Snapshot summary built from the project's own GitHub metadata — there's no written TopGit review yet. The page will update automatically when a full review is published.
WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
A Claude Code plugin marketplace from Trail of Bits providing skills to enhance AI-assisted security analysis, testing, and development workflows. Codex can load this marketplace through its Claude marketplace compatibility.
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.
Local Development
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
