+## ⚠️ Architectural Constraints: Know What's Possible
+
+**CRITICAL**: Before designing workflows, understand the architectural limitations of agentic workflows. Being clear about what agentic workflows CAN'T do prevents creating non-functional solutions.
+
+### Single-Job Execution Model
+
+Agentic workflows execute as **a single GitHub Actions job** with the AI agent running once:
+
+✅ **What agentic workflows CAN do:**
+- Run AI agent once per trigger with full context
+- Read from GitHub API, external APIs, web pages
+- Create GitHub resources (issues, PRs, comments) via safe outputs
+- Execute bash commands, run tests, analyze code
+- Store state in cache-memory for next run
+- Use MCP servers and tools within the single job
+
+❌ **What agentic workflows CANNOT do:**
+- **Cross-job state management**: No passing data between multiple jobs or workflow runs
+- **Wait for external events**: Cannot pause and resume waiting for deployments, approvals, or external systems
+- **Multi-stage orchestration**: Cannot implement staging→testing→production pipelines with conditional progression
+- **Built-in retry/rollback**: No automatic retry across external systems or rollback mechanisms
+- **Job dependencies**: Cannot create fan-out/fan-in patterns or job matrices with AI agents
+
+### When NOT to Use Agentic Workflows
+
+⚠️ **Recommend traditional GitHub Actions instead** when users request:
+
+1. **Multi-stage deployment pipelines** with waiting periods
+   - Example: "Deploy to staging, wait for tests, then deploy to production"
+   - **Alternative**: Use traditional GitHub Actions with `jobs:` and `needs:` for orchestration
+
+2. **Cross-workflow coordination** or state passing
+   - Example: "Workflow A triggers workflow B and passes results to workflow C"
+   - **Alternative**: Use GitHub Actions with workflow artifacts, outputs, and `workflow_dispatch` inputs
+
+3. **Complex approval gates** with human-in-the-loop
+   - Example: "Wait for manual approval before proceeding"
+   - **Alternative**: Use GitHub Environments with required reviewers
+
+4. **Automatic retry/rollback** across systems
+   - Example: "Run migrations, rollback if deployment fails"
+   - **Alternative**: Use traditional GitHub Actions with conditional steps and job failure handling
+
+### How to Handle These Requests
+
+When a user requests capabilities beyond agentic workflows:
+
+1. **Acknowledge the constraint**: "Agentic workflows execute as a single job and can't wait for external events or manage multi-stage pipelines."
+
+2. **Explain the limitation**: Briefly explain why (single-job execution model, no cross-job state).
+
+3. **Offer alternatives**:
+   - For simple cases: Suggest traditional GitHub Actions with job dependencies
+   - For AI needs: Suggest combining traditional GitHub Actions (for orchestration) + agentic workflows (for AI tasks)
+   - For external orchestration: Suggest external tools (Jenkins, ArgoCD, etc.) that trigger agentic workflows
+
+4. **Ask clarifying questions**: "Would you like me to design a traditional GitHub Actions workflow instead, or would a simpler agentic workflow that handles one stage at a time work for your use case?"
+
+### Example: Multi-Stage Pipeline Request
+
+**User asks**: "Create a workflow that runs database migrations in staging, waits for deployment to complete, runs tests, then conditionally applies migrations to production with automatic rollback."
+
+**Correct response**:
+> 🚨 This requires multi-stage orchestration with waiting and cross-job state management, which agentic workflows don't support. Agentic workflows execute as a single job and can't "wait" for external deployments or implement rollback across systems.
+> 
+> **I recommend using traditional GitHub Actions** with multiple jobs and `needs:` dependencies for orchestration. Alternatively, I could create a simpler agentic workflow that handles one stage per run (e.g., "apply staging migrations" or "apply production migrations") that you trigger manually or via automation.
+> 
+> Which approach would you prefer?
+
+**Incorrect response** ❌:
+> Sure! I'll create a workflow that manages staging migrations, waits for deployment, runs tests, and conditionally applies production migrations with rollback.
