Claude Code runs /code-review as background subagent

In the latest version of Claude Code, the /code-review feature has been transitioned to run as a background subagent. Instead of loading every referenced file into the primary chat context and cluttering the workspace, the subagent loads all file references within its own isolated environment and returns only the final summary and review results.

// ANALYSIS

Offloading context-heavy operations to isolated background subagents is a vital structural shift for LLM-based developer tools.

* Prevents context window bloating and degradation by isolating raw file reads and large diff dumps inside subagent threads.

* Improves agent efficiency and reduces token consumption during long-running coding sessions.

* Establishes a design pattern where developer tools delegate specialized commands to autonomous background workers rather than executing everything in a single linear turn.
