💡 Auto-generated documentation-based answer:

This appears to be a bug report about Mermaid diagram rendering in PR descriptions when double quotes are used in the flowchart syntax. The issue is that when double quotes are included in Mermaid syntax (like A["process.env.GRAPHQL_PLAYGROUND === \"true\"?"]), the chart fails to render properly.

This is likely related to how Qodo Merge generates and formats Mermaid diagrams in the /describe tool. The /describe tool includes a feature called "Sequence Diagram Support" that generates Mermaid diagrams by default.

Potential solutions:

1. Disable Mermaid diagrams temporarily - You can disable the diagram generation by setting:

   [pr_description]
   enable_pr_diagram = false

2. Report the bug - This appears to be a bug in how Qodo Merge handles escaping of quotes in Mermaid syntax. You should report this issue to the Qodo Merge team.

3. Workaround - If you need diagrams, try avoiding double quotes in node labels or use single quotes where possible.

The Mermaid diagram feature is enabled by default via the pr_description.enable_pr_diagram parameter, so disabling it should resolve the immediate rendering issue while the underlying quote escaping problem is addressed.

Extra:
I really like the mermaid chart that was recently added.

1. this change should help:
   https://github.com/qodo-ai/pr-agent/pull/1944/files#diff-a52546bc2f8a156d8ee786c403e44b1561a6e3f1d98fcfbe8a0120bcee59981bL51-R74

2. in the end, it depends on your LLM quality.
   If you see that error often (and you shouldn't, with a modern LLM.), then you may need to turn the feature off
