This guide helps teams embed the Markdown to HTML skill into a controlled documentation process. Start by deciding whether the workflow handles one file, a directory, or a static-site build. Then determine whether marked, pandoc, gomarkdown, Jekyll, or Hugo fits the existing language, pipeline, and target output.

Define input and target

Before conversion, specify the expected Markdown flavor, allowed HTML elements, character encoding, and treatment of relative links. In batch workflows, make sure the output directory is not also used as the input directory. Keep test fixtures that cover headings, tables, links, code blocks, special characters, and deliberately problematic HTML fragments.

Run conversion traceably

Ask the assistant to explain the tool choice and document the relevant configuration options. Check that filenames, paths, and output structure follow the project standard. With Jekyll or Hugo, front matter, theme selection, plugin versions, and build configuration are part of the review. A completed conversion process does not by itself prove that the result is semantically or visually correct.

Secure the output

Treat external Markdown as untrusted data. Sanitize HTML after conversion with a project-appropriate sanitizer and then review links, embedded content, and script possibilities. Restrict external file access for tools that support such access. Tokens, passwords, and private keys must not be placed in Markdown or generated HTML files.

Review and publish

Compare the output with the test fixtures and open a representative page in an isolated preview. Check heading hierarchy, tables, code blocks, mobile presentation, and internal links. Publish or move the output into a production build only after human review. Document the parser, versions, sanitization approach, and known boundaries so later changes remain traceable.

Frequently asked questions

Which tool should I choose?

The choice depends on language, document type, Markdown flavor, and target output. The skill compares marked, pandoc, gomarkdown, Jekyll, and Hugo, but project fixtures still need testing.

Does conversion sanitize dangerous HTML?

Not reliably by default. According to the provider, untrusted input should be reviewed and sanitized with a suitable sanitizer after conversion.
