Repositories Covered#

ECC#

The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. 264K stars.

claude-code#

Claude Code is an agentic coding tool by Anthropic that lives in your terminal. Understands your codebase, executes routine tasks, explains complex code, and handles git workflows through natural language.

agent-skills#

Production-grade engineering skills for AI coding agents by Addy Osmani. Battle-tested skills covering code review, testing, performance, accessibility, and security.

docling#

Document processing for gen AI. Parses diverse formats including PDFs, DOCX, PPTX, and images into structured data. Used by IBM Research.

paperless-ngx#

Paperless-ngx is a document management system that transforms your physical documents into a searchable online archive so you can keep, well, less paper.

financial-services#

Reference agents, skills, and data connectors for financial-services workflows from Anthropic. Covers investment banking, equity research, and trading desk automation.

x-algorithm#

The core algorithm powering the For You feed on X (Twitter). Open-sourced by xAI. Shows how recommendation systems rank and surface content.

supermemory#

Memory and context engine for AI that is extremely fast, scalable, and can run fully locally. Number one on LongMemEval benchmark for long-term memory.

cua#

Open-source computer-use agent infrastructure. Scale computer-use with cross-OS fleets, open-source drivers, and benchmarks for training and evaluation.

stagehand#

The SDK to extract data and interact with any site on the web. Built for agents, not testing. Works with Claude Code, Codex, and any LLM.

Cap#

Beautiful, shareable screen recordings. Open source Loom alternative built in Rust with Tauri. Fast, lightweight, and built for teams.

security-audit-skill#

A coding-agent skill from Cloudflare that turns your agent into a security auditor. Orchestrates isolated agents through reconnaissance, vulnerability scanning, and verified findings.

browser-harness#

Self-healing browser harness that connects an LLM directly to your real browser through one editable CDP websocket. Enables LLMs to complete any web task.

json-render#

The Generative UI framework from Vercel. Guardrailed so AI can only use components in your catalog. Predictable JSON output matches your schema every time.

OpenStock#

Open-source alternative to expensive market platforms. Track real-time stock prices, set personalized alerts, and explore detailed company insights. Free forever, built openly.

coder#

Self-hosted cloud development environments and AI agents. Define environments in Terraform, run on EC2, Kubernetes, or Docker. Auto-shutdown idle resources.

higgsfield#

Fault-tolerant, highly scalable GPU orchestration and ML framework for training models with billions to trillions of parameters. Open-source distributed training.

agent-native#

A framework by Builder.io for building agentic applications with shared data, application state, and agent chat surfaces. Integrates with existing React apps.
