In Codex CLI 0.122 the marketplace subcommand moved from
`codex marketplace` to `codex plugin marketplace`. Update README and
docs/codex-setup.md so install snippets work on current Codex (verified
on 0.128.0). Keep one historical reference in the v0.122 callout.
Register the repo as a Codex plugin so `codex marketplace add addyosmani/agent-skills`
installs it in a single step. The plugin reads the existing `skills/` directory via
a symlink — no files are copied, and `skills/<name>/SKILL.md` remains the single
source of truth shared with Claude Code.
- codex/.codex-plugin/plugin.json — Codex manifest, skills: "./skills/"
- codex/skills → ../skills — symlink so the plugin dir stays self-contained
while git tracks a single canonical skills/ at the repo root
- .agents/plugins/marketplace.json — local marketplace entry, plugin at ./codex
- docs/codex-setup.md — install and usage guide
Verified end-to-end with codex-cli 0.121.0: skills appear in the plugin's
Skills list after install.
