How do I give Claude my client's brand rules for every project?
Write the client's brand rules into 1 client context file. Create 1 Claude Project per client and add that file to its knowledge. Then every chat in that Project starts with the rules. Keep the same file as the source for ChatGPT and Gemini so the rules do not drift.
Step 1: write the rules down. Voice, words to use, words to never use, claims you cannot make, approved proof, and who signs off. If a rule only lives in a reviewer's head, the AI cannot follow it.
Step 2: 1 Claude Project per client. Add the client context file to the Project knowledge. Add a short instruction: follow the client rules file on every draft, and flag anything it does not cover.
Step 3: 1 source, many tools. Your team also uses ChatGPT and Gemini. Keep 1 master file and copy it into each tool from there. Never edit the copy.
Step 4: close the loop. When a reviewer fixes a draft, the fix becomes a new line in the file. That is how the rewrites shrink.
Why it matters. When AGL mapped 1 internal team, 80% of activity involved sharing information and context.
