v1.4.2 — Codex compatibility

[1.4.2] - 2026-08-10

Added

• Added .codex-plugin/plugin.json and a repository Git marketplace at .agents/plugins/marketplace.json, allowing Codex to install Architecture Studio as as@skills-for-architects.
• Added Codex AGENTS.md templates and .agents/skills/ roots to new studio and project workspaces alongside the existing Claude Code files.
• Added a Codex compatibility contract test covering manifests, marketplace metadata, skill portability, workspace scaffolds, and documented installation commands.

Changed

• All bundled skills now translate Architecture Studio invocation syntax by host: $skill-name on Codex and /as:skill-name on Claude Code.
• Bundled scripts and references resolve from the loaded skill path through portable <skill-root> and <plugin-root> placeholders instead of requiring Claude-only environment variables.
• Skill Maker now targets .agents/skills/ on Codex and .claude/skills/ on Claude Code while preserving catalog, studio, project, and global ownership boundaries.
• Installation, data-governance, deployment, workspace, and contribution documentation now distinguishes the shared skill catalog from Claude Code-only native agents and hooks.

Compatibility

• The studio/project record formats and as plugin identity are unchanged. Existing v1.4 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. Its shared exercises preserve the six-module progress format while clearly branching for Codex's AGENTS.md, .agents/skills/, and new-session surfaces versus Claude Code's CLAUDE.md, .claude/skills/, and /clear; Claude-native agents and hooks remain unavailable on Codex.
