Additionally, learning how to build and use skills at scale, as outlined in an internal playbook by the Claude Code team, can also be an underrated skill. Having a minimal SKILL.md file is also recommended, and including non-technical information can be helpful. Overall, these skills can help improve the effectiveness and usability of Claude code.
