📄 Description

Add a new per-user interface toggle under Settings > Interface that controls how tool calls are displayed when expanded in the chat UI. The toggle defaults to on, preserving the existing behavior. When turned off:

  • The Output section (raw JSON result) is completely hidden
  • The Input section replaces the JSON code block with a formatted key-value list, converting parameter names from snake_case/camelCase to readable labels (e.g. "search_query" becomes "Search Query")
  • Falls back to raw JSON display if arguments cannot be parsed This is a frontend-only change. Tool call data is still sent to models and stored in chat history unchanged — only the visual rendering is affected.
    Files changed:
  • src/lib/stores/index.ts Added showToolCallOutput to the Settings type definition.
  • src/lib/components/chat/Settings/Interface.svelte Added the toggle variable, onMount initialization from saved settings, and the toggle UI row in the Chat section after "Always Expand Details".
  • src/lib/components/chat/Messages/Markdown/MarkdownTokens.svelte Passes the showToolCallOutput setting as a prop to ToolCallDisplay.
  • src/lib/components/common/ToolCallDisplay.svelte Added showToolCallOutput prop, formatKey helper for converting parameter names to human-readable labels, and tryParseArgs helper for safely parsing tool arguments. Conditionally renders either the original JSON code blocks or the formatted key-value display based on the setting.

1. Would fix: #21440
2. Relates to: https://github.com/open-webui/open-webui/issues/20598
3. Improves: #20878

On by default for backwards compatibility

If toggled on - all tool output no longer gets shown - and tool input gets shown in a key: value format instead of JSON

This should also really help this issue here with hard performance issues with many codeblocks and long response outputs: https://github.com/open-webui/open-webui/discussions/20878
