data-fair

Pre-PR flight check on the current branch. Re-anchors on the intended change and reviews the diff against it at a macro level — scope, completeness, drift — flags risky or sensitive changes for the reviewer, and drafts a compact PR title (conventional-commit style) and description. Requires a clean working tree. Does not run tests, lint, or type-check, and is not a substitute for line-level code review.

How to add a database migration / upgrade script in a data-fair service that uses @data-fair/lib-node/upgrade-scripts (data-fair, processings, events, catalogs, etc.). Covers the gotcha that trips up most agents: which version goes in the folder name. Use this skill whenever the user asks to add an upgrade script, write a migration, backfill a field on existing documents, reshape a Mongo collection on deploy, or anything described as "needs to run once on production after deploy". Also use it when reading or modifying an existing `upgrade/X.Y.Z/` directory.

How to implement real-time websocket communication in data-fair services. Covers the full stack: server-side setup with @data-fair/lib-express/ws-server, emitting events with @data-fair/lib-node/ws-emitter, subscribing from Vue components with @data-fair/lib-vue/ws, and using @data-fair/lib-node/ws-client for Node.js programmatic WS clients and integration tests. Use this skill whenever the user wants to add websocket support, emit real-time events, subscribe to channels, implement live updates, push notifications, any pub/sub pattern in a data-fair service, or write integration tests that verify websocket behavior — even if they just say "real-time", "live updates", or "test websockets".

How to use the @data-fair/lib session management system in services that consume sessions (not login/account management). Use this skill whenever the task involves reading user identity, checking permissions, protecting routes, accessing account/organization info, or implementing authorization logic in a data-fair service -- both on the Express/Node backend and in Vue frontend components. Also use it when the user mentions session middleware, account roles, admin mode, or organization switching in a data-fair context.
