What feature would you like to see?
Summary
Codex Desktop currently cannot render local HTML artifacts inline in the conversation, unlike Claude Desktop-style artifact previews.
Current behavior
When Codex generates an HTML file for workflow diagrams, debugging panels, result comparison pages, or tool-chain documentation, the user can only view Markdown/Mermaid in the chat or open the HTML outside Codex manually.
Expected behavior
Codex Desktop should support one of the following:
- Inline preview of generated local HTML artifacts
- A built-in webview/artifact viewer
- A first-class “Open preview” action inside the Codex Desktop UI
Why this matters
This is useful for code-agent workflows where the assistant needs to present:
- Tool-chain architecture diagrams
- Interactive debugging dashboards
- Result comparison pages
- Local report pages generated during analysis
Markdown/Mermaid is helpful, but it is not enough for richer interactive inspection or HTML-based diagnostics.
