _, created = ProcessedEvent.objects.get_or_create(
+         stripe_id=event.id)
+     if not created:
+         return HttpResponse(status=200)
      charge = _record_charge(event)
      return HttpResponse(status=200)

Unassigned Assign

Illustrative example. Findings are advisory by default — a person approves every fix before it lands.

Not another noisy linter. PRGuard doesn’t run a generic rule catalog — it enforces the standards your team wrote, in plain language, judged semantically on each change. Rules your team never wrote can’t generate noise, and the ones it did write are ones you actually care about.

Will PRGuard flood my pull requests with nitpicks?

It only enforces standards your team wrote — there is no generic rule catalog behind it.

Can PRGuard commit code to my branch without asking?

No. Where PRGuard thinks a finding is fixable it offers an AI-drafted fix, and nothing happens until you request it.

On a PR audit the fix lands on your PR’s own branch as a commit you review and approve like any other.

Do direct pushes get reviewed too, or just pull requests?

Both. Pushes are audited the same way pull requests are, so a commit straight to main gets the same feedback.

Skip markers exist for changes that genuinely don’t need review, but they’re off until your team enables them per repository.

The AI credits are included.

AI usage is part of your subscription, not a bill on the side. Every plan includes a set monthly AI credit allowance, and each audit draws from it — no separate API key to bring, no separate token invoice. And if a busy month needs more, top-up credits are available anytime and roll over.
