claude_runner 1.1.0

# CLI Parameter: --verbosity

Control how much diagnostic output the runner itself emits. Does not
affect Claude Code subprocess output.

- **Type:** [`VerbosityLevel`](../type/05_verbosity_level.md)
- **Default:** 3 (normal)
- **Command:** [`run`](../command/01_run.md)
- **Group:** [Runner Control](../param_group/02_runner_control.md)
- **Validation:** must be integer 0–5; out of range → error

```sh
clr --verbosity 0 "Silent run"    # suppress runner output
clr --verbosity 4 "Debug"         # verbose command preview
```

**Note:** Fatal errors bypass the verbosity gate — spawn failures and binary-not-found errors are always emitted to stderr at every level, including 0. `--dry-run` output is similarly unaffected by verbosity level. Level 0 suppresses runner diagnostics only; it does not silence errors that indicate the subprocess could not be launched.
