Origin Apps

Two skills for building on Cursor Origin, Cursor's code forge. They cover creating an Origin App, calling the API, receiving webhooks, and moving an existing GitHub App over. The plugin is skills only, so it runs in Cursor, Claude Code, Codex, and any agent that reads Agent Skills.

What it includes

origin-api sends the agent to the section of the Origin docs that answers its question and lists the rules to check first: native versus mirrored repositories, event subscriptions, webhook verification, scopes from the spec, opaque tokens and IDs. Use it for any Origin work.

port-github-app-to-origin plans the move of an existing GitHub App. Run it inside the app's repository. It reads what the app uses out of the code, maps that onto the live Origin spec, and writes a porting brief with what carries over and what does not, the webhook fields your handlers read and where each comes from on Origin, the scopes to request, an end-to-end test for your app, feedback for Cursor, and the questions your team has to decide. It plans. It writes no code unless you ask.

Both skills read the live spec at run time and never name an endpoint from memory.

When to use

Ask about the Origin API, or ask to port a GitHub App, and the matching skill loads. In Cursor you can also run /origin-api or /port-github-app-to-origin.

Install in Cursor

Search for Origin Apps in the Cursor Marketplace (cursor.com/marketplace/origin-apps), or open Customize, find the plugin, and install it at user or project scope.

Use outside Cursor

The skills use only portable Agent Skills frontmatter. In Claude Code: /plugin marketplace add cursor/plugins then /plugin install origin-apps@cursor-plugins. Any other agent: copy origin-apps/skills/* into its skills folder (copy both; the porting skill refers to origin-api).

Requirements

  • Network access to https://cursor.com/docs/api/origin/* during the run.
  • For the porting skill, read access to the app's source. Writing the brief needs no Origin credentials. You run the brief's end-to-end test afterwards.

Where the brief goes

The porting skill writes ORIGIN-PORTING-BRIEF.md at the repository root and prints its path. When there is feedback for Cursor, it also writes that section to ORIGIN-FEEDBACK.md, ready to send as is; the rest of the brief is for your team.
