Design vs Docs & Writing · both proven

brainstorming vs changelog-generator

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.

brainstorming

You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation).

Brief: “A small bakery with one location wants more weekday morning customers. They have a loyal weekend crowd, an Instagram account with 2,000 followers, and no budget for paid ads. Work through this with me and produce the result as a single HTML page: the questions you would ask, the ideas you considered, the three you recommend with how to test each one in two weeks, and what you would measure.”

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.
