Layer Properties

Packages
RPM (with --setopt=tsflags=noscripts): android-tools, apptainer, apptainer-suid, arch-install-scripts, asciinema, bat, bcc, bpftop, bpftrace, bridge-utils, debootstrap, direnv, dislocker, ecryptfs-utils, fastfetch, fd-find, fdupes, fuse-devel, fuse-dislocker, fuse3-devel, html2text, htop, jdupes, mosh, neovim, podman-compose, podman-machine, podman-remote, podman-tui, qemu-kvm, qemu-user-binfmt, qemu-user-static, rclone, restic, ripgrep, ShellCheck, squashfuse, strace, sysstat, thefuck, yamllint, yq, zoxide
Cross-distro coverage
rpm: (Fedora), pac: (Arch), deb: (Debian + generic Ubuntu), with a ubuntu:24.04: tag-section override. Not every package is available everywhere; per-distro drops are documented inline in layer.yml.
Packages dropped per distro (non-exhaustive):
- Arch:
apptainer-suid,dislocker,ecryptfs-utils,fuse-dislocker,podman-machine,podman-remote,podman-tui— not packaged. - Debian: same drops as Arch, plus
arch-install-scripts(obviously) andapptaineritself (only in bookworm-backports, skipped on trixie). - Ubuntu 24.04: additionally drops
fastfetch— package not in noble main. Handled by aubuntu:24.04:tag section that re-lists the deb packages minus fastfetch.
bat → batcat symlink (Debian/Ubuntu)
Both Debian and Ubuntu rename bat → batcat in their archives to avoid a namespace collision with a legacy bacula utility. The bat package installs only /usr/bin/batcat; nothing lives at /usr/bin/bat. To keep downstream scripts, docs, and declarative tests portable, the layer ships a distro-tolerant symlink task:
tasks:
- cmd: |
if [ -f /usr/bin/batcat ] && [ ! -e /usr/bin/bat ]; then
ln -sf /usr/bin/batcat /usr/bin/bat
fi
user: root
No-op on Fedora/Arch (where /usr/bin/bat already exists from the distro package) — the guard short-circuits. Creates the symlink on Debian/Ubuntu. Idempotent across rebuilds.
fastfetch test — exclude_distros: [ubuntu:24.04]
The fastfetch-binary test is declared with an exclude_distros: filter:
- id: fastfetch-binary
file: /usr/bin/fastfetch
exists: true
exclude_distros:
- ubuntu:24.04
On images whose org.overthinkos.platform.distro OCI label includes ubuntu:24.04, the test runner skips this check with a reason — see /ov-build:eval "exclude_distros: field". This was added because dropping fastfetch from the ubuntu:24.04: tag section is clean, but the baked test probe would otherwise false-fail.
Single-responsibility split: git tooling lives in /ov-coder:gh
In 2026-04 the gh, git, and git-lfs packages were moved out of
dev-tools and into /ov-coder:gh (which is the dedicated GitHub /
git tooling layer). Before that, dev-tools duplicated what gh was
responsible for — two layers installing gh, two layers testing it,
with unclear ownership. If you want the git tooling, compose
/ov-coder:gh alongside /ov-coder:dev-tools.

When to Use This Skill
Use when the user asks about:
- Developer tools in containers
- CLI utilities (bat, ripgrep, fd-find, neovim, gh, etc.)
- Podman tooling inside containers
- The
dev-toolslayer or its packages

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.

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.

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).

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).
