  The handler for the apply_auto_corrections tool, which uses engine.getAutoCorrections to retrieve and apply corrections.

  case 'apply_auto_corrections': {
    const text = String(args?.['text'] ?? '');
    const toolName = String(args?.['tool_name'] ?? '');
    if (!text || !toolName) {
      return {
        content: [{ type: 'text', text: 'Error: text and tool_name are required' }],
      };
    }
    const corrections = engine.getAutoCorrections(toolName);
    let result = text;
    const applied: string[] = [];
    for (const c of corrections) {
      const re = new RegExp(c.pattern, 'gi');
      if (re.test(result)) {
        result = result.replace(re, c.replacement);
        applied.push(c.name);
      }
    }
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(
            { corrected_text: result, corrections_applied: applied },
            null,
            2,
          ),
        },
      ],
    };
