Non-interactive and JSON mutations require --yes.

Error message

Non-interactive and JSON mutations require --yes.

What it means

Any non-interactive or --json run that would actually mutate the install must confirm intent with --yes (or be a --dry-run preview). Without --yes and without --dry-run, the installer refuses to proceed to prevent accidental mutations in CI/automation.

Solutions

1. Add --yes to confirm the mutation in non-interactive/JSON mode
2. Add --dry-run instead if you only want to preview the plan
3. Run interactively (with a TTY) so confirmation can be prompted

Example fix

// before
node scripts/install-guided.js --harness claude --claude-scope user --claude-hooks standard
// after
node scripts/install-guided.js --harness claude --claude-scope user --claude-hooks standard --yes

  throw new Error('Add --yes (or --dry-run) for non-interactive/JSON mutations');
}

function hasNonInteractiveConfirmation(argv) {
  return argv.includes('--yes') || argv.includes('-y') || argv.includes('--dry-run');
}

try { validateExecutionMode(options, interactive); }
catch (err) {
  if (/require --yes/.test(err.message)) {
    console.error(`${err.message} (or use --dry-run to preview)`);
    process.exit(2);
  }
  throw err;
}

When it happens

Trigger: Running install-guided.js in CI with all the right selections but forgetting --yes, or using --json without --yes.

Common situations: CI pipelines, Docker builds, or scripted setups where the author omitted --yes expecting a prompt that cannot appear.
