+ * GitHub CLI Complex Markdown Body Solution
+ * 
+ * This example demonstrates the solution for issue #40:
+ * How to safely pass complex markdown content with backticks, quotes,
+ * variables, and special characters to GitHub CLI commands.
+ * 
+ * Problem: Using `gh issue create --body "${complexContent}"` fails due to
+ * shell escaping issues with special characters.
+ * 
+ * Solution: Use the githubCli helper functions that automatically handle
+ * complex content using temporary files with the --body-file parameter.

+  const complexIssueBody = `## 🐛 Bug Description
+GitHub CLI commands fail when trying to pass complex markdown content through the --body parameter.
+
+## 📝 Problem Details
+When using \`gh issue create --body\` with markdown containing:
+- Code blocks with triple backticks: \`\`\`javascript
+  const result = await $\`command with \${interpolation}\`;
+  console.log('Output:', result.stdout);
+\`\`\`
+- Inline code with single backticks: \`gh issue create\`
+- Dollar signs with variables: \${HOME}, \${USER}
+- Mixed quotes: "double quotes" and 'single quotes'
+- Command substitution: \`date\` or $(whoami)
+- Shell operators: && || & | > < >> <<
+
+The shell interprets these special characters causing command failure.
+
+## 🔧 Solution Examples
+
+### Method 1: Using githubCli.createIssue()
+\`\`\`javascript
+import { githubCli } from 'command-stream';
+
+await githubCli.createIssue(
+  'owner/repo', 
+  'Issue Title', 
+  complexMarkdownBody,
+  { assignee: 'user', labels: ['bug'] }
+);
+\`\`\`
+
+### Method 2: Using githubCli.withBodyFile()
+\`\`\`javascript
+import { githubCli } from 'command-stream';
+
+await githubCli.withBodyFile(
+  ['issue', 'create'],
+  complexMarkdownBody,
+  { repo: 'owner/repo', title: 'Issue Title' }
+);
+\`\`\`
+
+### Method 3: Manual temporary file approach
+\`\`\`javascript
+import { $ } from 'command-stream';
+import fs from 'fs/promises';
+
+const tempFile = '/tmp/issue-body.md';
+await fs.writeFile(tempFile, complexMarkdownBody);
+await $\`gh issue create --body-file \${tempFile}\`;
+await fs.unlink(tempFile);
+\`\`\`

+- Handles all special characters safely
+- Automatic temporary file management
+- No escaping headaches
+- Works with any markdown complexity
+- Production-ready error handling`;
