Cohere Data Handling

Overview

Handle sensitive data when calling Cohere APIs. Cohere processes text server-side for Chat, Embed, Rerank, and Classify — any PII in your input reaches their servers. This skill covers pre-call redaction, post-call scrubbing, and compliance patterns.

Prerequisites

• Understanding of GDPR/CCPA requirements
• cohere-ai SDK installed
• Database for audit logging

Data Flow Awareness

Your App → [PII Redaction] → Cohere API → [Response Scrubbing] → Your App → User

Key point: Everything you send to cohere.chat(), cohere.embed(), etc.
is processed on Cohere's servers. Redact BEFORE the API call.

Instructions

Step 1: PII Detection

interface PIIFinding {
  type: string;
  match: string;
  start: number;
  end: number;
}

const PII_PATTERNS: Array<{ type: string; regex: RegExp }> = [
  { type: 'email', regex: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g },
  { type: 'phone', regex: /\b(\+\d{1,3}[-.]?)?\d{3}[-.]?\d{3}[-.]?\d{4}\b/g },
  { type: 'ssn', regex: /\b\d{3}-\d{2}-\d{4}\b/g },
  { type: 'credit_card', regex: /\b\d{4}[- ]?\d{4}[- ]?\d{4}[- ]?\d{4}\b/g },
  { type: 'ip_address', regex: /\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/g },
];

 (): [] {
   : [] = [];
   ( { , regex }  ) {
     ( match  text.( (regex))) {
      findings.({
        ,
        : match[],
        : match.!,
        : match.! + match[].,
      });
    }
  }
   findings;
}
