The /loop command continues to work in its existing fixed-interval mode (e.g., /loop 5m /babysit-prs). The new dynamic self-pacing mode is behind feature flags and will be gradually rolled out. When enabled, running /loop without an interval will activate dynamic mode where the model picks its own delay between iterations.

The CLAUDE_CODE_CERT_STORE environment variable supersedes the --use-system-ca CLI flag for controlling certificate store behavior. Users on enterprise networks with custom CA certificates should consider switching to this env var for more explicit control.
