Brand Copywriting Constraints

A lightweight constraint reference for brand copy. The LLM already knows how to write — this skill provides the specific limits, structures, and rules that turn generic copy into brand-precise copy.

TAGLINE RULES

A tagline is the single most compressed expression of a brand. It appears on logos, business cards, social covers, and packaging.

Structure

• Length: 3-5 words maximum. No exceptions.
• No period at the end (taglines are not sentences).
• No brand name in the tagline (it appears alongside, not inside).
