Polyglot CI

Skill

polyglot-ci in agent-rules (skills/polyglot-ci/).

Patterns

Release target patterns (common, desktop, lab, …) · skill release-targets · patterns.sdl.

Why

Polyglot distribution · Build pipeline.

House default for new workflows is pattern desktop (GUI) or common (no Mac): Windows + Linux × x64/arm64, plus macOS arm64 when shipping a Mac UI.

Hosted runners we use

OS Arch Runner

windows-11-arm (GitHub-hosted ARM; skip the job if the org has not enabled it)

macOS

macos-14 or macos-15

Do not. Intel GitHub-hosted Macs are not a supported path.

Linux

FreeBSD / OpenBSD / NetBSD

x64 / arm64

No GitHub-hosted images. Use Cirrus CI, a VM, or cross-compile and a smoke test on that kernel.

Copy skills/polyglot-ci/workflow.yml into .github/workflows/release.yml. After the matrix, a pack job runs binary-tailor pack and attaches one GitHub Release asset.

Cosmopolitan optional job

If the project can build with cosmocc, add a job that emits app.com in addition to native slices. Do not replace native GUI/GPU builds with cosmocc unless the app is actually Cosmopolitan-shaped (static, no host .dll).
