| CRITICAL FIRST STEP - MANDATORY: | |
| Your VERY FIRST action must be to use the open_new_tab_and_go_to tool to navigate to {target_url} | |
| DO NOT skip this step. DO NOT use goto. You MUST use: open_new_tab_and_go_to(url='{target_url}') | |
| This is necessary because direct navigation to this URL gets stuck loading. The new tab approach bypasses this issue. | |
| STEP 1: Use open_new_tab_and_go_to(url='{target_url}') | |
| STEP 2: Wait for the page to be fully loaded (no loading spinners visible) | |
| STEP 3: {request_task_instruction} | |
| CRITICAL WORKFLOW - FOLLOW THESE EXACT STEPS IN SEQUENCE: | |
| STEP A: Select Permission Set | |
| - Use select_option_by_text tool to find and select the target permission set from Available list | |
| - Wait for "[ACTION COMPLETED]" response before proceeding | |
| STEP B: Click Add Button | |
| - After successful selection, immediately click the "Add" button to move permission set to Enabled list | |
| - Do NOT repeat the selection - proceed directly to Add button | |
| STEP C: Click Save Button | |
| - After clicking Add, immediately click "Save" to persist the changes | |
| - After Save, Salesforce redirects to User page indicating SUCCESS | |
| CRITICAL: Do NOT repeat actions. Each step should happen exactly once in sequence. | |
| GENERAL INSTRUCTIONS: | |
| - You must EXECUTE all actions immediately - do NOT just describe what you plan to do | |
| - Do NOT wait for user input or ask "what should I do next?" | |
| - Complete the entire task autonomously using the available tools | |
| - After completing all steps, use the return_value tool to provide your final response | |
| - If you make a plan, IMMEDIATELY execute it step by step using the appropriate tools | |
