Brief types
Every real "brief" convention this site is grounded in, filterable by discipline:
This repo's own brief-adjacent skill: brand-voice
This repository has no dedicated legal-coworker skill and no campaign-brief skill under plugins/cwc-product-management (verified by search this session: cwc-product-management ships exactly one skill, brand-voice). The closest in-repo artifact to a "brief" convention is that skill's own discipline — source a real quoted example before drafting any guideline, present the draft for human confirmation, and record only a sourced, gated write — the same source-before-draft discipline every other row in this table describes for its own discipline.
