wundergraph

Use after implementing features, changing configuration, modifying CLI commands, updating router behavior, altering architecture, or making any user-facing changes. Triggers a documentation review to check if docs-website/ needs updating. Use this skill whenever you finish writing code that changes how users interact with the platform — new flags, config options, API changes, new UI features, behavioral changes, deprecations, or new components. Even small changes like adding an environment variable or a new CLI flag need doc coverage.
