# App build checks

> Detect and validate a project's build and test workflow.

Ask Arka to detect and validate a project’s build/test workflow:

```bash theme={null}
arka app-check .
arka app-check . --run
arka app-check . --run --json
```

Arka detects common Python, Node, Rust, and Go projects. Without `--run` it
only previews checks. With `--run` it stops at the first failure and reports the
command output so the problem can be fixed. Natural language works too:
“build and test this app”. Run checks in an Arka sandbox when validating
generated or untrusted code.
