Startup timing now records how long hook setup takes for each origin

Claude Code's startup timing now also records the time spent setting up hooks. Hooks are commands you configure to run at certain points while Claude Code works. For each place a hook setup comes from, it keeps the longest time in milliseconds.

This is only recorded when one of these environment variables is set:

• CLAUDE_CODE_REMOTE
• CLAUDE_CODE_EMIT_STARTUP_TIMING

It is also only recorded before the timing report has been used.
