How an AI agent uses Markdown viewer
Read .md files as documents, including the ones your agent just wrote.
Updated · T3rnel Browser 1.3.0
What the agent can do
- GitHub Flavored Markdown: tables, task lists, footnotes, strikethrough, autolinks.
- Mermaid diagrams and LaTeX math rendered inline.
- Sticky auto-generated table of contents with scroll-spy; light, dark and sepia themes.
- Side-by-side diff between two Markdown documents.
- Renders straight from the clipboard, which is the fastest way to read assistant output.
- Sanitises strictly. Markdown is untrusted input, and a viewer with a scripting hole inside an extension is a serious problem — scripts, event-handler attributes and
javascript:URLs are removed, and a payload corpus in the test suite proves it.
