Good morning, it's Friday, October 9th, 2026, and this is your VS Code briefing.
The through-line today is control: who gets to enforce policy for AI agents, and how sessions survive it.
First, Agent Host is now the gatekeeper. Two linked changes, PR 340617 and PR 340529, require Agent Host when managed permissions or sandbox rules are non-empty, because local, Claude and Codex harnesses can't reliably enforce them. For developers that means enterprise-managed settings will effectively disable those…
Second, the Agents Window is getting more durable. Canvas tabs no longer disappear on session or chat switches in PR 340465, and extension canvases can now be opened from the Add Tab menu in PR 340575. Connected tabs got geometry and overflow fixes in PR 340635, and multi-session panels got consistent spacing in PR…
Third, the rich Markdown editor matured. PR 340505 adopts published language features for rename, completion and diagnostics, while PR 340695 adds native Outline and heading breadcrumbs without a second parser.
Also notable: commit 5042306 fixes a memory leak from language-model discovery after provider disposal.
