Every data person knows the drill. Someone drops a new dataset in your Slack. You open it, stare at 40 columns and 50,000 rows, and spend the next two hours doing what you always do — profiling nulls, checking distributions, writing up "here's what the data says" for the third time this month. That two hours? I automated it. With a Claude Skill. It's called DataStory — upload any CSV or Excel file, and it produces a full executive data narrative report in seconds. Zero manual analysis. I open-sourced it at github.com/dinesh0666/data-story. Here's exactly how it works. What is a Claude Skill? If you haven't seen these yet — Claude Skills are installable instruction sets (SKILL.md files) that teach Claude a specific repeatable workflow. When you install a skill and then trigger it (by uploading a file, using certain phrases, etc.), Claude reads the skill definition and executes the workflow step by step. Think of it like a .github/workflows YAML, but for AI-driven tasks instead of CI/CD.
