Setting Up Relayfile

Walks you through mounting cloud providers like Notion, Linear, and GitHub as local files so agents can read and write through normal filesystem operations instead of API calls. The setup flow handles OAuth, backend selection between Nango and Composio, Atlassian site picking for Jira/Confluence, and mount verification. What I like is the detail on writeback debugging: it covers dead letter queues, retry commands, and permission denials, which is exactly where these integrations break in practice. The skill also emphasizes reading provider-specific layout files instead of hardcoding paths, which is the right move given how often these schemas drift. Best for anyone handing filesystem access to an agent that needs to modify external resources.
