# atmos ci cache delete

Delete a CI cache entry by its exact key. Deleting a key that does not exist is a no-op.

> ⚠️ Experimental

:::info Runs locally
Like [`list`](/cli/commands/ci/cache/list), `delete` administers the cache over the provider's public API and works from your workstation as well as inside CI. It needs a GitHub token (`GITHUB_TOKEN` / `ATMOS_GITHUB_TOKEN`, or `gh auth login`) and a GitHub repository (resolved from `GITHUB_REPOSITORY` or your local `git` remote).
:::

**Configure the CI Cache**

Configure the cache in your `atmos.yaml`.
