HyperFrames
Write HTML. Render video. Built for agents. An open-source framework that turns HTML, CSS, media, and animations into deterministic MP4 videos. Agents write plain HTML compositions and a non-interactive CLI renders them to video; install it into coding agents like Claude Code with npx skills add. Built by HeyGen, licensed Apache-2.0.
PM Skills
A plugin marketplace for Claude Code and Cowork that encodes proven product management frameworks — from Teresa Torres and Marty Cagan — into 68 PM skills and 42 chained workflows across 9 plugins, covering discovery, strategy, execution, market research, data analytics, go-to-market, and growth.
Agent Skills
Production-grade engineering skills for AI coding agents — 24 skills encoding the workflows, quality gates, and best practices senior engineers use when building software. Organized by lifecycle phase (Define, Plan, Build, Verify, Review, Ship), skills activate automatically based on what you're doing: designing an API triggers `api-and-interface-design`, building UI triggers `frontend-ui-engineering`. "Process, not prose" — skills are workflows agents follow, not reference docs they read, and every skill carries evidence requirements like passing tests or runtime data.
Last30Days
An AI agent skill that researches any topic across Reddit, X, YouTube, HN, Polymarket, and the web — then synthesizes a grounded summary. The engine scores results by actual engagement metrics (upvotes, likes, view counts, prediction market odds) rather than editorial authority, resolves entities first (handles, subreddits, GitHub repos, hashtags), runs parallel multi-source queries, merges duplicate stories across platforms, and produces cited briefs. Reddit, HN, Polymarket, and GitHub work immediately with zero configuration.
Herdr
A terminal-native agent multiplexer in a single Rust binary. Herdr combines tmux-style session persistence and pane splits with agent awareness — a sidebar that shows whether each pane's agent is idle, working, blocked, or done — for Claude Code and other CLI agents. The direct Claude Code integration (`herdr integration install claude`) adds full state detection, semantic state forwarding over a local socket API, and agent-session restoration after a server restart.
LLM Wiki
A cross-platform desktop application implementing Andrej Karpathy's llm-wiki.md pattern. Instead of traditional RAG that retrieves and answers from scratch every time, the LLM incrementally builds and maintains a persistent wiki from your sources. A built-in local HTTP API and a companion agent skill let Claude Code query your wiki — "what does my LLM Wiki say about X."
CC Workflow Studio
Design workflows on a canvas in VS Code and export them as Markdown your AI agent already understands — skills, commands, and agents for Claude Code, Cursor, Copilot, and more. An MCP server runs in the background so you can refine workflows in natural language with 'Edit with AI'.
Google Skills
Agent Skills for Google products and technologies — maintained by Google. The repo ships 13 skills: 7 foundational (Gemini API, AlloyDB, BigQuery, Cloud Run, Cloud SQL, Firebase, GKE basics), 3 recipes (Google Cloud onboarding, auth, network observability), and 3 Well-Architected Framework skills (security, reliability, cost optimization), so Claude Code pulls in Google Cloud guidance automatically when those topics come up.
Firecrawl
🔥 The API to search, scrape, and interact with the web for AI. Three integrated capabilities — Search, Scrape, Interact — exposed through one API. Open source under AGPL-3.0 and self-hostable via docker-compose, the engine also powers the firecrawl.dev cloud SaaS run by the same team.
Firecrawl MCP
🔥 Official Firecrawl MCP Server — Adds powerful web scraping and search to Cursor, Claude and any other LLM clients. Exposes 12+ tools spanning single-page scrape, batch processing, site crawl, search, structured extraction, autonomous research agent, and interactive page automation, returning clean LLM-ready markdown.
Perplexity MCP
The official MCP server implementation for the Perplexity API Platform. Provides AI assistants with real-time web search, reasoning, and research capabilities through Sonar models and the Search API.
Codex Plugin for Claude Code
Use Codex from Claude Code to review code or delegate tasks. An OpenAI-published plugin that exposes standard reviews, adversarial reviews, and task delegation as slash commands, plus a Codex subagent and background-job tracking.
Find Skills
A meta-skill that activates when users ask "how do I do X" or "is there a skill that can…", then searches the open agent skills ecosystem and walks the user through installation.
Graphify
Turn any folder of code, SQL schemas, R scripts, shell scripts, docs, papers, images, or videos into a queryable knowledge graph. App code + database schema + infrastructure in one graph.
Caveman
why use many token when few token do trick — a Claude Code skill that cuts output tokens by ~65-75% by talking like caveman.
RTK
A high-performance CLI proxy that compresses dev command output by 60-90% before it reaches the LLM context. Single Rust binary, 100+ supported commands — better reasoning, longer sessions, lower costs.
Slack
Official Slack MCP server for interactive and collaborative workflows. Surface insights, draft messages, and engage teams directly within Slack from Claude Code.
Andrej Karpathy Skills
A single `CLAUDE.md` file to improve Claude Code behavior, derived from Andrej Karpathy's observations on LLM coding pitfalls.
Mixpanel MCP
Mixpanel's hosted Model Context Protocol (MCP) server that gives AI assistants direct access to your Mixpanel data.
Claude-Mem
