This repository is a meticulously crafted template for using AI coding agents to reverse-engineer live websites into clean, modern Next.js codebases. It provides a pre-configured Next.js 16 scaffold (with shadcn/ui, Tailwind v4, and TypeScript strict) alongside a sophisticated set of agent instructions that guide the AI through the entire cloning process: mapping URLs, observing the target, building components, and comparing results. The project is not just a code scaffold; it is a complete workflow definition designed for Claude Code, Codex, Cursor, and OpenCode. The architecture is elegantly split between the application scaffold (src/, public/) and the agent skill definitions (.agents/skills/clone-website/). The canonical skill (SKILL.md) and its references (inspection-guide.md, framer-and-motion.md) represent a masterclass in prompt engineering, providing concrete, actionable guidance for handling complex scenarios like Framer-generated pages, scroll-driven animations, and responsive asset extraction. The project structure enforces clean separation of concerns for multiple cloned sites. The codebase demonstrates exceptional craftsmanship and a deep understanding of both software engineering and AI agent capabilities. The highlighted components—the agent skills, the token-counting CI workflow, and the cross-platform agent configuration—are genuinely reusable patterns that solve non-obvious problems. This is a rare example of a template that is more valuable for its workflow and documentation than its application code, setting a high standard for AI-assisted development projects. Maintenance is active, technical drift is low, and the project is a strong 9.0 on the quality scale.
Headroom is a context optimization layer for LLM applications that reduces token usage by 50-90% through intelligent compression, caching, and memory systems. It provides a transparent proxy between LLM clients (like Claude Code, Cursor, etc.) and LLM providers (Anthropic, OpenAI, etc.), implementing CCR (Compress-Cache-Retrieve) for lossless compression with retrieval capability. The system features a hybrid polyglot architecture with a Rust-based high-performance proxy core, Python ecosystem for extensibility, and TypeScript SDK. Key capabilities include agent wrapping, cross-agent memory using Qdrant/Neo4j, observability through metrics and dashboard, and a learning system that analyzes interaction patterns to generate optimization rules. Deployment options include Docker, system services, and direct execution.
Humanizer is a skill (prompt) for AI agents that rewrites AI-generated text to sound human-written without altering factual content. It is built on Wikipedia's 'Signs of AI writing' guide and provides 26 numbered patterns grouped into six categories (staging, rhythm, inflation, formatting, leftovers, wrong reader). The skill is distributed as a single markdown file (SKILL.md) with YAML metadata, installable via plugin manifests for Claude Code, Cursor, and other agents through the Skills CLI. The repository also includes a validation script, issue templates, and CI workflows to maintain consistency across package files. While not a traditional software application, it functions as a tool that agents execute, with clear entry points (/humanizer command) and a well-defined workflow (mark tells, draft rewrite, check, finalize). The codebase is meticulously maintained with active issue triage, regular releases, and automated validation.
This repository is a production-grade meta-framework for building and managing AI agent plugins across multiple coding assistants (Claude Code, Codex, Cursor, OpenCode, Gemini, Copilot). It establishes a single source of truth in Markdown (`plugins/`) that is compiled into harness-specific artifacts via Python adapters. Key features include a security layer using Cedar policies for tool-call authorization and signed audit receipts, a project management system (`conductor`) for track-based development, and a quality evaluation framework (`plugin-eval`) using static analysis and LLM-based scoring. It solves the fragmentation problem of AI agent ecosystems by enforcing portability and governance.
The ai-boost/awesome-prompts repository is a curated collection of prompt templates designed to configure AI agents for specific roles and tasks. It contains hundreds of specialized prompts for agent architectures (e.g., personal agent brains, multi-agent orchestrators), agent skills (e.g., coding agents, security auditors), and domain-specific agents (e.g., healthcare operations, legal analysts). Each prompt encapsulates non-obvious design patterns for agent systems, such as three-layer retrieval for memory, plan-execute loops, declarative UIs, and skill-based architectures. The repository serves as a reference for prompt engineering and agent design, enabling users to build reliable, safe, and effective LLM-based agents without starting from scratch.
MLflow is an open-source ML lifecycle platform that provides experiment tracking, model registry, model deployment, evaluation, and observability for both classical ML and GenAI/LLM workflows. In production, it operates as a modular monolith: a Python backend (Flask/FastAPI) with SQLAlchemy-backed storage (SQLite, PostgreSQL, MySQL, MSSQL), a React/TypeScript web UI, and client SDKs for Python, R, Java, and TypeScript. The system exposes a REST API and CLI for logging experiments, registering models, collecting traces via OpenTelemetry, and managing an AI Gateway that routes requests to dozens of LLM providers with budget controls, guardrails, and traffic splitting. The architecture includes a plugin system for custom store backends, deployment targets, and authentication providers, as well as a custom linting tool (clint) and extensive CI/CD pipelines. Key entry points are the `mlflow` CLI, `MlflowClient` Python API, tracking server (`mlflow server`), gateway server (`mlflow gateway`), and model scoring server (`mlflow models serve`). Data flows from user instrumentation through asynchronous logging to the backend store, with traces and evaluations queryable via the UI or API. External dependencies span ML frameworks (scikit-learn, PyTorch, TensorFlow, LangChain, etc.), LLM provider SDKs, and infrastructure tools (Docker, Kubernetes, Helm).
