Regarding skills: just symlink them. Since opencode and codex share .agents/skills use that for the others also. Just the hooks and mcp integrations are still proprietary. codex needs a config.toml setting, but then you can use eg safe-chains everywhere.

Regarding setup docs: Put it into an .deb and .rpm, put them on a free webserver, and no need to check for updates or setups.
