PRGuard for SRE & QA
Most incidents aren’t caused by the deploy process. They’re caused by the change that merged three weeks earlier — the missing retry, the swallowed exception, the “temporary” handler with no error path.
PRGuard enforces the reliability standards you already ask for in review — on every pull request and push, written in plain language, applied every single time.
Without PRGuard
The action item says “all external calls must have timeouts and retries.” It lives in a runbook. Whether the next PR honours it depends on who reviews it, at what hour, under what deadline.
With PRGuard
The action item becomes a rule. Every change is audited against it — automatically, consistently, including the hotfix pushed straight to main at 2am. The lesson stays learned.
Idempotency & error handling
“Retried jobs must be idempotent.” “No bare excepts — failures must be logged with context.” Write the patterns your on-call rota depends on, and have every change judged against them semantically, not by string-match.
Test coverage expectations
Require that behaviour changes arrive with tests, and that failure paths are covered — not as a coverage percentage to game, but as a standard the audit checks the change against.
Pushes audited too
The riskiest change is often the one that skipped the PR. PRGuard audits direct pushes as well as pull requests, so the emergency fix gets the same scrutiny as the planned one.
Finding to fix, on the record
Each finding is tracked from first flag to approved fix to the re-audit that closes it — so “did we actually address it?” has an answer you can look up, not a thread you have to find.
Yes — that’s the core use case. Write the action item as a plain-language rule (“all external calls must have timeouts and retries”) and every subsequent change is audited against it.
The lesson stops depending on reviewers remembering the incident.
They’re audited exactly like pull requests — the 2am emergency fix gets the same scrutiny as the planned change.
Skip markers can exempt a change, but they’re off until you enable them per repository, so an exemption is a policy decision you made.
No — percentage gates get gamed. You write coverage expectations as standards (“behaviour changes arrive with tests”, “failure paths are covered”) and each change is judged against them semantically.
Keep your coverage tooling for the number; PRGuard checks the intent.
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.
