Docs & Writing vs Design · both proven

changelog-generator vs web-artifacts-builder

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

changelog-generator

Automatically creates user-facing changelogs from git commits by analyzing commit history, categorizing changes, and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.

web-artifacts-builder

Brief: “Build a single-page trip planner for a four-day weekend in Lisbon as one self-contained HTML file: a day-by-day itinerary with editable stops, a running budget that totals by category, a packing checklist with progress, and a simple map panel drawn with inline SVG that highlights the selected day's stops. State should live in the page and update everywhere when anything changes.”
