powersync-ja

Translates a pull request (and any linked content) into documentation updates. Researches existing pages, identifies gaps, drafts changes, and presents a plan before writing. Use when asked to document a feature, update docs for a PR, or write docs from a linked issue, RFC, or spec.

Documentation writing mode for PowerSync docs. Activates collaborative or autonomous writing with full awareness of PowerSync standards. Use when writing new pages, updating existing content, or restructuring documentation.

Guided onboarding and best practices for building applications with PowerSync — Cloud and self-hosted setup, sync configuration, client SDK usage, backend integration (Supabase, custom Postgres, MongoDB, MySQL, MSSQL), and debugging. Use this skill whenever the user mentions PowerSync, offline-first sync, local-first architecture, sync rules, sync streams, uploadData, fetchCredentials, real-time data replication, or wants to add offline-capable sync to a mobile or web app — even if they don't explicitly name PowerSync.
