Turns a product and audience into a creative brief: distinct messaging angles selected from a fixed vault of fourteen, each mapped to a funnel stage and a channel, with placement specs and the reason that angle suits that stage. Use when starting a new ad campaign, when existing creative has fatigued and every variant is saying the same thing, or when a brief is needed before any asset gets designed. Boundary: this decides what the creative says and where it runs. `product-photography` then directs the photography and `onboarding-video` produces video. For the wording of a specific LinkedIn opening use `hook-writer`.
