What
The hookify PostToolUse hook does not handle the SSL certificate issue that occurs when running under Claude Code's Bun-based runtime. Users on macOS without any proxy or corporate SSL see "Self-signed certificate detected" because Bun does not load system certificates. This was reported in issue #24470.
Fix
Added a small utility function that sets the
SSL_CERT_FILEenvironment variable to the macOS system certificate bundle (viacertifior a known path) so that any subprocess or Python network operation uses the correct CA certificates. The function runs at import time and only on macOS, and respects an already-setSSL_CERT_FILEto avoid overriding user configuration.Closes #24470
