Codex Harness: an index of the agent-extension layer
An open directory of Codex plugins and skills, with installation paths, featured projects, and explanations of how the underlying agent harness works.
Why it surfaced
Codex Harness indexes 898 plugins and thousands of skills by parsing plugin manifests, READMEs, and SKILL.md files rather than relying on hand-entered listings. It offers a useful map of the emerging agent-tool ecosystem, from Zoom integrations and life-science research to multi-agent orchestration.
