Cursor adds side chats and transcript search

Cursor's July 10 changelog focuses on workflow ergonomics rather than a single flashy model feature. Side chats let users branch off into research or clarification threads without interrupting the main agent run, while transcript search makes long agent histories easier to mine. The release also upgrades repo and project pickers and adds deeper cloud-agent hooks. Together, those changes make Cursor feel more like a programmable operating environment for agents instead of just a chat window inside an editor.

Key Features or Updates

The headline addition is side chats that inherit context from the main conversation but stay durable and separate. Cursor also added transcript search, in-chat find, better project and repo pickers, and new hooks such as beforeSubmitPrompt, afterAgentResponse, and subagent lifecycle controls.

Impact on Developers

This is a meaningful quality-of-life upgrade for anyone running agents on real codebases where context sprawl becomes the bottleneck. Searchable transcripts and programmable hooks make it easier to audit agent behavior, recover prior work, and build tighter automation around long sessions.

How to use it

Use side chats for tangents like dependency research, architecture alternatives, or API checks while your main coding thread stays clean. If you run cloud agents for team workflows, wire the new hooks into observability or policy layers so you can monitor prompts, responses, and subagent behavior.
