agentic-systems-engineering

ai-plugins

A multi-harness marketplace of AI coding-assistant plugins for Claude Code, Codex, and other harnesses that adopt plugin or marketplace concepts.

Plugin catalog

Most plugins ship both a .claude-plugin/ and a .codex-plugin/ manifest and are registered in both marketplace manifests. Codex-only plugins are registered only in .agents/plugins/marketplace.json and intentionally omitted from the Claude Code marketplace. Provider-backed promptfoo evals exercise the relevant marketplace surface for each harness.

When a plugin is added under plugins/, add catalog rows only for the harness marketplaces that list it. Codex-only plugins must not be added to the Claude Code table.

Using the marketplace (Claude Code)

Add this repository as a marketplace, then install a plugin from it:

# From inside Claude Code:
/plugin marketplace add jwilger/ai-plugins      # GitHub owner/repo shorthand
# ...or a local checkout:
/plugin marketplace add ./ai-plugins

/plugin install <plugin-name>@ai-plugins

The marketplace is referenced by its name (ai-plugins) in install commands, regardless of the URL you added it from. List and manage with /plugin list, /plugin marketplace update ai-plugins, and /plugin marketplace remove ai-plugins.
