Master Firebase backend services including Authentication, Firestore, Realtime Database, Cloud Functions, Storage, and Hosting. Learn security rules, data modeling for read-heavy workloads, and cost optimization to avoid pitfalls like expensive reads and query limitations.

Build mobile and web backends using Firebase managed services including Auth, Firestore, and Cloud Functions. Ideal for serverless APIs, real-time data sync, and rapid prototyping with minimal backend code.

GraphQL enables clients to request precise data structures through a single endpoint with a typed schema. This skill covers schema design, resolvers, DataLoader optimization, federation for microservices, and client integration tools like Apollo. It emphasizes treating the schema as a contract and understanding when to use GraphQL versus REST for complex data relationships.

Detects hardcoded secrets like API keys, tokens, and passwords embedded in source code, configuration files, or Infrastructure as Code (IaC). Used when an agent can access its codebase to identify security vulnerabilities at rest. Focuses on secrets stored in files rather than runtime leaks.

This skill is designed to detect and rewrite text that exhibits common characteristics of AI-generated Chinese writing, such as rigid structures, mechanical connectors, and over-polished phrasing. It helps users 'de-AI' their content by restoring natural human rhythm. Key use cases include reducing AIGC signals in academic papers (for CNKI/VIP checks), and converting the writing tone to specific styles like Zhihu, Xiaohongshu, or literary prose.

Hunting skill for GraphQL vulnerabilities. Provides methodology to discover endpoints, test introspection, map schemas, and exploit authorization flaws across GraphQL and REST APIs.

Generate and edit images using Gemini's Nano Banana Pro model (gemini-3-pro-image-preview). Supports text-to-image, image editing, multi-image composition, and Google Search grounding. Provides Python, JavaScript, and REST API examples.

Aggregates official auctioneer information from all 27 Brazilian Commercial Boards into a SQLite store, exposes a FastAPI REST interface, and enables CSV/JSON exports plus customizable scraping per state.

Implement Kubernetes security contexts, Pod Security Standards, network policies, and RBAC to harden clusters and workloads. Includes YAML examples for restricted pods, default-deny networking, and least-privilege access.

This comprehensive guide details how to configure, integrate, and troubleshoot live email sending using Mailtrap. It covers two primary methods: the Email API (REST) and SMTP. Learn the differences between core email streams—transactional (app-generated notifications), bulk (promotional marketing), and batch requests (high-volume efficiency)—along with recommended integration patterns and specific technical endpoints.

This skill enables security auditing of meme coins and tokens on EVM and Solana blockchains. It identifies critical vulnerabilities like hidden mint functions, honeypot transfer restrictions, fee manipulation, and liquidity pool drains. Users must obtain explicit authorization before scanning targets to ensure ethical use.

Administer, optimize, and secure MongoDB NoSQL databases in development and production. Covers installation, user setup, CRUD operations, indexing, aggregation pipelines, replica sets, and backup/restore.
