markdown-it's typographer option rewrites characters after parsing, so a literal (c) came out as ©. Agents label steps and options (a), (b), (c) all the time, and an ordinary list rendering as (a), (b), © stops your eye every time. The same option turns ... into an ellipsis, --- into an em dash, and straight quotes into curly ones. Agent output is text people paste back into a shell or a file, so a curly quote in --name="my repo" looks correct on screen and fails when pasted. The markdown file preview had the same problem, showing characters that are not in the file on disk. Every in-app markdown surface now goes through one factory in utils/markdown-parser.ts, which leaves typographer off: agent chat, plan cards, pull request comment bodies and the file preview. The plan card was rendering through its library's built-in parser because it never passed a markdownit prop, and that default has typographer on. Link behaviour is unchanged. The assistant parser keeps its file:// permission and no other surface gains it, and linkify stays on for chat and the default renderer and off for plan cards, matching what each did before.

/**
|
|
* The one place that decides how the app parses markdown.
|
|
*
|
|
* `typographer` stays off. It switches on two markdown-it core rules that
|
|
* rewrite characters the user may copy back into a shell or a file:
|
|
* `replacements` turns `(c)` into ©, `a -- b` into an en dash and `...` into
|
|
* an ellipsis, and `smartquotes` curls straight quotes so `--name="x"` stops
|
|
* being pasteable. Agent output, plans and file previews all have to render
|
|
* the text they were handed.
|
|
*
|
|
* `linkify` is a parameter rather than a shared default because the surfaces
|
|
* disagree today: chat and the default renderer linkify bare URLs, plan cards
|
|
* never have. Unifying that is a product decision on its own.
