Build Effective Internal Tooling with Claude Code

Coding agents like Claude Code significantly reduce the time and cost of building internal tooling, making it feasible to automate more tasks. Building effective internal tools involves identifying repetitive or bottleneck processes and then creating solutions that are generalizable, accessible, and well-documented for the entire team. To make tools more robust, one should prompt the LLM to consider various problem variations during development. Examples of such tools include bots for summarizing daily emails and calendars or for assisting in GitHub pull request reviews to improve efficiency.
