packages/react-hook-form/src/useAssistantForm.tsx (1)

91-107: for (const name of _names.mount) iterates all mounted field names and checks DOM for each, which can be O(n) DOM lookups on large forms, causing measurable UI thread blocking for large forms.

🤖 AI Agent Prompt (Copy & Paste Ready):

Optimize DOM lookup in packages/react-hook-form/src/useAssistantForm.tsx lines 91-107. The current code iterates all mounted field names and performs a DOM lookup for each, which can cause UI thread blocking on large forms. Refactor to first collect all HTMLElement references, then iterate and perform the DOM lookup, reducing repeated property access and improving performance for large forms.

31-45: getPendingToolCalls iterates all messages and all tool calls on every send, which can be O(n*m) for large threads, causing noticeable delays as message history grows.

🤖 AI Agent Prompt (Copy & Paste Ready):

Optimize `getPendingToolCalls` in packages/react-langgraph/src/useLangGraphRuntime.ts (lines 31-45). The current implementation iterates all messages and all tool calls on every send, which is O(n*m) and causes delays as message history grows. Refactor it to memoize results by message array reference and iterate messages in reverse, skipping already-resolved tool calls, to avoid unnecessary recomputation and improve performance for large threads.

packages/react/src/model-context/makeAssistantVisible.tsx (1)

32-32,54-54: setTimeout(resolve, 2000) in both click and edit tools introduces a fixed 2s delay per operation, causing significant UI latency and resource waste for frequent or batch actions.

📊 Impact Scores:

• Production Impact: 3/5
• Fix Specificity: 5/5
• Urgency Impact: 3/5
• Total Score: 11/15

🤖 AI Agent Prompt (Copy & Paste Ready):

In packages/react/src/model-context/makeAssistantVisible.tsx, lines 32 and 54, the code introduces a fixed 2-second delay with `await new Promise((resolve) => setTimeout(resolve, 2000));` in both the `click` and `edit` tool execute functions. This causes significant UI latency and resource waste, especially for frequent or batch operations. Reduce the delay to a minimal value (e.g., 100ms) or make it configurable, ensuring the UI remains responsive.
