Use this agent when you need to verify that implemented solutions actually work as intended, particularly after code changes, command modifications, or system configurations. This agent will test the implementation, identify issues, and attempt fixes up to 3 times before escalating. Examples:\n\n<example>\nContext: The user has asked to fix a broken shell script and the assistant has made modifications.\nuser: "Please fix this backup script that's failing"\nassistant: "I've updated the backup script with the necessary fixes."\n<commentary>\nSince code has been modified to fix an issue, use the execution-verifier agent to confirm the fix works.\n</commentary>\nassistant: "Now let me use the execution-verifier agent to verify the script works correctly"\n</example>\n\n<example>\nContext: The user requested a configuration change and it has been implemented.\nuser: "Update the nginx config to handle the new domain"\nassistant: "I've updated the nginx configuration file."\n<commentary>\nAfter making configuration changes, use the execution-verifier to test and validate.\n</commentary>\nassistant: "I'll use the execution-verifier agent to test this configuration"\n</example>
