Accessibility Agents 4.5.1

This release reworks how Accessibility Agents ships for Codex.

We spent time trying to make the Codex plugin and marketplace path work as the primary distribution model. That research was useful, but the end result was not good enough for a release we would want people to depend on. In testing, local plugin packaging could work on a developer machine and Codex could cache an installed plugin, but discovery and install behavior for third-party plugins was still less predictable than we wanted. Too often the experience still depended on the Codex app UI, extra confirmation steps, or behavior that felt different from the simpler install story people are used to on other platforms.

Because of that, this release moves Codex support to a direct skills-pack model. The repo now ships a full codex-skills/ catalog with all 80 Accessibility Agents skills, and the Codex installer now copies those skills directly into .codex/skills/ for project installs or ~/.codex/skills/ for global installs. That gives us a distribution path that is easier to explain, easier to verify, and much more consistent with how people actually use Codex day to day.

We also removed the old .codex/AGENTS.md baseline from the Codex path. Experimental TOML roles are still available for focused passes, but they are now clearly positioned as optional. The primary Codex story is straightforward: install the skills, restart Codex, and use the agents directly.

What changed in 4.5.1:

• Added a full direct Codex skills pack under codex-skills/ with all 80 Accessibility Agents skills.
• Updated install.sh and install.ps1 so Codex installs copy skills directly into .codex/skills/ or ~/.codex/skills/.
• Removed the old repo-local Codex plugin and marketplace path from the primary distribution flow.
• Removed the obsolete .codex/AGENTS.md baseline from the Codex setup.
• Updated Codex docs to explain the plugin research, what worked, what did not hold up, and why direct skills are now the recommended path.
• Bumped release metadata to 4.5.1 across the changelog and release manifests.

Verification:

• Release version alignment passes across CHANGELOG.md, plugin.yaml, mcp-server/package.json, and gemini-extension.json.
• install.sh passes shell validation.
• The codex-skills/ pack validates with 80 SKILL.md files and required description frontmatter.

If you are already using Accessibility Agents with Codex, the upgrade path is simple: reinstall with the Codex flag and restart Codex so it reloads the installed skills.
