Add explicit guidance to the system prompt that instructs the model to: - Prefer direct answers over tool calls for simple tasks - Only use tools when genuinely needed - Stop making additional calls when enough info is gathered - Categorize tools (generative vs search) with specific usage rules This addresses the issue where models would make excessive tool calls for simple requests like spelling checks or prompt edits.
Replace complex categorization logic with a single clear instruction: "Only use a tool if you cannot answer without it." This follows Anthropic's recommended approach of using simple, direct instructions rather than elaborate rule systems.

Adds a copy button to the left of the edit button for user messages. Both buttons have identical styling.
Match the codebase pattern from CopyToClipBoardBtn that handles older/insecure browsers with a textarea fallback.

Clicking the new Copy button always calls navigator.clipboard.writeText(...) without checking for availability or handling rejections. In non-secure contexts (e.g., HTTP), older browsers, or locked-down environments where navigator.clipboard is undefined or access is denied, this throws a runtime error or unhandled promise rejection on click, which breaks the UX for those users. Consider checking for navigator.clipboard and handling failures (e.g., fallback to document.execCommand or a user-facing error).
