Sound like the same brand, whoever writes
Keep a brand-wide guide and per-channel additions in one place, and save a version with every edit. The composer and AI agents read the same guide.
What gets easier
Every writer sounds different
Keep the brand guide and channel guides in one place.
No one knows when the guide changed
Every edit gets a version number, and earlier versions stay.
Reviewing only after the draft is done
Drafts are checked for each channel while you write. Spear warns you but doesn’t block you.
