[Vercel Flags](https://vercel.com/docs/flags) segments can now be managed from the [Vercel CLI](https://vercel.com/docs/cli/flags) with the new `vercel flags segments`

command.

A segment is the targeting primitive a flag uses to decide who sees what. Membership composes from three repeatable tokens: `include:`

, `exclude:`

, and `rule:`

. Pass them to `--add`

or `--remove`

for incremental edits. For full replacement, `--data`

takes the entire segment definition as raw JSON.

All segment commands support `--json`

output, making them scriptable from CI, local workflows, and agent-driven pipelines that need to inspect or update flag targeting from the terminal.

Update to the latest version of the Vercel CLI and learn more in the [Vercel Flags CLI documentation](https://vercel.com/docs/cli/flags) to get started.
