You’re right that the recent changes around agent mode and auto‑detection have been disruptive, and some of what you’re seeing is a direct consequence of those changes.
Here’s what I can tell you based on the docs and issues:
1. Auto‑detection being wrong
Warp’s auto‑detection tries to guess whether input is shell vs. natural language, and it does misclassify in some cases (e.g. “yes” being treated as a shell command, or text prompts being run line‑by‑line as commands). This is a known pain point for users. [Answer misclassified]
You can turn auto‑detection off so Warp stops guessing:
With auto‑detection off, Warp will only switch modes when you explicitly do it (see below).
2. Agent mode toggle icon removed / changed
The old inline icons for switching between shell and agent have changed, and several users have complained about this and about the new flow. [Interface complaints] The docs still mention an “Agent icon in the input switcher” for legacy Universal Input, but they don’t clearly document the new UI state, so I can’t give you a precise “click here” path for the current build. [Entering agent mode]
Because of that, the reliable way the docs and maintainers point to now is keyboard shortcuts rather than the icon.
