Open source. Open possibilities.

Curated archive of leaked system prompts from ChatGPT, Claude, Gemini, Grok, Copilot, Cursor, Perplexity and others, captured verbatim and organized by vendor with recent additions and change log.

Ruflo is an agent meta-harness for Claude Code and Codex that enables multi-agent swarms, self-learning memory, RAG integration, federation, and extensive plugin ecosystem to build coordinated AI workflows.

A local-first review surface for writing with AI coding agents, allowing users to annotate and edit documents while routing feedback back to the agent session.

Context Engineering Protocol provides AI coding-agent skills that assemble human-approved, source-attributed context packages — code graphs, requirements, org conventions, and constraints — before generation runs. It detects gaps, conflicts, and staleness across sources, gates output behind explicit human approval, and supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex.

TangleClaw is an AI coding session orchestrator for macOS that wraps Claude Code, Codex, Antigravity, Aider, and OpenClaw sessions in persistent tmux processes. It provides session continuity, structured wrap summaries, searchable history, secure remote access via Caddy, inter-session agent messaging, and a dashboard PWA — all with zero npm dependencies.

An AI job application framework built on Claude Code that evaluates job postings, tailors CVs, writes cover letters, and preps interviews — all running locally on your machine.

Xonsh is a full-featured, cross-platform shell that uses Python 3 as its language, seamlessly integrating shell commands with Python. It runs on Linux, macOS, Windows, BSD, Jupyter, Android, Raspberry Pi, and Nix, with an extension system and AI-friendly features.

CodeAgent Mobile clients provide CLI, VS Code/Cursor/Windsurf, and JetBrains plugins to control AI coding agents (Claude Code, Copilot, etc.) from a phone or dashboard, enabling remote approval and workflow continuity.

Swarm is a local-first control plane for AI-agent development that monitors every Claude Code, Codex, Gemini, Grok, Aider, and opencode session on your machine — tracking live tool calls, token spend, cost, tasks, worktrees, and resources — with rules enforcement, a coordination ledger, and a unified dashboard.

Hosted MCP server providing Claude, Cursor and other AI agents with live website analytics, A/B testing, funnel analysis, heatmaps and paid-ads attribution resolved to Stripe revenue. Includes 12 marketing skill prompts for conversion optimization, copywriting, SEO and more.

Gateship is a local-first delivery runtime for coding agents. It gives a task an isolated Git worktree, runs a local Claude Code or Codex session, verifies acceptance commands, adds an independent read-only review, and ships a squash-merged pull request. State lives in local SQLite, served by a Bun web UI on 127.0.0.1.

Zikra is a self-hosted MCP memory server for AI coding agents and teams. It provides a shared, project-scoped memory layer across multiple agents, with role-based access, hybrid semantic and keyword search, structured memory types, and optional PostgreSQL storage.

DesignMD is a CLI tool that extracts live design systems from any URL — colors, typography, spacing, breakpoints, and interaction states — and outputs a portable DESIGN.md file optimized for AI coding agents.

Agent Reach is an internet access capability layer for AI Agents, automating tool selection, installation, health checks, and routing for platforms like YouTube, Bilibili, Twitter/X, and Reddit. Compatible with Claude Code, Cursor, and others, it supports multi-backend failover and local diagnostics.

A forensic UI cloning tool for Claude Code and Codex that converts live URLs into React and Tailwind implementations by extracting real CSS and motion parameters.

CoalLedger is a docs-health checking suite for AI coding agents — the documentation counterpart to CoalMine's code canaries. Seven canaries flag wrong, incomplete, stale, contradictory, broken, unreadable and (optionally) leaked documentation, with a bundled zero-dependency CommonMark+GFM AST engine, context-judged severity and choice-gated fixes.

ECC is an agent harness operating system that provides a coordinated engineering system and toolbox for AI agents, enabling structured workflows like planning, testing, and reviewing.

17-lesson tutorial teaching harness engineering for AI agents: build the tools, knowledge, permissions, and context management around an LLM agent loop, using Claude Code as the reference design. Runnable Python examples progress from the agent loop to a goal loop.

cc-grass reads Claude Code session logs under ~/.claude/projects (and optionally Codex CLI sessions) and renders a GitHub-style orange contribution-graph SVG you can commit to a profile README. Zero dependencies, Node 18+, incremental cache, optional HTML with tooltips.

AI-powered template that clones any website into a clean Next.js app via a single command. Supports Claude Code, Cursor, Codex, Gemini, and more.
