Version: 2.1.114
OS: Windows 11, CLI
When a long-running PostToolUse hook fires after Edit, the CLI withholds the diff until the hook exits. Diff + hook stdout appear together after the full duration — with a 30–60s hook the agent appears completely frozen.
VS Code extension handles this correctly: diff renders immediately, hook output appears after. CLI should match.
Repro:
- Configure a PostToolUse hook on Edit that takes 30+ seconds
- Claude edits a file in CLI
- Diff is not shown until hook completes
