 This command performs non-interactive repository setup and does not prompt for
 engine selection or secret configuration.
 
 This command:
 - Configures .gitattributes to mark .lock.yml files as generated
 - Creates the dispatcher skill at .github/skills/agentic-workflows/SKILL.md
-- Creates the custom agent at .github/agents/agentic-workflows.md
 - Removes old prompt files from .github/prompts/ if they exist
 - Configures VSCode settings (.vscode/settings.json)
 - Generates/updates .github/workflows/agentics-maintenance.yml if any workflows use the expires field for discussions or issues
