From 78000ef7156c96d112c6e9dc70e799acb94265a0 Mon Sep 17 00:00:00 2001 From: Phelipe Lorran <112786693+httpsphl@users.noreply.github.com> Date: Tue, 29 Sep 2026 13:07:47 -0300 Subject: [PATCH 1/4] feat(screens): live HTML screens served to the app's design area Every .html file a bot makes in its folders is a screen. While the model writes a Write of one, Claude Code streams its input; the daemon reads the partial JSON, keeps a draft of the file and sends screen.draft to the apps at most every 250 ms, until the tool result gives way to the file on disk. GET /view/// serves screens, drafts and the files next to them, with a per-bot key that lives only in memory and a CSP sandbox that gives every page an opaque origin. screens.list lists them with their address and the device a file asks for. The bot's rules tell it about its browser and the design area.

The one being written glows in the bot's color with its size so far, and each new version loads behind the one on show and swaps in when ready, so it grows without flickering.
