React SPA patterns for Frappe-backed applications. Reference for TanStack Query, Axios, Jotai, shadcn/ui, Tailwind, Refine v4, Mantine v5, React Router, Vite config, and Frappe API integration in the Unity Parent App and Walsh Admin Portal.

Production-grade Frappe background jobs and scheduler — queue selection, idempotency, retries, distributed locks, monitoring stuck jobs, debugging worker hangs, chunked long-running jobs. Use when designing or debugging frappe.enqueue / scheduler_events code, troubleshooting stuck jobs, or making jobs robust against retries and worker restarts. Complements server-scripts (which covers basic syntax) with the production reality.

React Native / Expo patterns for Frappe-backed mobile apps. Reference for Axios API calls, React Query v4, Redux Toolkit, React Navigation, expo-location, NetworkContext, transport journey lifecycle, attendance flow, and EAS builds.

Frappe Print Format design — Jinja templates for receipts, certificates, invoices; PDF generation; page handling; multi-currency; wkhtmltopdf rendering. Use when designing or modifying a Print Format, troubleshooting PDF rendering, or formatting documents for print. Follows the team convention of self-contained formats — no `letter_head`/`footer` injection.

How to write robust Frappe tests — FrappeTestCase, factories, mocking frappe.sendmail / external HTTP, permission tests, change_settings, anti-patterns to avoid. Use when writing or reviewing test_*.py files, designing test fixtures, or thinking about test isolation. The /frappe-test command runs tests; this skill teaches how to write them.

Frappe Workflow design — multi-state document lifecycles, role-based transitions, state-scoped field permissions, workflow handlers, and the team's pragmatic deviations (Custom Field for workflow_state, db_set over apply_workflow, custom workflow DocTypes). Use when designing or modifying an approval flow, a state machine on a DocType, or anything involving Workflow / Workflow State / Workflow Transition.
