## Halliday Claude Code Plugin

For users developing with [Claude Code](https://claude.com/product/claude-code), Halliday now has an official plugin available to automate tedious tasks of development.

The `/halliday` command with a guided menu of flows:

* **Ask questions and learn** — Answers backed by a bundled reference library of the official documentation pages, SDKs, and live Halliday API lookups.
* **Clone a sample application** — Pick from several example open source repos and walk through setup end-to-end.
* **Check my integration** — Scan your codebase against an integration checklist and flag only the items that could cause issues with the Halliday integration.
* **Look up a payment** — Fetch a payment by ID, show a clear status summary with explanation, and give status-specific next steps.

The Halliday Claude Code plugin is now available in the [Anthropic community marketplace](https://github.com/anthropics/claude-plugins-community). After installing Claude Code on the command line, add the plugin using the Anthropic community marketplace:

```
claude plugin marketplace add anthropics/claude-plugins-community

To work on a personalized fork, the plugin can be utilized in development mode using git and these commands:
