Arch Studio 1.4.2

Codex becomes a supported host, alongside Claude Code, without changing the as plugin identity or the studio and project record formats.

What’s new

Codex packaging: a Codex plugin manifest and a repository Git marketplace let Codex install Arch Studio as as@skills-for-architects.
Cross-host skills: every bundled skill uses the host's invocation syntax, $skill-name on Codex and /as:skill-name on Claude Code, and resolves bundled scripts and references from the loaded skill instead of Claude-only environment variables.
Workspaces: new studios and projects include Codex AGENTS.md instructions and .agents/skills roots alongside the Claude Code files, and Skill Maker targets the right folder for each host.
Documentation distinguishes the shared skill catalog from Claude Code-only native agents and hooks, and a Codex compatibility test covers manifests, marketplace metadata, skill portability, workspace scaffolds and install commands.

Existing 1.4 workspaces remain valid. New scaffolds add empty Codex instruction and skill roots without moving or duplicating existing Claude Code skills.
The bundled course is available as $learn on Codex and /as:learn on Claude Code.
