How to give multiple AI assistants the same brand guidelines

Establish which brand every assistant should use

Rainbrand maintains shared brand context that agents can retrieve and update. To start:

1. Create an account and follow the MCP quickstart. MCP, the Model Context Protocol, connects AI applications to tools and data.
2. Give the connected agent the brand's website or guide and relevant files. Wait until the brand is ready.
3. Connect the other assistants using their current guide: ChatGPT, Claude, Codex, Claude Code or Cursor. Availability depends on the tool and account.

In each connected assistant:

1. Ask it to show the connected Rainbrand account.
2. List the brands it can access and select the intended ready brand.
3. Record that Brand ID, the identifier for the brand, in your setup notes.

Rainbrand adds a brand to the personal account by default. Name the intended team when adding a shared brand, then select that same brand in every assistant.

You can keep a simple inventory:

Give each assistant a rule for retrieving guidance

A Rainbrand Brief contains selected brand guidance in Markdown and files such as logos, fonts and reference images. Save an instruction to request it where the assistant reads instructions for this work, such as project settings or the repository's instruction file. Replace the bracketed name below.

For [brand] work, use the selected Rainbrand brand. Before drafting or making an output, request a Brief describing the task, audience, channel and any exact copy. Wait for it to complete, then use its guidance and relevant files. Follow the current Brief over older saved brand notes and tell me about any conflict. Pass the guidance and files to any tool making the output. If the brand is unclear or retrieval fails, report that before continuing.

Check that the assistant follows the instruction, then remove the old brand summary so it cannot conflict with retrieved guidance.

Ask for the context each output needs

Request a Brief for the work you are about to make. For an email:

Request a Brief for [brand] for the email described in the attached task. Use its audience, required headline and call to action. Check product claims against the linked current sources. Show me the guidance and selected files before drafting.

For a page, specify its audience and sections; for an image, include dimensions and exact copy. Inspect the returned product names, permitted claims, voice and identity rules before making the work.

Pass the original task, guidance and files to the creation tools. Use the actual logo rather than a description to redraw. A renderer needs font files; a model judging lettering may also need specimen images. Rainbrand supplies the context; those tools make the output.

For Son of a Tailor, Codex requested separate Briefs for a cotton-weight guide and a care insert. The clothing brand's guide explained a buying choice; the insert gave an owner practical care wording. Both used the SON icon and supplied typography, with different instructions for the two tasks.

Keep files together when a tool needs a snapshot

Some tools need downloaded files rather than a live connection. A Brand Skill contains the brand's identity, guidance and asset references as they were when that version was saved. Its exported folder includes the assets themselves.

Keep the entry file, reference documents and linked assets together so relative links work. For each installed copy, record:

• Which brand version it contains.
• Where it is installed.
• How you will replace it after a change.

Replace the folder after a brand change. Remove it if that workflow switches to direct retrieval.

Check a change across the connected workflows

When a brand update is needed:

1. Prepare an edit. Inspect or refine it before the authorised caller applies it.
2. Request a fresh Brief in each affected workflow and check the changed rule.
3. Make and inspect the next output. Record each assistant's result separately.

If the guidance is old, check that the assistant selected the right brand, requested a fresh Brief and replaced its saved copy. If the guidance is current but the output uses an old logo, check the files passed to the creation tool.

Updating the brand does not change completed Briefs, downloaded folders or another assistant's saved settings. The guide to updating AI tools covers replacing those remaining copies.

Use the same reference inside your own product

An embedded assistant's application identifies the customer's brand, retrieves context and passes it to every creation step. Keep the Brand ID and returned version with each output. The embedded-product guide covers the integration; runtime retrieval covers caching and failures.

For your team, start with two workflows: connect them to the same brand, remove old guidance and inspect what each task receives. Record any retained exports in the inventory.
