## Check your code

These are the changes. To see which of them reach your code, [scan a public repository](https://since.dev/scan.md), or have your coding agent call `check_code` with your manifest or lockfile over [MCP](https://since.dev/docs.md#mcp). [The API](https://since.dev/docs.md#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### See how out of date your code is.

[Scan a repository](https://since.dev/scan.md). Any public GitHub repository. No sign-in.

### Tell your agent what changed since it was trained.
