The Brand Sentinel Agent
Architecting the “Librarian” node for agentic brand governance.
The Master Key (API Access)
To bypass the Google authentication “gauntlet,” we are using a Service Account. This file contains the “Robot Credentials” that allow your n8n nodes to communicate with our demo environment instantly.
n8n Setup:
- Open the text file and keep it ready.
- In your n8n Google node, set Authentication to Service Account.
- Copy the Email and Private Key (including the BEGIN/END markers) exactly as they appear in the file.
- Ensure both toggles at the bottom of the credential window remain OFF.
Download Mailchimp Brand Guidelines
We have meticulously “shredded” the Mailchimp Style Guide into high-precision Markdown (.md) silos. These files serve as the “Memory” for your Brand Sentinel RAG library.
The Brand Audit Ledger
A Sentinel without a record is a ghost. Use this Google Sheet to provide a digital paper trail of every audit your agent performs. This is your “Peace of Mind” dashboard for clients.
Setup Required:
- Click the button above to open the master template.
- Go to File > Make a copy and save it to your own Google Account.
- Critical: Move your copy into a new Google Drive folder named “Mailchimp Brand Sentinel”.
- Ensure the “RAG Library” folder (containing your .md files) is also located within this master directory.
