Prepare complete, source-backed HeyClaude content submissions for agents, MCP servers, tools, skills, rules, commands, hooks, guides, collections, and statuslines.

Create portable Agent Skills, generate platform adapters, validate package metadata, and prepare PR-first HeyClaude submissions.

Configure MCP servers in the Claude Desktop app by editing claude_desktop_config.json. Grounded walkthrough covering config file locations, the mcpServers JSON structure, the filesystem server, and how to verify and troubleshoot the connection.

Build JavaScript and TypeScript apps with Bun, an all-in-one toolchain that replaces Node.js, npm, a bundler, and a test runner with one fast binary that executes TypeScript directly.

Configure and optimize Cursor and Windsurf AI code editors for maximum productivity. Set up agent mode, composer features, keybindings, and AI-powered refactoring workflows. Customize with .cursorrules and .windsurfrules for project-specific guidance.

Build high-performance async REST APIs with FastAPI, Python's fastest-growing web framework. Automatic OpenAPI/Swagger documentation, type-safe validation with Pydantic, native async/await support, and dependency injection for clean architecture.

Build full-stack web apps with Svelte and SvelteKit. Minimal runtime overhead, reactive components, and server-side rendering. The most admired frontend framework of 2025. Svelte compiles components to vanilla JavaScript at build time, resulting in zero runtime overhead and exceptional performance.

Optimize frontend build performance with Vite's lightning-fast HMR, code splitting, and tree-shaking. Modern build tooling that has replaced Webpack as the developer favorite.

Run AI inference and serverless functions on Cloudflare Workers AI: call hosted models like Llama, Whisper, and Stable Diffusion through the Workers AI binding, deploy with wrangler, and use D1/R2/KV storage plus the free daily Neuron allocation.

Build intelligent CI/CD pipelines with GitHub Actions, AI-assisted workflow generation, automated testing, and deployment orchestration.

Write and maintain reliable end-to-end tests with Playwright — Microsoft's browser automation library that auto-waits for actionable elements and runs the same suite against Chromium, Firefox, and WebKit.

Analyze and optimize PostgreSQL queries for OLTP and OLAP workloads with AI-assisted performance tuning, indexing strategies, and execution plan analysis.

Build full-stack apps on Supabase via @supabase/supabase-js: a hosted Postgres database with row-level security, realtime subscriptions over websockets, Auth, storage, Edge Functions for serverless logic, and pgvector for embeddings.

Build end-to-end type-safe APIs with tRPC and TypeScript, eliminating code generation and runtime bloat for full-stack applications. tRPC provides end-to-end type safety without code generation, schema stitching, or serialization layers - delivering a lighter, more intuitive developer experience than REST or GraphQL.

Generate React UI with v0 (Vercel): produce shadcn/ui and Tailwind CSS components and full Next.js pages from prompts, then refine and add them to your app with the shadcn CLI.

Compile Rust, C++, or Go to WebAssembly and run it in the browser, Node.js, and serverless runtimes: wasm-bindgen JS interop, WASI for system access, the Component Model, and SIMD.

Master collaborative AI-assisted development with Windsurf IDE's Cascade AI, multi-file context awareness, and Flow patterns for team workflows.

TypeScript-first validation skill using Zod — define schemas once, get runtime checks and inferred types for APIs, forms, and data pipelines.

Transcribe audio files (MP3, WAV, M4A, etc.) using OpenAI Whisper AI and ffmpeg to produce structured, timestamped transcripts with automatic summarization and action item extraction. Supports multilingual transcription, speaker diarization, and meeting minutes generation.

Turn CSV, JSON, or Excel data into publication-ready charts with Python: load it with pandas and render bar, line, scatter, and statistical plots in matplotlib (with seaborn styling), then export high-DPI PNG or SVG.

Clean, filter, join, pivot, and export CSV/XLSX data reliably with reproducible steps. Transform messy spreadsheets into production-ready datasets with pandas. Handle encoding issues, data type conversion, missing values, duplicates, and complex merges.

Fill templated DOCX with data to produce reports, invoices, and formatted documents. Generate professional Word documents programmatically with python-docx or use Jinja2 templates with docxtpl for dynamic content insertion. Support tables, images, headers, footers, and custom styling.

Pull text out of images, scans, and PDFs with the Tesseract OCR engine and OpenCV preprocessing. Run OCR in 100+ languages, read per-word confidence and page orientation (OSD), binarize and deskew for accuracy, and reconstruct tables into CSV or JSON.

Compile JSON Schema (draft-07, 2019-09, 2020-12) into fast validators with Ajv, report every failure by its instancePath, and use Ajv options to coerce types, apply defaults, and remove unknown properties so incoming JSON is both validated and normalized.

Parse web, application, and system logs into structured incidents and timelines with anomaly detection.

Explore and script against REST APIs with comprehensive authentication support (API keys, OAuth 2.0, JWT Bearer tokens, Basic Auth), pagination utilities (cursor-based, offset-based, page-based), retry logic with exponential backoff and jitter, error handling for HTTP status codes, rate limiting with Retry-After hea...

A Claude skill that fetches web pages, strips boilerplate with Mozilla Readability, respects robots.txt, removes duplicate content, and turns the result into structured summaries.
