When to Use

Use this skill when:

• Adding a new subsystem or major package
• Moving responsibilities between local store, cloud, dashboard, or plugins
• Changing sync flow, source-of-truth rules, or persistence boundaries

Core Guardrails

1. Local SQLite is the source of truth; cloud is replication and shared access.
2. Keep plugin/adaptor layers thin; real behavior belongs in Go packages.
3. Prefer explicit boundaries: store, cloudstore, server, dashboard, autosync.
4. New features must fit the existing local-first mental model before they fit the UI.
5. Do not hide cross-system coupling inside helpers or templates.

Decision Rules

• Local-only concern -> internal/store
• Cloud materialization or org-wide control -> internal/cloud/cloudstore
• HTTP contract or enforcement -> internal/cloud/cloudserver
• Browser rendering and UX -> internal/cloud/dashboard
• Background orchestration -> internal/cloud/autosync

---

Validation

• Add regression tests for every boundary change.
• Verify local, remote, and dashboard behavior still tell the same product story.
• If the change touches sync, test both push and pull paths.
