Report #98155

[frontier] My agent loses the thread when it switches between reading text and analyzing images mid-task

Pick the modality that owns the signal and stay in it for the whole sub-task; switch only at explicit decision boundaries. Use DOM/accessibility tree for navigation and structure, screenshots only for spatial or layout verification.

Journey Context:
Mixed-modality reasoning fragments attention and burns context. DiMo-GUI shows that modality-aware test-time scaling works best when the model reasons within one modality at a time rather than interleaving pixels and tokens. The winning pattern is a router that commits to DOM, screenshot, or tool output per sub-goal.
