1. fern/01-guide/02-languages/ruby.mdx:30

  Stray backtick (`) detected here. It appears immediately after the code block and may be an accidental typo. Consider removing it for clarity.

4. engine/language_client_codegen/src/version_check.rs:104

• Draft comment:
  The Python update instruction includes "or uv add baml-py=={gen_version}". This phrasing is unclear and might be a typo—should it be "or use uv add ..."? Please double-check that "uv" is indeed the intended command.
• Reason this comment was not posted:
  Comment looked like it was already resolved.

5. fern/01-guide/02-languages/python.mdx:70

• Draft comment:
  Typographical error: "commmand" appears to have an extra 'm'. Consider changing it to "command".
• Reason this comment was not posted:
  Comment was not on a location in the diff, so it can't be submitted as a review comment.

6. fern/01-guide/02-languages/typescript.mdx:151

• Draft comment:
  Typographical suggestion: "Typescript" is used in the heading on line 151, but the correct capitalization is "TypeScript".
• Reason this comment was not posted:
  Comment was on unchanged code.

7. fern/01-guide/05-baml-advanced/dynamic-types.mdx:263

• Draft comment:
  Typo: There is a missing space before the parenthesis in "BAML function(in this case it's User)". Consider updating it to "BAML function (in this case it's User)" for clarity.
• Reason this comment was not posted:
  Comment was on unchanged code.

8. fern/03-reference/baml_client/client.mdx:368

• Draft comment:
  The closing tags on lines 368 and 369 seem inconsistent. Is the opening tag <Tabs>? If so, the first closing tag should likely be </Tabs> instead of </Tab>. Please verify and fix as needed.
• Reason this comment was not posted:
  Comment looked like it was already resolved.

9. fern/03-reference/baml_client/client.mdx:384

• Draft comment:
  It looks like the Python code snippet is incomplete. The line from baml_client.async_client import b appears to be truncated—was the intended import missing a module or object name?
• Reason this comment was not posted:
  Comment looked like it was already resolved.

10. fern/03-reference/baml_client/typebuilder.mdx:330

• Draft comment:
  There appears to be a trailing backslash at the end of line 330 (tb.User.add_property("email", tb.string()) \). If this wasn't intentional for line continuation, please remove it.
• Reason this comment was not posted:
  Comment was not on a location in the diff, so it can't be submitted as a review comment.

11. fern/03-reference/baml_client/typebuilder.mdx:368

• Draft comment:
  Typo: 'modyfing' should be corrected to 'modifying' in the header '## Creating/modyfing dynamic types with the add_baml method'.
• Reason this comment was not posted:
  Comment was on unchanged code.
