Learning: LLM prompts stored as Python string literals in the codebase still need to comply with linting rules like removing trailing whitespace and using standard ASCII characters, but line length limits can be more flexible if the formatting is critical for prompt effectiveness.

37-37: LGTM – Comment uses standard ASCII quotes.The change from curly quotes to straight quotes improves consistency and editor compatibility.
Based on learnings, using standard ASCII characters in code comments is preferred for linting compliance.

🛠️ Refactor suggestion | 🟠 Major
Use Tailwind arbitrary value instead of inline style.
The inline style attribute violates the coding guideline that requires using Tailwind CSS utility classes for all styling. Tailwind supports arbitrary values that provide the same constraint without breaking consistency.
As per coding guidelines, "All UI components must be styled using Tailwind CSS utility classes."
🔎 Proposed fix using Tailwind arbitrary value
- <div
- className={cn("w-full", disabled && "pointer-events-none")}
- style={{ maxHeight: "7.5rem" }}
- >
+ <div
+ className={cn(
+ "w-full max-h-[7.5rem]",
+ disabled && "pointer-events-none",
+ )}
+ >📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In
src/frontend/src/components/core/parameterRenderComponent/components/promptComponent/index.tsx
around lines 96 to 99, replace the inline style setting maxHeight: "7.5rem" with
the Tailwind arbitrary utility by adding max-h-[7.5rem] to the className; update
the cn call to include "max-h-[7.5rem]" (and keep the existing "w-full" and
conditional "pointer-events-none") so no inline style attribute remains and
styling follows the Tailwind guideline.
This pull request introduces a minor UI improvement and a small comment clarification in the
PromptAreaComponentcomponent. The main change is the addition of a maximum height to the main container, which will help with layout consistency and prevent overflow issues.UI improvement:
