Codex supports Claude plugin marketplaces directly, so this repository does not need Codex-specific sidecar metadata.
Install the marketplace with:
codex plugin marketplace add trailofbits/skills
codex plugin list
codex plugin add <plugin-name>@trailofbits
Use this repository's .claude-plugin/marketplace.json for workspace imports.
Skills that include agents/openai.yaml also need interface.display_name and
interface.short_description in that YAML file; plugin metadata does not supply them.
After a metadata fix is published, sync the repository again in your workspace
marketplace to retry failed imports.
To add the marketplace locally (e.g., for testing or development), navigate to the parent directory of this repository:
cd /path/to/parent # e.g., if repo is at ~/projects/skills, be in ~/projects
/plugins marketplace add ./skills
