Design vs Other · both proven

brainstorming vs internal-comms

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.”

internal-comms

A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use. Claude should use this skill whenever asked to write some sort of internal communications (status reports, leadership updates, 3P updates, company newsletters, FAQs, incident reports, project updates, etc.).

Brief: “Write this week's status update for the Checkout Redesign project as a single HTML page for the leadership channel. Facts to use: the new cart page shipped to 10% of traffic on Tuesday; conversion in the test group is up 2.1% so far; the payments team is two days late on the saved-cards work; a legal review of the new terms copy is still open; launch to 100% is planned for the 30th if the saved-cards work lands by Friday. Keep it short enough to read in a minute.”
