Panniantong / Agent-Reach

A CLI scaffolding tool that gives AI agents one-click access to 14+ internet platforms — Twitter, Reddit, YouTube, GitHub, Bilibili, XiaoHongShu, Douyin and more. It auto-installs and configures upstream open-source tools (yt-dlp, twitter-cli, rdt-cli, etc.), and agents call them directly afterward. 100% free, zero API fees. Works with Claude Code, Cursor, OpenClaw, and any CLI-capable agent.

JuliusBrussee / caveman

Caveman is a token optimization engine and local proxy for 30+ AI coding agents (Claude Code, Cursor, Aider, etc.). It cuts token usage and API costs by combining concise 'caveman-style' output prompts with byte-exact input context compression (code, logs, JSON, and text-to-image).

obra / superpowers

An agentic skills framework and development methodology for AI coding agents. Provides 14 composable skills that auto-trigger across the full dev lifecycle—brainstorming, planning, TDD, subagent-driven execution, code review, and branch management. Works with Claude Code, Codex, Gemini CLI, Cursor, OpenCode, GitHub Copilot, and more.

DietrichGebert / ponytail

Ponytail is a lightweight plugin and ruleset for 20+ AI agents (Claude Code, Cursor, Copilot, etc.) that prevents code over-engineering. By guiding AI to prioritize native APIs and standard libraries, it significantly cuts generated code size, token cost, and latency without compromising safety.

pbakaus / impeccable

Impeccable is a design guidance system for AI coding agents (Claude Code, Cursor, Copilot, etc.). Featuring 24 design commands, 61 deterministic detector rules, and live browser iteration, it helps developers eliminate generic AI design tropes and craft polished, high-quality frontend interfaces.

mattpocock / skills

A curated collection of agent skills for real engineering work — not vibe coding. Fixes the 4 biggest AI coding failure modes: misalignment (/grill-me), verbosity (shared language), broken code (/tdd), and architecture rot (/improve-codebase-architecture). Small, composable, model-agnostic, and battle-tested from decades of engineering experience.

NVIDIA / OpenShell

OpenShell is NVIDIA's open-source runtime for running fleets of autonomous AI agents safely and privately. Agents get real capability - reading files, installing packages, calling APIs - while kernel-level sandboxing enforces policy on every file access, syscall, and network connection. Agents never see raw credentials; secrets are injected only into requests bound for approved endpoints. Policy changes are formally verified before approval, with support for Docker, Podman, Kubernetes, and VM runtimes plus Python, TypeScript, Go, and Rust SDKs.

coreyhaines31 / marketingskills

A comprehensive collection of 47 interconnected AI agent skills for marketing tasks — covering CRO, copywriting, SEO (including AI SEO and programmatic SEO), paid ads, growth engineering, retention, sales enablement, and RevOps. Works with Claude Code, Cursor, Windsurf, and any agent supporting the Agent Skills spec. Includes 51+ zero-dependency CLI tools and MCP integrations for platforms like GA4, Stripe, and Mailchimp.

heygen-com / hyperframes

An open-source framework that turns HTML, CSS, and seekable animations into deterministic MP4 videos. Write compositions as plain HTML with data attributes, preview in-browser, and render frame-by-frame via headless Chrome + FFmpeg. Built for AI agents (Claude Code, Cursor, Codex) and automated pipelines, with 50+ reusable catalog blocks, CLI, and AWS Lambda/AWS Cloud Run rendering support.
