Packages
steam(RPM, from RPM Fusion nonfree)gamescope(RPM, Fedora main repos)
XWayland is provided by the base sway candy.
Usage
# charly.yml — requires nvidia base (RPM Fusion nonfree via fedora-nonfree)
sway-browser-vnc-steam:
base: nvidia
candy:
- sway-desktop-vnc
- steam
XWayland
Steam is an X11 application — it requires XWayland. The base sway config has xwayland disable for headless optimization. This candy installs a sway drop-in config at ~/.config/sway/config.d/xwayland.conf that enables XWayland.
Gamescope
Gamescope is a nested Wayland compositor for games. Use it in Steam launch options:
gamescope -W 1920 -H 1080 -r 60 -- %command%
Features: resolution spoofing, FSR/NIS upscaling, FPS limiting, HDR support.
First Login
Steam Guard requires interactive login. Connect via VNC desktop, launch Steam, and log in manually. Auth tokens persist in the steam-data volume for subsequent container restarts.

VerifiedTrustedCommunity
Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

overthinkos/cue
tools
VerifiedTrustedCommunity
The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.
SKILL.mdUpdated Jun 16, 2026
overthinkos/egress
tools
VerifiedTrustedCommunity
CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).

tools
VerifiedTrustedCommunity
Kubernetes cluster-probe declarative check verb — the `kube:` check verb (nodes, pods, ingress, storage class, addon health, apply/delete, and arbitrary resource GETs) served out-of-process by the candy/plugin-kube plugin (vendored client-go; no external kubectl required).