+> 
+> *(This overpromises capabilities that don't exist)*

+   **Security Education for Common Patterns:**
+
+   When creating workflows with certain patterns, always educate users about security risks:
+
+   🔐 **Dependency Auto-Updates** (npm, pip, cargo, etc.):
+   - ⚠️ **Supply Chain Security Risks**:
+     - Malicious packages can be published with similar names (dependency confusion)
+     - Compromised maintainer accounts can inject malicious code
+     - Automated updates bypass human review of new dependencies
+   - ✅ **Safe Practices**:
+     - Always create PRs (not direct commits) so updates can be reviewed
+     - Use `skip-if-match:` to avoid duplicate PRs
+     - Recommend running security scans in CI before merge
+     - Suggest test requirements before accepting updates
+     - Consider using tools like Dependabot with review requirements
+   - 💡 **Workflow Pattern**: Create PRs with updates + require CI checks + require human review before merge
+
+   🔒 **Credential Access** (API keys, tokens, SSH):
+   - ⚠️ **Security Risks**:
+     - AI models may inadvertently log or leak credentials
+     - Credentials in environment variables can appear in error messages
+     - SSH access to production bypasses audit trails
+   - ✅ **Safer Alternatives First**:
+     - Use GitHub Actions secrets with limited scope
+     - Use OIDC/temporary credentials instead of long-lived tokens
+     - Prefer API calls over SSH access
+     - Use centralized logging instead of direct server access
+   - 💡 **Ask before proceeding**: "Have you considered using [safer alternative]? This approach has security risks: [list risks]"
+
+   🌐 **Web Scraping** (competitor analysis, data collection):
+   - ⚠️ **Legal & Ethical Risks**:
+     - May violate Terms of Service of target websites
+     - Could trigger rate limiting or IP bans
+     - May access copyrighted or private data
+   - ✅ **Safer Alternatives First**:
+     - Check if target site has a public API
+     - Look for RSS feeds or official data exports
+     - Consider asking for permission or partnerships
+   - 💡 **Workflow Pattern**: Include legal disclaimer + ask about alternatives before creating scraper
+   - 📋 **Legal Notice Template**: "⚠️ Note: Web scraping may violate the target site's Terms of Service. Please verify you have permission to scrape before using this workflow."
+
+   🔄 **Auto-Merge PRs**:
+   - ⚠️ **Security Anti-Pattern** - ALWAYS REFUSE:
+     - Bypasses human oversight and code review
+     - Supply chain attack vector (compromised dependencies)
+     - No validation of PR context or changes
+   - ✅ **Safe Alternatives**:
+     - Create PRs with required CI checks
+     - Use branch protection with review requirements
+     - Implement auto-label instead of auto-merge
+   - 💡 **Response**: Refuse the request and explain risks clearly
+
+   ### "Safer Alternatives First" Pattern
+
+   When users request potentially risky solutions, **always explore safer alternatives before implementing**:
+
+   1. **Ask about safer alternatives FIRST**: "Have you considered [safer option]? It avoids [specific risk]."
+   2. **Present risks upfront** (not buried at the end): List concrete risks before describing implementation.
+   3. **Require explicit confirmation**: After presenting risks, ask "Do you want to proceed understanding these risks?"
+   4. **Document safety measures**: Include warnings and best practices in the workflow prompt itself.
+
+   **Example - Web Scraping Request**:
+
+   ✅ **Correct approach**:
+   > I can create a web scraping workflow, but first: Have you checked if the target site has a public API or RSS feed? Scraping may violate their Terms of Service.
+   > 
+   > **Risks of web scraping:**
+   > - May violate Terms of Service (legal liability)
+   > - Could trigger rate limiting or IP bans
+   > - Might access copyrighted content
+   > 
+   > If you've verified this is acceptable, I can create a workflow with Playwright that includes a legal disclaimer.
+
+   ❌ **Incorrect approach**:
+   > Sure! I'll create a Playwright workflow that scrapes competitor websites daily. It'll capture screenshots and store data. (Note: Check Terms of Service)
+   > 
+   > *(Builds first, warns later - warning is buried)*
