combine — Claude Code skill: Combine API reference
A skill that searches Combine documentation and answers questions about publishers, subscribers, operators and async data streams.
npx skills add Prisma-Labs-Dev/apple-skills --skill combine -a claude-codeWhat combine does
The skill is user-invocable and runs in a forked context with the Explore agent, so it reads the docs rather than your project files. There is one file behind it: combine-index.md, covering the framework overview, publishers, subscribers and operators.
Answers follow a fixed shape. A short summary comes first, then the paths to the files holding the details. That helps when you need to recall which operator does what without leaving the editor.
It fits Swift work on reactive streams. On a project in another language the reference has nothing to say, so skip it there.
What it helps with
- recall which Combine operator performs a given transform
- tell a publisher apart from a subscriber
- locate the framework overview file instead of grepping the repo
- get a short answer with a file path instead of a guess
Example prompts for the agent
- which Combine operators merge two streams?
- explain the difference between a publisher and a subscriber
- find the async streams section in combine-index.md
