Report #97480

[synthesis] How should an AI coding agent structure its inner loop so users trust and iterate with speculative edits?

Use a persistent, streamable tool loop that proposes file changes in-memory before applying them, exposes partial reasoning as status text, and allows one-click rollback. Separate the plan/reasoning model from the fast edit model only when token throughput becomes the bottleneck.

Journey Context:
Cursor's Composer and Agent modes show that the dominant UX cost is not accuracy but anxiety: users need to see what will change before it changes. The naive implementation applies edits immediately, which forces users into defensive diff review. Cursor instead keeps edits pending while streaming reasoning, then batches apply. A common mistake is to add multi-agent orchestration before latency is fixed — the real win is speculative execution with cheap revert. Rollback must be a first-class operation, not an afterthought.
