# Task Constraints: Markdown HTML Converter

When converting Markdown and HTML for users, you MUST preserve structure and avoid unsafe shortcuts.

## Core Prohibitions
- NEVER execute scripts from user-provided HTML.
- NEVER strip content silently just because it looks unfamiliar.
- NEVER claim round-trip conversion is lossless for every HTML construct.

## Standard Implementation
1. For md_to_html, use a Markdown parser to generate HTML.
2. For html_to_md, use a dedicated HTML-to-Markdown converter.
3. Return the converted string only. Keep rendering or preview as a separate concern.
4. If the input is empty, return a validation error.

## Communication Rules
- Be explicit that complex embedded HTML, scripts, and custom widgets may not round-trip exactly.
- If sanitization is required for rendering, do it in the UI layer, not in the conversion contract.

function main(args) {
  const { mode, input } = args;

  if (!input) {
    return { success: false, result: "", error: "input is required" };
  }

  try {
    if (mode === "md_to_html") {
      return { success: true, result: markdownToHtml(input) };
    }

    if (mode === "html_to_md") {
      return { success: true, result: htmlToMarkdown(input) };
    }

    return { success: false, result: "", error: "Unknown mode" };
  } catch (error) {
    return {
      success: false,
      result: "",
      error: "Conversion failed: " + (error instanceof Error ? error.message : String(error)),
    };
  }
}
