`amp` groups its commands into a small set of surfaces. Discover them from the terminal:

```bash
amp help                  # all product surfaces
amp help flags            # commands within a surface
amp flags list --help     # flags and examples for one command
amp version
amp auth status
```

## Command families

- [`auth`](https://amplitude.com/docs/developers/cli/commands/auth): authenticate, manage profiles, and inspect credentials.
- [`context`](https://amplitude.com/docs/developers/cli/commands/context): resolve the active credential and org/project context.
- [`projects`](https://amplitude.com/docs/developers/cli/commands/projects): list the projects your credential can access.
- [`events`](https://amplitude.com/docs/developers/cli/commands/events): manage taxonomy, listing, creating, updating, and deleting events.
- [`event-properties`](https://amplitude.com/docs/developers/cli/commands/event-properties): manage the properties associated with an event.
- [`user-properties`](https://amplitude.com/docs/developers/cli/commands/user-properties): manage a project's user properties.
- [`flags`](https://amplitude.com/docs/developers/cli/commands/flags): manage feature flags, listing, creating, reading, updating, and archiving them.
- [`charts`](https://amplitude.com/docs/developers/cli/commands/charts): list, inspect, and query saved charts.

## Human tables vs. piped JSON

`amp` output adapts to who's reading it. In an interactive terminal, list and context commands print human-friendly tables and summaries. Pipe the output to a file or another command, or pass `--json`, and `amp` prints raw, compact API JSON instead, so scripts and agents don't spend effort parsing decoration.

[Configuration](https://amplitude.com/docs/developers/cli/configuration) documents `--json` and the other flags that apply across every command family, such as `--dry-run` and `--yes`.
