Hook error details are hidden when they could expose secrets in the URL

Some hooks send a request to a web address. Hooks are actions Claude Code runs automatically at set moments. When such a hook fails, Claude Code now hides the error details. It says they may contain the hook's URL and that any secrets in it cannot be reliably removed. The details are shown only when the address starts with http:// or https:// and has no embedded credentials, such as a username or password.

In some cases Claude Code also leaves out timing figures and shortens the output it reports from hooks.
