+
+prompt: |
+  Audit {{ target_url }} for web accessibility compliance ({{ compliance_level }}).
+
+  **Audit Scope:** {{ audit_scope }}
+
+  **Steps:**
+  1. Fetch the HTML content from {{ target_url }} using the fetch extension
+  2. If fetch fails, try alternative methods or use basic HTML structure analysis
+  3. Analyze the HTML for WCAG accessibility issues
+  4. Create the output directory {{ output_dir }} if it doesn't exist
+  5. Generate all required report files
+
+  **Error Handling:**
+  - If fetch extension fails, attempt to continue with basic analysis
+  - If completely unable to get content, create reports indicating the issue
+  - Always generate output files even if analysis is incomplete
+
+  **Key Areas to Check:**
+  - Images: alt text, decorative images
+  - Structure: headings, semantic HTML
+  - Navigation: links, keyboard access
+  - Forms: labels, error messages
+  - Color: contrast ratios
+
+  **Required Output Files:**
+  - Save the fetched HTML as: {{ output_dir }}/source-html-{{ date }}.html
+  - Create accessibility audit report: {{ output_dir }}/accessibility-audit-{{ date }}.{{ output_format }}
+  - Create summary: {{ output_dir }}/accessibility-summary-{{ date }}.txt
+  - Create JSON metrics: {{ output_dir }}/accessibility-score-{{ date }}.json
+
+  **Analysis Requirements:**
+  - Calculate overall accessibility score (0-100)
+  - Identify critical, major, and minor issues
+  - Provide specific remediation recommendations
+  - Include code examples where helpful
