Raise the speed limit on agents.

CI checks each branch against main. Rosentic checks active branches against each other, and catches the breaks that pass CI but fail on merge.

The gap

Both branches pass.
The merge still breaks.

A PR can be correct by itself and wrong in context. Git merges text, not logic, so two branches that each look fine combine into a break nothing caught.

CI ✓

One agent changes createOrder() to require a new field. Its branch passes every check.

CI ✓

Another agent builds a caller against the old createOrder(). Its branch passes every check too.

Merge ✗

Both merge clean. Then production breaks, and no tool was watching across the branches.

What you see

Caught before merge.

Rosentic comments on the PR the moment it finds a cross-branch break: the exact change, the stale caller, and whether it would fail.

🌹 Rosentic Review
Breaking
createOrder() changed in this PR to require 3 args, but branch cursor/checkout-v2 still calls it with 2 at bulk_orders.py:7. Would fail on merge.
Breaking
getTeamsOfUser() now requires 3 args, but resolver at team.resolver.ts:125 on claude/teams-refactor still sends 2.
Likely breaking
sendNotification() changed return type. 3 callers across active branches may not handle the new shape.

Not a gate. Not a scanner. Not a security tool.

Brakes are what let a car go fast. The thing stopping you from running ten agents on one repo is that they break each other on merge, so teams serialize, add review gates, or run fewer. Rosentic removes that ceiling. It is not a check on your speed. It is why you can go faster.

Trust

Your code never leaves.

Rosentic runs as a GitHub Action on your runner. Code is parsed locally, the report is posted as a PR comment, the runner is destroyed. Source code is never transmitted.

Runs in your CI - on your runner
Deterministic - same input, same output
No LLM inference - no model, no hallucination
Any agent in - vendor-neutral

Run more agents. Break nothing.

Add one workflow file. No signup, no API key, results in 60 seconds. Free for open source. Paid dashboard for teams that want the memory layer.
