xdg-portal - XDG Desktop Portal Infrastructure
Overview
Provides XDG Desktop Portal support for Sway containers. Installs the portal daemon, the wlroots-specific backend (xdg-desktop-portal-wlr), and the GTK fallback backend. Enables screen sharing, screenshots via portal API, and file dialogs for applications running inside the container.
Layer Definition
requires:
- dbus
- sway
- pipewire
env:
XDG_CURRENT_DESKTOP: "sway"
rpm:
packages:
- xdg-desktop-portal
- xdg-desktop-portal-wlr
- xdg-desktop-portal-gtk
- slurp
Key Properties
| Property | Value |
|----------|-------|
| Depends | dbus, sway, pipewire |
| Packages | xdg-desktop-portal, xdg-desktop-portal-wlr, xdg-desktop-portal-gtk, slurp |
| Env | XDG_CURRENT_DESKTOP=sway |
| Service | None (D-Bus activation on demand) |
| Ports | None |
How It Works
- D-Bus activation: Portal daemons start on-demand when an application calls a portal D-Bus method. No supervisord service needed.
- Sway config drop-in: Installs
~/.config/sway/config.d/portal.confwhich runsdbus-update-activation-environmentto exportWAYLAND_DISPLAY,XDG_RUNTIME_DIR,XDG_CURRENT_DESKTOP, andSWAYSOCKto the D-Bus activation environment. Without this, portal daemons can't find the Wayland display. - Auto-approve config: Installs
~/.config/xdg-desktop-portal-wlr/configwithchooser_type=nonefor headless automation (no user dialog for screen sharing).

Claude Code multi-agent support in Overthink — sub-agents, dynamic workflows, and agent teams, and how each drives the existing `ov eval` disposable beds to test and verify. MUST be invoked before authoring or invoking an ov sub-agent / dynamic workflow / agent team, wiring agent-lifecycle hooks, or asking "which primitive should drive the R10 beds?".

MUST be invoked before any work involving: the `kind: android` schema kind, a `target: android` deploy, the `apk:` layer package format (installing Android apps declaratively), AndroidDeployTarget, an in-pod emulator OR a remote/physical adb-endpoint device, or nested `pod → android` deployment. The first-class Android device + app surface that sits above `ov eval adb`/`appium`.

Use when committing, branching, pushing, merging, tagging, creating PRs, or approving/merging PRs with gh — the feat/-branch, R10-gated, never-force-push landing workflow across the main repo + the plugins submodule + image/<distro> submodules.
