Open-source AI marketing skills from Eric Siu (Single Grain, Leveling Up podcast). A complete Claude Code–compatible library covering growth experiments, sales pipeline, content ops, outbound, SEO, and finance automation. Eric used it to turn his own campaigns and customer data into a working go-to-market system — then gave it away free.
Anthropic's official open source repository of 11 production plugins built and inspired by their own internal work. Plugins cover Sales, Customer Support, Product, Data, Legal, Operations, and Productivity — turning Claude Cowork into a teammate that learns your people, projects, and terminology instead of acting like a chatbot.
A complete AI agency at your fingertips. From frontend wizards to Reddit community ninjas, from whimsy injectors to reality checkers — each agent is a specialized expert with personality, processes, and proven deliverables. Born from a Reddit thread and months of iteration, The Agency is a growing collection of meticulously crafted AI agent personalities. Each one is deeply specialized (not generic prompt templates), personality-driven with unique voice and communication style, deliverable-focused with real code and measurable outcomes, and production-ready with battle-tested workflows. Think of it as assembling your dream team — except they're AI specialists who never sleep, never complain, and always deliver.
A clean-room Python/Rust reimplementation of Claude Code harness patterns. Claw Code exploded into the record books as one of the fastest repos in GitHub history to surpass 50,000 stars — hitting the milestone in roughly 2 hours after publication. An open-source laboratory for researchers who want to learn exactly how modern coding agents actually work under the hood.
The #1 agentic skills framework for Claude Code, built by Jesse Vincent (obra). Superpowers enforces senior engineering discipline — Socratic brainstorming, red/green/refactor TDD, YAGNI, DRY, and a four-phase debugging methodology — so agents stop hallucinating and start shipping. It's not uncommon to let Claude work autonomously for hours without deviating from the plan.
An AI-powered task management system by Eyal Toledano that drops into Cursor, Claude Code, Windsurf, Roo, Lovable, VS Code, Zed and 6+ more editors. Breaks high-level product requirements down into a full PRD-to-tickets pipeline — main model, research model, and fallback model — so your agents always know what to build next.
The leading multi-agent orchestration platform for Claude — deploy 16+ specialized agent roles in coordinated swarms with fault-tolerant consensus, self-learning behavior, and enterprise-grade security. WASM kernels written in Rust power the policy engine, embeddings, and proof system. Recently renamed from claude-flow to ruflo.

1,000+ toolkit integrations, tool search, context management, authentication, and a sandboxed workbench for building AI agents that turn intent into action. Composio handles OAuth end-to-end — scoped to exactly what your agent needs — so you don't have to wire up rate limits, scopes, and sync logic yourself. Native connectors for Salesforce, HubSpot, Jira, GitHub, Slack, Notion and more.
A powerful desktop GUI for Claude Code built with Tauri 2, React 18, and Rust — from getAsterisk, a Y Combinator–backed startup. Visual project browser, session timeline with checkpoints and branching, custom AI agents, MCP server management, and usage tracking. Bridges the gap between the power of the CLI and the productivity of a real app.
The official Coder-built Neovim plugin for Claude Code. Pure Lua, zero dependencies, and implements the same WebSocket-based MCP protocol as the VS Code extension — so launching Claude inside Neovim gives agents full read/write access to your editor, buffers, and open files. Terminal purists rejoice.
The open-source alternative to Claude Cowork, built for teams and powered by OpenCode. Runs local-first on your machine in one click — then explicitly opts into remote sharing when you need it. Composable as a desktop app, WhatsApp/Slack/Telegram connector, or full server. Extensible with skill plugins, permissioned, and fully auditable.
Packs your entire repository into a single AI-friendly file with one command — optimized for Claude, ChatGPT, Gemini, DeepSeek, Grok, and every other major LLM. Ships with token counting, XML/Markdown/JSON output, git log context, Claude Agent Skills generation, and optional MCP server mode. One of the most useful glue tools in the modern AI dev stack.
A beautiful real-time terminal dashboard for tracking Claude Code token usage, burn rate, and cost — with ML-based predictions that warn you before you hit your session limits. Built by Maciek-roboblog. Essential for anyone running Claude Code heavily enough to care about billing surprises.
A revolutionary collection of DESIGN.md files that capture the design systems of the world's best websites — Airbnb, Stripe, Linear, Vercel, Figma, Notion and dozens more. Drop one into your project and let Claude Code, Cursor, or any coding agent build matching UI in your target brand's exact voice. This is how you teach AI taste.

Building a high-converting app onboarding flow is hard. This Claude Skill does it in 5 minutes. Point it at your codebase and it generates the full questionnaire strategy used by Cal AI ($1M/mo) and Mob ($100K/mo): pain point questions, custom plan generation, app demo flows, and the exact psychology that converts free users to paid. No guessing at the right questions. No hours of UX research. Just the proven framework on autopilot.
Paste a job URL, get back a structured A-F evaluation, an ATS-optimized PDF tailored to that exact role, salary research, interview prep, and a tracker entry. All in one shot. No spreadsheets. No copy-pasting. No spray-and-pray. 14 skill modes including evaluate, scan, PDF generation, batch apply, deep research, negotiation scripts, and LinkedIn outreach. Comes pre-loaded with a portal scanner for 45+ companies (Anthropic, OpenAI, ElevenLabs, Mistral, Cohere, Stripe, Retool, Vercel, Decagon and more) plus 19 search queries across Ashby, Greenhouse, Lever, Wellfound, and Workable.
ATS-optimized PDF generation via Playwright with Space Grotesk + DM Sans. Go terminal dashboard built with Bubble Tea to browse your pipeline. Batch mode evaluates 10+ offers in parallel using Claude sub-agents. An Interview Story Bank accumulates STAR+Reflection stories across evaluations until you have 5-10 master answers for any behavioral question. Auto-fill for application forms. The system literally refuses to recommend applying to anything scoring below 4.0/5. The whole point is to find the few offers worth your time out of hundreds, not to flood recruiters with garbage. It evaluates fit by reasoning about your CV vs the JD, not keyword matching. And because it is all built on Claude Code skills, you can ask Claude to rewrite the system itself.
