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.

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.

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.

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.

Building polished PowerPoint decks by hand is slow and hard to repeat. This skill guides Claude, Codex, and Claude Code through PPTX creation, editing, and automation with python-pptx.

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.

Inconsistent project documentation makes installation, use, and contribution difficult. This skill supplies structured templates, formatting guidance, and local tools for maintainable Markdown.

Internal updates often become unclear, too long, or hard to act on. This skill helps Claude, Codex, and Claude Code draft structured reports, announcements, newsletters, and change communications.

Complex Git maintenance can make history changes and conflict resolution difficult. This skill provides structured guidance, recovery steps, and an optional local helper for common advanced workflows.

Custom browser charts often require many D3 decisions before any data appears. This skill supplies chart guidance, templates, helpers, and examples for Claude, Codex, and Claude Code.

Inconsistent API contracts create integration errors and costly migrations. This skill guides REST, GraphQL, OpenAPI, authentication, versioning, validation, and documentation decisions.
