What
When piping input to Claude Code from a slow command, a warning is now shown after 3 seconds if no stdin data has been received, helping users diagnose piping issues.
Details
- Warns: "Warning: no stdin data received in 3s, proceeding without it. If piping from a slow command, redirect stdin explicitly: < /dev/null to skip, or wait longer."
- Uses a configurable timeout to detect stalled stdin
Evidence
Stdin timeout detection (search for "no stdin data received in 3s")
