If you are building or modifying anything that uses PowerSync, you must follow the playbook in skills/powersync/AGENTS.md — not a condensed summary.
That file includes:
- Agent compliance (non-negotiable): ask Cloud vs self-hosted, ask backend if unspecified, CLI-first, no silent shortcuts.
- Full onboarding sequence, setup paths, SDK references, and debugging.
Do not assume Supabase, assume self-hosted Docker, or skip CLI steps unless the user explicitly opts out.
powersync login is PowerSync Cloud only. Self-hosted does not use it — see skills/powersync/references/powersync-cli.md § “Authentication”.
When editing files under skills/powersync/, preserve and strengthen playbook language so agents cannot reasonably treat references as optional recipes.
