# Skill Extractor & Playbook Compiler > Pure Client-Side WebAssembly (WASM) Single Page Application for compiling, consolidating, and exporting AI Agent Skills into single-file playbooks for Claude Code, Cursor, Windsurf, Antigravity, and GitHub Copilot. ## Overview Skill Extractor allows developers, marketers, copywriters, and creators to unpack modular skill packages (from `skills.sh`, GitHub repositories, and NPX commands) into consolidated prompt playbooks without running terminal commands, installing Node.js runtimes, or sending data to third-party servers. ## Core Capabilities - **WASM Linear Memory Engine**: Accelerates fuzzy Levenshtein subdirectory matching, string normalization, token estimation, and FNV-1a hashing in-browser without server overhead. - **100% Client-Side Privacy**: Runs completely in the browser sandbox. No API keys, credentials, or proprietary source code ever leave the user's local machine. - **Multi-Agent Playbook Exporters**: Compiles raw `SKILL.md` repositories and helper scripts into target formats: - Claude Code (`CLAUDE.md`) - Cursor (`.cursorrules` / `.mdc`) - Windsurf (`.windsurfrules`) - Antigravity IDE (`.agents/skills//SKILL.md`) - Standard `skills.sh` (`.skill.md`) - **Deterministic Script Consolidation**: Inlines helper scripts (`scripts/`, `bin/`) and collapsible reference markdown (`references/`, `docs/`) to reduce agent context bloat by up to 78%. - **Multiple Ingestion Methods**: Accepts NPX commands (`npx skills add `), GitHub repository URLs (`owner/repo`), local folders (File System Access API), and drag-and-drop `.zip` files. - **Persistent IndexedDB Gallery**: Full offline storage with live fuzzy search, tag filtering, 1-click clipboard copy, and direct OS file drag export. ## Key URLs & Resources - Web App Compiler: https://skill-extractor.pages.dev/ - Product Landing Page: https://skill-extractor.pages.dev/landing/ - Machine-Readable Pricing: https://skill-extractor.pages.dev/pricing.md - Sitemaps: https://skill-extractor.pages.dev/sitemap.xml - Creator Website: https://birol.tech - GitHub Source Repository: https://github.com/Birol-dev/skills.sh-extractor - License: MIT (Free and Open-Source for personal and commercial use) ## Pricing Summary - Standard Edition: $0 Free (Open-Source, Uncapped Local Executions, Zero Telemetry) - Enterprise & Teams: $0 Free (Self-hostable, Static HTML/WASM Bundle, Zero Backend Infrastructure)
