Summary
Markdown file links in assistant responses are rendered as clickable blue links, but clicking them does not open the file in VS Code.
Instead, VS Code webview rewrites the path into a URL like:
https://file+.vscode-resource.vscode-cdn.net/c%3A/Users/hp/.vscode/extensions/openai.chatgpt-26.304.20706-win32-x64/webview/...
That URL is then opened in Chrome and fails to resolve.
Actual Behavior
- External browser (Chrome) opens.
- Browser navigates to a
file+.vscode-resource.vscode-cdn.netURL and fails. - No editor navigation occurs.
Impact
- Breaks normal review workflow for line-level findings.
- Makes assistant file references cumbersome to use.
- Creates confusion because links appear like editor-navigation links but behave like broken web URLs.
Notes
- As a workaround, non-clickable plain references (e.g.,
main.c:33) are usable with manual jump (Ctrl+G). - This looks like a webview link-routing/URI-conversion issue for Windows absolute paths.
What steps can reproduce the bug?
- Open VS Code with the Codex extension enabled.
- In chat, ask for a code review that includes file/line references.
- Click a rendered blue link to a local file line (example in response:
main.c:33). - Observe behavior.
What is the expected behavior?
- Click should navigate inside VS Code to the local file and line (or at minimum open file in editor).
- No external browser launch for local workspace file references.
