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

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.
Rosentic comments on the PR the moment it finds a cross-branch break: the exact change, the stale caller, and whether it would fail.
Tested across 500+ real-world repositories. 13 languages, 131 regression fixtures.
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.
Each pull request is checked against every active sibling branch before merge, and gets a PASS or FAIL bound to that branch's true head commit. Policy you set per repo or org-wide drives the verdict: gate mode, severity threshold, per-layer enforcement, and branch rules like always-block on release/*. Every verdict records the policy version in force, so an auditor can answer what the rule was, not just what the answer was. Run it advisory to start, or make it a required check in two clicks. If the check cannot run, it tells you. It never passes silently.
An append-only ledger records every verdict: what was checked against what, at which commits, under which policy version, with a fingerprint that lets anyone replay the check and get the same answer. Because the engine is deterministic, the record is reproducible. Export it as JSON or CSV. This is what lets a team stop re-reviewing agent code by hand.
See which agents hold which branches across your repos, with confidence-ranked attribution, and which agent pairs are currently diverging against each other. When you run several agents in parallel, this is the picture almost no team can otherwise assemble.
Illustrative. Real attribution comes from your own branch history.
The Rosentic MCP server puts the check inside the loop: agents validate a file before writing it, in under 100ms, and can look up any past verdict. Works with Claude Code, Cursor, Codex and six more editors.
Analysis runs where your code already lives. Source is parsed locally and never transmitted, at any tier. What travels off your runner is your choice, and it is exact per tier.
