What problem does it solve? Shipping the Fedi web app to production at app.fedi.xyz is error-prone: deploys only run from web/X.Y.Z tags (never branches), releases must be cut from the previous release tag rather than master, and the package version must match the tag. This Skill walks you through the exact release procedure so a production deploy or feature-flag flip goes out correctly. ## Core Features & Use Cases - Tag-Lineage Release Cutting: Branch off the previous web/X.Y.Z tag, cherry-pick only intended commits, bump ui/web/package.json with yarn, and verify the diff before tagging. - Production Deployment: Dispatch the vercel-prod.yml workflow against the tag and diagnose common failures like branch-ref rejection or version/tag mismatch. - Feature-Flag Flips: Ship production remote flag changes by updating prodRemoteFeatures and crates/runtime/src/features.rs together, then verify live via /api/features. - Use Case: You merged a PR enabling a feature flag and need it live for native apps. Follow the steps to cut web/26.6.2 from web/26.6.1, deploy it, and confirm the flag is true at https://app.fedi.xyz/api/features. ## Quick Start Ask the assistant to cut and deploy the next Fedi web production release containing your merged commits, then verify the live feature flags endpoint.
