+## 6. Customer Interaction Guidelines (For AI Agents)
+
+When interacting with users across **any channel** (GitHub issues, web chat, agent sessions), AI agents should follow these guidelines:
+
+> **IMPORTANT**: Always assume users are **3rd party external customers**, not internal developers. Responses must be clear, accessible, and avoid internal Microsoft terminology or processes.
+
+### Key Principles
+
+1. **Be novice-friendly** - Avoid technical jargon; explain concepts in plain language
+2. **Make information digestible** - Use numbered steps, bullet points, and short paragraphs
+3. **Answer completely** - Address every part of multi-part questions
+4. **Show respect** - Treat every question as valid, no matter how basic
+
+### Communication Resources
+- **Common Issues Guide:** [`issue-responses/common-issues-guide.md`](issue-responses/common-issues-guide.md) - Comprehensive troubleshooting reference
+- **Communication Guidelines:** [`issue-responses/customer-communication-guidelines.md`](issue-responses/customer-communication-guidelines.md) - Response templates for all channels
+- **Automated Workflow:** [`workflows/copilot-issue-response.yml`](workflows/copilot-issue-response.yml) - Automatic issue triage and response
+
+### Quick Issue Diagnosis
+
+**Configuration Issues (Most Common):**
+1. Redirect URI encoding mismatch (auth_config.json vs AndroidManifest.xml)
+2. Missing `BrowserTabActivity` in AndroidManifest.xml
+3. Incorrect client_id or signature hash
+
+**Runtime Issues:**
+1. PCA not initialized before use
+2. UI updates not on main thread
+3. Wrong account mode API used
+
+**Build Issues:**
+1. Missing AndroidX properties in gradle.properties
+2. MSAL version conflicts
+3. ProGuard/R8 stripping required classes
+
+### Response Protocol
+
+1. **Always acknowledge** the issue with empathy
+2. **Check the common issues guide** before investigating
+3. **Request missing information** using the standard template
+4. **Reference documentation** and code snippets
+5. **Never share** sensitive information or make timeline promises
+
+### Diagnostic Information to Request
+
+When an issue is unclear, ask for:
+- MSAL version
+- Android version and device model
+- Account mode (Single/Multiple)
+- Complete error message or stack trace
+- Relevant configuration files (redacted)
+
+Enable verbose logging for detailed diagnostics:
+```java
+Logger.getInstance().setLogLevel(Logger.LogLevel.VERBOSE);
+Logger.getInstance().setEnableLogcatLog(true);
+```

+A comprehensive reference guide for diagnosing and resolving common MSAL Android issues. Includes:
+- Configuration issues (redirect URI encoding, client ID, manifest setup)
+- Authentication errors (AADSTS codes, user cancellation)
+- Token acquisition issues (deprecated APIs, scope formats)
+- Broker integration issues
+- Build and dependency issues
+- Runtime crashes
+- Single vs Multiple account mode issues
+- Silent token refresh issues
+
+### [customer-communication-guidelines.md](customer-communication-guidelines.md)
+Guidelines for professional and effective communication when responding to GitHub issues. Includes:
+- Communication principles and response time expectations
+- Response templates for various issue types
+- Issue triage guidelines
+- Escalation procedures
+- Quality checklist
+
+## Automated Issue Response
+
+The repository includes a GitHub Actions workflow ([../workflows/copilot-issue-response.yml](../workflows/copilot-issue-response.yml)) that:
+- Automatically triages new issues
+- Applies appropriate labels (bug, feature-request, question, priority)
+- Posts initial acknowledgment and guidance
+- Detects common error patterns and provides targeted help
+
+## Usage
+
+### For AI Agents
+1. Reference `common-issues-guide.md` when analyzing issue descriptions
+2. Use templates from `customer-communication-guidelines.md` for responses
+3. Follow the diagnostic checklist to request necessary information
+4. Link to relevant documentation and code snippets
+
+### For Team Members
+1. Review and update these guides as new common issues emerge
+2. Ensure templates remain current with API changes
+3. Monitor automated responses for accuracy
+4. Escalate security issues through proper channels
