Check your code
These are the changes. To see which of them reach your code, scan a public repository, or have your coding agent call check_code with your manifest or lockfile over MCP. The API reads every change in every version, not only the newest. On Team and up, a fix pull request opens for the changes that reach a connected repository. Nothing merges or deploys.
Put your code on continuous management.
Scan a public repository now, or give your agent one line.
See how out of date your code is.
