📄 Description

Problem

In multi-turn conversations involving tool calls, messages retrieved from the database contain HTML-escaped JSON (e.g., ", &, '). The processDetails function in the frontend inserted this HTML-escaped content directly into messages, causing the LLM to receive malformed, hard-to-parse content.
This degraded model performance in tool-heavy chats, as subsequent turns would contain escaped entities.

Solution

Use the existing unescapeHtml utility function to decode HTML entities in tool call results before inserting them into the message content.

Changes

src/lib/utils/index.ts: Modified the processDetails function to call unescapeHtml on attributes.result before replacement

Testing

Started a new chat and sent a message triggering a tool call (e.g., web search)
Sent a follow-up message
Inspected the request payload in browser DevTools
Verified the assistant's previous message now contains clean JSON without HTML entities

Fixes #20600
