Note to first-time contributors: Please open a discussion post in Discussions to discuss your idea/fix with the community before creating a pull request, and describe your changes before submitting a pull request.
This is to ensure large feature PRs are discussed with the community first, before starting work on it. If the community does not want this feature or it is not relevant for Open WebUI as a project, it can be identified in the discussion before working on the feature and submitting the PR.
Before submitting, make sure you've checked the following:
Target branch: Verify that the pull request targets the dev branch. PRs targeting main will be immediately closed.
Description: Provide a concise description of the changes made in this pull request down below.
Changelog: Ensure a changelog entry following the format of Keep a Changelog is added at the bottom of the PR description.
Documentation: Add docs in Open WebUI Docs Repository. Document user-facing behavior, environment variables, public APIs/interfaces, or deployment steps.
Dependencies: No new dependency was added. The existing i18n extraction workflow was reused and updated to include TypeScript sources.
Testing: Manual validation performed and described below.
[x ] Agentic AI Code: Confirm this Pull Request is not written by any AI Agent or has at least gone through additional human review AND manual testing. If any AI Agent is the co-author of this PR, it may lead to immediate closure of the PR.
Code review: Self-review completed.
Design & Architecture: The change is frontend-only, keeps backend execution untouched, and follows existing chat/source UI conventions.
Git Hygiene: PR is scoped to one logical improvement: native tool activity presentation and its i18n integration.
Title Prefix: Uses feat.
Changelog Entry
Description
This PR improves how native Open WebUI tool calls are displayed in chat by replacing raw internal tool names such as search_web and fetch_url with human-friendly activity labels, grouped summaries, and compact source indicators.
The goal is to make tool execution easier to understand at a glance without changing any backend tool behavior or execution contracts... and have a better design!
This also improves source visibility during tool execution by surfacing compact source indicators directly in the activity row.
When multiple web sources are involved, the UI now shows a stacked favicon capsule with a +N indicator instead of exposing raw technical tool names.
Overall, the tool activity timeline is now much easier to scan during multi-step web retrieval flows.
Added
A frontend presentation layer for native built-in tools.
Better activity labels for native tools such as web search, URL fetching, knowledge access, notes, memories, chats, channels, code execution, images, time tools, and skills.
Compact web source presentation with favicons in tool activity rows.
Direct visual affordance to jump from tool activity to the corresponding sources/citations.
Additional manual translations for the new activity strings in:
fr-FR
fr-CA
de-DE
es-ES
it-IT
Added compact source capsules to tool activity rows, including stacked favicons and a +N count for additional sources.
Added a direct visual bridge from tool activity to citations/sources, making it easier to understand where the assistant browsed content.
Added clearer grouped activity summaries for multi-step native tool usage.
Changed
Consecutive tool activity summaries now group by readable activity family instead of raw function names.
Changed the UX where users would see internal tool names like search_web and fetch_url directly in the chat activity UI.
Changed grouped activity summaries that previously surfaced raw tool function names instead of readable actions.
Changed i18n workflow alignment for TypeScript-based UI string definitions.
The main tool activity row now shows natural-language labels instead of exposing internal tool identifiers.
The i18n parser input now includes src/**/*.{js,ts,svelte} so TypeScript-based UI presentation utilities participate in the normal extraction workflow.
The string set was intentionally reduced to reusable templates to minimize locale churn and keep the PR maintainable.
Deprecated
None.
Removed
Removed raw tool-name-first presentation from the main activity UI for native tools.
Removed unrelated stale locale keys from this feature scope by rerunning the repo’s extraction flow cleanly.
Fixed
N/A
Security
No security changes.
Breaking Changes
BREAKING CHANGE: None.
Additional Information
This is a frontend-only presentation change. Backend tool names and tool execution behavior are unchanged.
Technical tool names remain available in expanded details for transparency/debugging.
The new rendering follows existing Open WebUI visual conventions for sources and citations instead of introducing a separate design language.
The branch is intentionally split into two reviewable commits:
feat(ui): humanize native tool activity display
chore(i18n): register tool activity strings and update locales
The implementation was assisted by Claude Opus 4.6, then manually reviewed and has been tested on my side over the past two weeks. :)
Testing
Manual validation performed:
verified native tool activity rows render human-readable labels instead of raw function names
verified grouped summaries no longer read like search_web, fetch_url
verified favicon/source capsule behavior in the updated tool activity UI
verified npm run i18n:parse succeeds
verified rerunning i18n extraction is stable
verified npm run build succeeds
