NestJS architecture patterns for modules, controllers, providers, DTO validation, guards, interceptors, config, and production-grade TypeScript backends.
Configuration patterns using Microsoft.Extensions.Configuration. Covers configuration providers, binding, validation, and best practices for .NET applications. Use when setting up configuration in .NET applications, implementing configuration validation with IValidateOptions, or managing settings across different environments.
Apply when implementing asynchronous payment methods (Boleto, Pix, bank redirects) or working with callback URLs in payment connector code. Covers undefined status response, callbackUrl notification, X-VTEX-signature validation, sync vs async handling, and correct delayToCancel configuration for each async method.
Builds production-ready REST API endpoints with validation, error handling, authentication, and documentation. Follows best practices for security and scalability.
Git security scanner with secret detection, commit validation, and pre-commit hooks. Inspired by ZeroClaw's gitleaks integration.
Review changes for regressions, contract mismatches, quality gaps, and missing validation evidence.
Production-ready React form patterns using React Hook Form (default) and TanStack Form with Zod integration. Use when building forms in React applications. Implements reward-early-punish-late validation timing.
MUST be used whenever reviewing a Dune app for security issues, or before shipping any feature that handles credentials, user input, or external data. Do NOT skip this when the user asks for a security review, security audit, or vulnerability check — run every step in order. Triggers: security, security review, security audit, vulnerability, XSS, injection, credentials, secrets, auth, authentication, authorization, token, sensitive data, input validation, CORS, CSP, dependency audit.
Full browser UAT for web apps — Playwright testing with console/network error capture, accessibility checks, i18n validation, and bug triage. Use when running screen-by-screen UAT or testing specific features in any web or hybrid app (React, Vue, Angular, Ionic, Next.js, etc).
This skill guides the use of Jupyter notebooks for data analysis, exploration, and visualization, particularly with BigQuery. It outlines best practices for notebook execution and validation (supporting both cell-by-cell execution and full notebook generation depending on tool availability), library installation, and structuring notebooks for clarity. It also covers specific rules for data cleaning, plotting, and integrating with BigQuery SQL and machine learning workflows. Relevant when any of the following conditions are true: 1. The user request involves a data analysis, data exploration, data visualization, or data insights task that requires multiple steps, queries, or visualizations to answer. 2. The user explicitly requests a notebook (.ipynb). 3. You are creating, editing, or executing cells in a Jupyter notebook. 4. You need to query BigQuery from within a notebook. DO NOT use the Python BigQuery client library; instead, you MUST use the `%%bqsql` magics explained in this skill.
Build and review Remix 3 applications using the `remix` npm package and subpath imports. Use when working on Remix app structure, routes, controllers, middleware, validation, data access, auth, sessions, file uploads, server setup, UI components, hydration, navigation, or tests.
Portable Zod schema design and validation guidance. Default to `zod/mini` for new work and preserve established classic `zod` surfaces. Use when Codex needs to create, extend, refactor, or review Zod schemas; choose strict or loose object contracts; model nullability, unions, intersections, recursion, or runtime-validated values; or debug surprising Zod behavior and serialization boundaries.
