When asking the Gemini model to provide the raw Markdown code for a full file (such as a README.md) that natively contains its own code blocks (like ```text or ```bash for setup instructions), the system wraps the overall response block in triple backticks as well.
Because it uses the exact same triple-backtick delimiter for both the outer wrapper and the inner file code blocks, the first inner closure sequence prematurely kills the main markdown wrapper block. This fragments the code block in the chat interface and ruins the one-click “Copy Code” function.
Actual Behavior:
The response breaks out of the code block layout as soon as the first internal markdown block ends, leaving the user with multiple broken UI chunks instead of a single, continuous markdown file template.
Expected Behavior:
When a markdown output requires nested code blocks, the outer container should automatically scale up to four backticks (````markdown … ````) or handle escaping sequences intelligently so the output remains intact within a single container.
This issue frequently disrupts development workflows when requesting complete documentation templates, multi-directory file trees, or onboarding files. It requires users to manually copy multiple distinct pieces of text and reconstruct the formatting boundaries themselves.
Suggested Solution / Fix:
The system should automatically default to four backticks (````) for the outer markdown code fence whenever nested triple-backtick blocks are detected in the generated content.
Note: Manually instructing Gemini in the prompt to “wrap the whole file in 4 backticks” actually works perfectly and prevents the layout from breaking. However, the model should handle this scaling dynamically by default without requiring explicit user instructions.
