X discussion: Shopify CEO Tobi Lütke backs the monorepo as a Shopify engineer calls it a boon for coding agents, while critics still prefer split repos
Shopify distinguished engineer Burke Libbey posted on November 1 that moving to a monorepo has been a boon for agents at Shopify; it needs thoughtful tooling and has downsides that take effort to mitigate, but he would not go back. He was replying to Darren Shepherd, who said a day earlier that he hates the idea that monorepos are great for agents. Shopify CEO Tobi Lütke then quoted Burke and recalled Mikhail Parakhin telling him that every engineer hates the idea of moving to a monorepo, yet once it is there no engineer would want to work somewhere without one. Tobi's post drew about 1,115 likes, 454 bookmarks and 89K views and set off a wide debate. These are practitioner opinions, not an official technical announcement.

Cursor marketplace served a tampered Claude Code 2.1.313 extension with an SSH backdoor, affecting at most 5,000 users
Cursor posted a security notice on X at 07:46 UTC on Oct 30: version 2.1.313 of Anthropic.claude-code in its VS Code extension marketplace was a maliciously modified build, not developed by Anthropic, available from about 2:27am to 1:35pm PT on Oct 29 and affecting at most 5,000 users. The payload collects host details, adds an attacker SSH key, tries to open a reverse SSH tunnel and installs persistence. Cursor pulled the version, shut down and rebuilt the marketplace, rotated keys and had the attacker server taken offline; it asks users to update Claude Code for VS Code to 2.1.314 and follow the check and cleanup steps in its blog post.

Anthropic replaces git with in-house Scion: daily merges grew from ~2,500 to 30,000+, and a 7-person team migrated the monorepo in five months
On Oct 13 Anthropic's engineering blog said merges grew from about 2,500 per day in May 2026 to more than 30,000 in September, making human-scale git infrastructure its biggest bottleneck. A seven-person team built Scion, an always-online version control system, plus the Antique code-review tool, and fully migrated the monorepo off git in five months. Scion's footprint is 200x smaller in CPU and memory than the old git mirrors, CI checkouts went from minutes to seconds, and CI gained 25% CPU capacity. Scion is not being open-sourced; Anthropic wants to work with GitHub, GitLab and the OSS community to bring the ideas to git.
