From e02f4c72c3cac88c47a32c081616d75c1942d65c Mon Sep 17 00:00:00 2001 From: Classic298 <27028174+Classic298@users.noreply.github.com> Date: Tue, 3 Nov 2026 21:02:02 +0100 Subject: [PATCH] feat: plain-language labels for tool calls in chat Tool calls in a chat show up as raw names like "Explored search_web, fetch_url" and "View Result from run_command", which says little about what the assistant actually did. A new Tool Call Summaries setting (Admin Settings > Interface, off by default) lets the task model describe each finished tool call in a few words in the user's interface language, for example "Searched for Tesla Q3 earnings". A collapsed group shows the number of steps followed by the labels on one line, each row shows its own label, and the raw tool name stays in the tooltip. The labels are saved in the chat the first time it is opened with the setting on, so they are generated once and read the same everywhere. If the task model fails, the chat keeps showing the current tool names. --- backend/open_webui/config.py | 22 ++++++ backend/open_webui/constants.py | 1 + backend/open_webui/main.py | 2 + backend/open_webui/routers/tasks.py | 75 +++++++++++++++++++ backend/open_webui/utils/task.py | 34 +++++++++ src/lib/apis/index.ts | 33 ++++++++ .../admin/Settings/Interface.svelte | 31 ++++++++ src/lib/components/chat/Chat.svelte | 42 +++++++++++ .../Markdown/ConsecutiveDetailsGroup.svelte | 58 ++++++++++++-- .../Messages/StructuredOutputRenderer.svelte | 9 +++ .../chat/Messages/structuredOutput.ts | 4 +- .../components/common/ToolCallDisplay.svelte | 38 +++++++++- src/lib/i18n/locales/en-US/translation.json | 5 ++ src/lib/stores/index.ts | 1 + src/lib/utils/toolCallSummary.ts | 70 +++++++++++++++++ 15 files changed, 416 insertions(+), 9 deletions(-) create mode 100644 src/lib/utils/toolCallSummary.ts diff --git a/backend/open_webui/config.py b/backend/open_webui/config.py index 3e98856ec4..8e4e7e4ce0 100644 --- a/backend/open_webui/config.py +++ b/backend/open_webui/config.py @@ -2359,6 +2359,26 @@ JSON format: { "follow_ups": ["Suggested next message 1", "Suggested next messag ENABLE_FOLLOW_UP_GENERATION = os.getenv('ENABLE_FOLLOW_UP_GENERATION', 'True').lower() == 'true' +TOOL_CALL_SUMMARY_GENERATION_PROMPT_TEMPLATE = os.getenv('TOOL_CALL_SUMMARY_GENERATION_PROMPT_TEMPLATE', '') + +DEFAULT_TOOL_CALL_SUMMARY_GENERATION_PROMPT_TEMPLATE = """### Task: +Describe in plain words what each tool call below did, so the user can see at a glance what happened. +### Guidelines: +- Write in past tense, in {{LANGUAGE}} (the language the user set their interface to, so they can read it), from the view of what was accomplished: "Searched for flight options", "Prepared the launch script", "Read the Rust release notes". +- "steps" has exactly one entry per numbered tool call, in order, even when one call does several things.
