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.
“Design a set of launch banners for Brightline Coffee's new cold brew cans, as one HTML page showing each banner at its real size: a 1200x628 social ad, a 1080x1080 square post, a 728x90 leaderboard, and a 1600x500 website hero. Price $3.50 a can, in stores June 1.”

“Draw the message flow of this login protocol as a single HTML page with an SVG sequence diagram, and note any weaknesses.
1. Client sends username to server.
2. Server replies with a random 16-byte nonce and the user's salt.
3. Client computes H = SHA-256(salt || password) and sends HMAC-SHA256(key=H, msg=nonce).
4. Server looks up stored H, computes the same HMAC and compares.
5. On success the server returns a session token valid for 30 days.”
