Explorar skills

Master TypeScript generics for reusable, type-safe abstractions. Use when the user works with generic constraints, conditional types, mapped types, the infer keyword, utility types, recursive types, or needs help building type-safe libraries, APIs, or data structures.

Prevent OWASP Top 10 vulnerabilities in web applications. Activate whenever the user writes API endpoints, form handlers, database queries, authentication logic, file uploads, HTML rendering, or any code that handles user input or external data. Also activate when the user asks about security, hardening, or vulnerability prevention.

Guide for Docker multi-stage builds with builder patterns, distroless and alpine base images, cache mounts, and build args. Use when the user needs to optimize Docker image size, separate build from runtime dependencies, or improve build performance. Trigger when the user mentions multi-stage, distroless, slim images, or Docker build optimization.

Guide git branching strategies, branch naming, and merge/rebase decisions. Use when the user creates branches, asks about Git Flow vs trunk-based development, discusses merge vs rebase, or is setting up a new repository's branching model.

Guide for Anthropic Python/TypeScript SDK usage including messages API, streaming, prompt caching, batches, token counting, and error handling. Use when the user is building with the Anthropic API, setting up Claude SDK, calling messages endpoints, implementing streaming, or troubleshooting API errors.

Guide for creating MCP (Model Context Protocol) servers in TypeScript and Python, including scaffolding, transports, lifecycle hooks, and testing. Use when the user wants to build an MCP server, add tools/resources/prompts to an MCP server, configure stdio or SSE transport, or test MCP server functionality.

Validate data with Pydantic v2: BaseModel, Field validators, model validators, computed fields, discriminated unions, and custom types. Use when the user defines API schemas, validates input data, works with Pydantic models, or asks about data validation in Python. Trigger when you see dict-based data handling that should use Pydantic models.

Use when building UI in React with the reablocks component library (Button, Dialog, Drawer, Select, Calendar, CommandPalette, Tabs, Tree, Tooltip, etc.). Covers ThemeProvider setup, extendTheme, custom variants, mergeThemeClasses, useComponentTheme/useTheme hooks, and the 50+ component index.

React component file conventions covering structure ordering, one-component-per-file, and splitting bloated components. Use when writing or reviewing React components.

Avoid unnecessary useRef in React. Prefer HTML standard features, declarative libraries, state, or custom hooks. Use when writing or reviewing React components.

Propose and write new tests for source files changed in the current session. Detects which functions are already covered and only proposes tests for gaps. Use when the user runs /qf-cover, asks to "add test coverage", asks to "write tests", reacts to the Qualflare hook suggestion, or explicitly invokes this skill. Pass --all to cover an entire file/directory regardless of what changed.

Avoid contradictory state types for async data fetching. Use Suspense or discriminated unions instead. Use when writing or reviewing async data fetching code in React/TypeScript.
