# `once cache`

Cache management.

## Synopsis

```text
once cache <SUBCOMMAND>
```

## Description

Inspect, read, and write the content-addressed cache that every Once action runs through. `cache stats` reports counts and on-disk size; `cache blob` and `cache action` expose the CAS and action-result tables as primitives for debugging, reproducibility checks, and external tooling. Useful for answering "did this run hit the cache?" without scraping command output.

## Subcommands

- [`once cache gc`](/reference/cli/cache/gc)
- [`once cache blob`](/reference/cli/cache/blob)
