Problem: npm install outputs "up to date in Xms" to stdout, which prepends
non-JSON text to the hook output. Claude Code expects pure JSON and cannot
parse the output, causing context injection to fail silently.
Solution: Changed npm install flag from --loglevel=error to --loglevel=silent
to completely suppress stdout output, ensuring clean JSON output for hook.
Impact: SessionStart hook will now properly inject recent context into sessions.
