- Client page → Brand kit: hashtag sets, approved phrases/CTAs, words to avoid, voice notes
- New post: one-click insert of hashtag sets and phrases, live checks while typing
- Checks: agency named in a client post (refused when saving; the agency's own account is exempt),
avoid list, generic AI-sounding phrases, too many hashtags or emoji, platform length limits
- Brand warnings also appear on drafts; MCP tools brand_kit and caption_check for the AI
