parallel coding sessions → changes reviewed by an employee.
Create workspaces
Each concurrent agent receives its own git worktree, branch and terminal.[Source 1]
Coordinate work
Employees move between agent sessions, review results and provide feedback.[Source 1]
Access and controls
No separate access-control assessment is recorded.
Reliability and validation
Not reported: The available sources do not describe how the team checks the output.
Adoption and operating evidence

Mux: 5,068 merged PRs across 461 repositories and 10 orgs
Key observation
Mux users show 3.5x more merged PRs per engineer than baseline (39.6 vs 11.4); the post cautions users may skew toward already-high-output engineers[Source 1]
Reported by
Coinbase
Scope
Merged pull requests per engineer for Mux users compared with a baseline of non-users

Lessons
Not reported: The available sources do not report lessons from this work.
Reported: Documented use example; no universal platform run is implied.
human involvement
Not applicable: There is no single platform-wide agent review boundary. Scoped downstream operating-model claims remain in research details; access controls are described separately.
Self-reported comparison whose own text cautions that Mux users likely skew toward engineers who were already high-output and AI-forward; no cohort method is documented.
