Descriptions:
Ray Amjad walks through a batch of new Claude Code updates released in late 2025, covering changes that affect how developers work with Anthropic’s CLI-based coding agent. The most notable addition is instant auto-compacting: conversations that previously took around two minutes to compact now complete immediately, because Claude Code was already building a running session summary in the background. That session memory — stored in `~/.claude/projects/` — tracks completed tasks, discussion points, open questions, and a work log that updates with every message exchanged.
Beyond memory, the update introduces asynchronous agents and bash commands. Developers can now spawn a subagent, push it to the background with Ctrl+B, and continue their main session uninterrupted while the subagent handles research or long-running tasks independently. Once finished, the subagent wakes the main agent and delivers its output via the new agent output tool — a workflow that maps well to situations where a developer wants parallel information gathering without losing their current context.
Other updates include improved session navigation with slash rename and forked-session grouping in `/resume`, and a first-party Claude Rules system that allows developers to modularize their CLAUDE.md files and scope individual rule files to specific directories — similar in concept to Cursor Rules. Amjad, who reports over 1,000 hours of Claude Code use, demonstrates each feature with live examples, making this a practical reference for anyone looking to get more out of Claude Code’s growing feature set.
