fedora-builder
Builder image with package managers and compilation tools. Default builder for pixi, npm, and cargo multi-stage builds (declared via builds: [pixi, npm, cargo]).
Image Properties
| Property | Value | |----------|-------| | Base | fedora | | Layers | rpmfusion, pixi, nodejs, build-toolchain | | Platforms | linux/amd64 | | Registry | ghcr.io/overthinkos |
Full Layer Stack
fedora(quay.io/fedora/fedora:43)rpmfusion— RPM Fusion free + nonfree repo configuration. Applied first so subsequent layers candnf installpackages from RPM Fusion (e.g.x264-devel,ffmpeg-devel,libva-devel)pixi— pixi package manager + env pathsnodejs— Node.js + npmbuild-toolchain— gcc, cmake, autoconf, ninja, git, pkg-config, plus the smithay/cargo build deps (rust,cargo,clang-devel,nasm,wayland-devel,libva-devel,x264-devel,ffmpeg-devel,pixman-devel, …) needed for builder-stage compilation of Wayland compositors like pixelflux. See/ov-coder:build-toolchainfor the full grouped list.
Why rpmfusion is first
The build-toolchain layer's dnf install references packages that live in RPM Fusion free
(libva-devel, x264-devel, ffmpeg-devel). These are required to build pixelflux from
source (its libva-sys, x264-sys, and ffmpeg-sys-next cargo crates link against the
system libs). Without rpmfusion applied first, those dnf install calls would fail.
See /ov-selkies:selkies (Patched pixelflux build pipeline) for the consumer story.
Role in Build System
This image is referenced in defaults.builders as the builder for pixi, npm, and cargo multi-stage builds. It declares builds: [pixi, npm, cargo] to advertise its capabilities. The generator uses it as the FROM stage in multi-stage builds, providing build tools without bloating final images.
Quick Start
ov image build fedora-builder
ov shell fedora-builder
Key Layers
/ov-foundation:pixi— Python package management foundation/ov-coder:nodejs— Node.js runtime and npm/ov-coder:build-toolchain— C/C++ compilation tools
Related Images
/ov-foundation:fedora— parent base
Verification
After ov image build:
ov image list— image appears in listov shell fedora-builder— interactive shell works
When to Use This Skill
MUST be invoked when the task involves the fedora-builder image, multi-stage builds, or build cache configuration. Invoke this skill BEFORE reading source code or launching Explore agents.

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?".

overthinkos/workspace-mount
tools
VerifiedTrustedCommunity
Mounts a virtiofs share tagged `workspace` at /workspace inside a VM guest via a systemd .mount unit. Use when a kind:vm entity shares a host directory into the guest and you need it auto-mounted (and re-mounted at every boot).

overthinkos/android
development
VerifiedTrustedCommunity
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`.

overthinkos/git-workflow
tools
VerifiedTrustedCommunity
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. Covers sync-to-upstream, branch/worktree pruning, the fork+PR path for contributors without write access, and cross-repo @github landing order.
