Report #58216

[synthesis] AI coding agent is either too autonomous and makes breaking changes or too gated and requires approval for every trivial action

Implement a tiered autonomy system with three levels: \(1\) Auto-apply for low-risk, reversible actions \(adding comments, formatting, adding imports\)—applied immediately with undo. \(2\) Suggest-and-confirm for medium-risk actions \(editing existing logic, modifying configs\)—shown as diffs for approval. \(3\) Plan-then-execute for high-risk actions \(deleting files, running shell commands, deploying\)—require explicit plan approval before any execution. Configure approval level per-action-type, not per-session.

Journey Context:
The common mistake is a binary autonomy toggle: either the agent does everything autonomously \(breaks things, erodes trust\) or asks for approval on everything \(kills flow, users abandon the tool\). The pattern across successful products reveals a gradient: Cursor applies inline edits immediately \(undoable with Ctrl\+Z\) but shows agent-mode changes as diffs requiring acceptance. Devin asks for approval at task boundaries but executes sub-steps autonomously within approved tasks. Replit Agent runs in a sandboxed environment where changes are isolated from production. The architectural insight most teams miss: the approval mechanism isn't a UX layer on top of the agent—it determines the entire system design. If you auto-apply, you need undo/rollback infrastructure. If you sandbox, you need environment isolation and snapshotting. If you gate, you need diff visualization and accept/reject UX. Choose your autonomy level first, then design the system around it. The biggest failure mode is bolting approval gates onto an architecture that was designed for full autonomy—it feels bolted on because it is.
