The microagents directory location depends on the git provider and actual repository name:

• If git provider is not GitLab and actual repository name is ".openhands": scans "microagents" folder
• If git provider is GitLab and actual repository name is "openhands-config": scans "microagents" folder
• Otherwise: scans ".openhands/microagents" folder
