Brand Voice

Define a brand's voice and write the single file every other copycraft skill reads: .claude/brand-brief.md in the user's project. This is the foundation skill. Run it first; copy-polish, texten-de, lokalisieren-de, du-sie-check, landing-page, seo-copy, and the rest all consult the brand brief so they stay consistent and never re-ask the basics.

Your job here is not to write marketing copy. It is to interview the user, make the hard decisions explicit, and record them in a brief that downstream skills can obey.

When to use

• The user is setting up a brand, a product, or a new copy project.
• The user asks for tone of voice, positioning, target audience, proof points, a terminology glossary, or a banned-words list.
• The user needs to decide du or Sie for German copy (and have it stick).
• Any other skill notices there is no .claude/brand-brief.md and the work needs one.
