This gives Claude agents their own Git hosting namespace on code.storage. You can create repos, get authenticated clone URLs, and push code using standard Git commands. The key thing to know is that remote URLs expire after an hour by default since auth is embedded directly in the URL, so you'll need to refresh them for long running work. Creating a repo costs 50 cents, getting a writable URL costs a penny, reads are free. It's single owner only, no collaborators, and repos are private unless you explicitly make them public. Useful if you're building agents that need to version and persist code across sessions without managing SSH keys or credential helpers.
