Designing SQLModel models and CRUD code can be slow when relationships and async sessions are involved. This skill guides Claude, Codex, and Claude Code through models, queries, relationships, and database setup.

React component work often needs consistent structure, hooks, tests, stories, and accessibility checks. This skill guides Claude, Codex, and Claude Code toward typed, testable React components.

JWT authentication requires careful token creation, validation, and claim handling. This skill guides FastAPI implementations for access tokens, dependencies, RBAC, and safe configuration.

Next.js App Router work often requires precise file structure and component boundaries. This skill guides page, layout, route, and dashboard implementation with Server Component defaults.

FastAPI projects need consistent structure for routes, schemas, auth, database sessions, and CORS. This skill guides Claude, Codex, and Claude Code to create maintainable backend patterns.

Environment settings often spread across files and deployment targets. This skill provides typed FastAPI patterns for .env templates, validation, and secret handling.

Database schema changes can break applications or lose data when they are handled manually. This skill guides Alembic setup, migration generation, rollback planning, and review for SQLModel and FastAPI projects.

Database setup can fail when URLs, SSL, and pooling are inconsistent. This skill provides FastAPI and SQLAlchemy patterns for Neon PostgreSQL connections, sessions, health checks, and pool settings.

APIs and forms often drift when validation rules are copied between layers. This skill gives Claude, Codex, and Claude Code practical patterns for shared schemas, clear errors, and safer input handling.

Document-heavy apps need relevant answers without exposing every file to every user. This skill shows Context7 ingestion, search, and role-scoped retrieval patterns.

Adding a chat widget to a React app requires careful client loading, configuration, and credential handling. This skill provides focused implementation patterns for ChatKit widgets in Next.js and React.

Authentication work is easy to under-specify and hard to secure. This skill guides Claude, Codex, and Claude Code through forms, sessions, protected routes, and role checks.

API teams need reliable tests across backend endpoints and browser flows. This skill provides pytest, FastAPI TestClient, Playwright, fixtures, and CI patterns.

Designing REST API routes is hard when validation, status codes, pagination, and response models are inconsistent. This skill gives FastAPI patterns for predictable endpoints, Pydantic schemas, errors, filtering, sorting, and OpenAPI documentation.

API clients need consistent auth, caching, validation, and error handling. This skill guides TanStack Query, Axios, JWT interceptors, Zod parsing, and offline behavior.

SwiftUI projects can accumulate state, layout, accessibility, and performance problems. This skill provides focused review guidance and optional Instruments trace analysis to identify practical improvements.

Swift concurrency diagnostics and migration choices can be difficult to interpret. This skill provides targeted guidance for isolation, Sendable, tasks, testing, and Swift 6 refactoring.

Creating reliable Excel workbooks requires careful formula, formatting, and data handling. This skill provides structured workflows for building, editing, and analyzing spreadsheets with Python tools.

Manual browser testing is slow and often misses regressions across forms, devices, and network states. This skill helps Claude, Codex, and Claude Code create practical Playwright tests for real web workflows.

Database work often slows down when queries, indexes, and migrations are hard to reason about. This skill gives Claude, Codex, and Claude Code structured SQL guidance for safer and faster database changes.
