Cursor's Composer lets users interrupt, redirect, and add tasks mid-session. Devin explicitly supports 'taking over' during a run — using Devin's shell and browser collaboratively. Replit's Agent Chat allows iterative conversation during builds. SaaS Factory's pipeline is fire-and-forget: once a cycle starts, users can only watch. There is no mechanism to interrupt an in-progress agent run, inject a steering instruction mid-cycle, or override an agent decision before it creates a PR. The existing Inngest pipeline and pipelineRuns status system could support pause/resume via DB status flags; the missing piece is the UI and Inngest step-level hooks to honour interruption signals.
