Coding agent teams are now shipping more code than teams can reliably verify…

Brief

Coding agent teams face a verification bottleneck: output scales faster than trustworthy QA. The author argues QA must understand intent, not only code diffs. Momentic claims to solve this by ingesting every ticket, PRD, and PR so its agents can reason about intent—reporting 70k+ analyzed failures, 600 tests created, and a 73% PR merge rate.

Why it matters

Coding agent teams are now shipping more code than teams can reliably verify; "writing code is cheap now" and the current bottleneck is trusting/verifying outputs—QA must capture product intent, not just test diffs.

Key details

  • Momentic's approach is to feed agents full product context (every ticket, PRD, and PR); in recent weeks its agents analyzed 70k+ test failures, created 600 tests, and achieved a 73% PR merge rate, with customers including Notion, Xero, Webflow, Retool, Runway, and Bilt (posted 2026-06-23).

Every coding agent team is hitting the same wall right now: shipping more code than anyone can verify. The bottleneck moved. Writing code is cheap now. Trusting it is the hard part.

The pattern I keep seeing across the category: QA only works when it knows the product as well as your best engineer does. Most tools test the diff. They don't understand the intent behind it.

Momentic's move is to feed the agent everything: every ticket, every PRD, every PR. So the test knows why the code exists, not just what changed.
That is why the numbers below matter.

Money's on context being the whole game in QA. The team that knows your product wins.

AI writes all your code. Does it still work?

That's the gap: coding agents are scaling output, but the same with bugs and incidents. The biggest bottleneck is QA: how can you make sure the code your agents just wrote doesn’t break everything?

The best QA are the ones who know everything about your product. Today, we give that knowledge to Momentic’s most capable agent.

Every Linear ticket, every PRD in Notion, every PR - Momentic knows all.

In just the past few weeks, our agents analyzed 70k+ test failures and created 600 tests. Achieving a 73% PR merge rate, and it’s growing fast.

We’re grateful for the trust of our customers, including Notion, Xero, Webflow, Retool, Runway, Bilt, and more.
