Best Practices
Stop using authentication helpers immediately to patch critical vulnerabilities.Before: Risk of credential theft and supply chain attacks. After: Secured environment with updated patches. Implement session memory files to retain agent context across windows.
Without this: Agents redo work or make inconsistent decisions. With this: Consistent session state, improved workflow. Adopt Karpathy's CLAUDE.md config to cut token waste by 40%.
Before: Excessive token usage. After: Significant cost savings and faster Claude Code performance.