Langfuse is an open-source LLM observability and evaluation platform. It provides tracing, prompt management, evaluations, datasets, experiments, monitors, and a public API for integrating with AI applications. The architecture is a monorepo with pnpm workspaces and Turborepo, consisting of a Next.js frontend (web), a background worker (Express + BullMQ), a shared package with types and server utilities, and an enterprise edition. Data flows from ingestion (REST API, OpenTelemetry, SDKs) into ClickHouse for high-volume analytics and PostgreSQL for relational metadata. Background jobs handle evaluations, batch exports, cloud billing, and integrations. The codebase is well-structured with extensive testing, a custom ESLint plugin, and reusable UI components. It is actively maintained with frequent migrations and feature additions.
Patina is a deterministic, pattern-based AI text detection and humanization tool, primarily targeting Korean but supporting English, Chinese, and Japanese. It operates as a Node.js CLI (`patina-cli`), a web API (Vercel serverless), and an agent skill (Claude Code, Codex, Cursor). The core workflow: analyze source text for AI-typical patterns (stylometry, lexicon, discourse tells), build a structured prompt, invoke an LLM backend (OpenAI, Claude, Gemini, Kimi, etc.), verify meaning preservation (MPS/fidelity), and output a humanized rewrite with a deterministic audit trail. It enforces strict meaning guards (number safety, polarity, causation) and provides scoring, diff, and verification modes. The architecture is modular: a shared deterministic analysis core (`src/features/`) runs identically in Node and browser; a prompt builder assembles context from pattern packs, document types, and personas; multiple backend adapters abstract LLM invocation; and a verification pipeline ensures fidelity. The project includes extensive research infrastructure (benchmarking, human evaluation panels, corpus management) and a commercial Pro tier with Polar license validation. It is well-tested with over 200 unit/e2e tests, CI/CD, and security hardening (SSRF guards, input fencing, atomic writes).
This repository is a meta-application: a curated, opinionated framework of prompts ('skills') designed to govern the behavior of AI coding agents like Claude Code and GitHub Copilot Codex. It does not contain traditional application code but instead defines a structured software development methodology executed by an AI agent. The system transforms an AI agent from a simple chat interface into a disciplined, stateful development partner that plans, implements, reviews, and maintains code according to explicit workflows. The architecture is a monolith of interdependent markdown files organized into a skill hierarchy. The `ask-matt` skill acts as a router, directing user requests to the appropriate workflow. Core primitives like `grilling` (structured interview) and `domain-modeling` (glossary/ADR creation) are reused by higher-level skills. Execution engines like `implement` and `code-review` drive the actual development cycle. A key innovation is the 'stateful workspace' pattern, where the agent writes decisions to files (GLOSSARY.md, ADRs, specs) to maintain context across sessions and manage token limits. The codebase demonstrates exceptionally high craftsmanship in prompt engineering, with clear patterns for context management, sub-agent delegation, and human-in-the-loop interaction. It is actively maintained with a detailed changelog. However, its complexity is a double-edged sword: the tight coupling between skills and the reliance on specific model behavior creates a fragile ecosystem. The documented open bugs and high cognitive load for users are significant risks, preventing it from achieving an 'exceptional' rating despite its innovative design. The repository is a brilliant but brittle system for professional AI-assisted development.
Caveman is a multi-agent AI coding skill/plugin that compresses LLM output tokens by ~65-75% using a 'caveman' terse communication style. It's not a library or service but a distributed configuration package that installs into 30+ AI coding agents (Claude Code, Codex, Gemini, Cursor, Windsurf, Cline, Copilot, opencode, OpenClaw, etc.) through their native plugin/extension/rule-file mechanisms. The core deliverable is a set of SKILL.md prompt files that instruct models to drop articles, filler, pleasantries, and hedging while preserving exact technical substance, code blocks, URLs, and paths. The architecture is a single Node.js installer (bin/install.js) that auto-detects installed agents and dispatches to per-provider installation paths. For Claude Code specifically, it adds SessionStart and UserPromptSubmit hooks plus a statusline badge. The repo includes several sub-skills: caveman-commit (terse conventional commits), caveman-review (one-line PR comments), caveman-compress (rewrites memory files like CLAUDE.md into caveman format to save input tokens), caveman-stats (reads session logs to report real token savings), and cavecrew (compressed subagent definitions for investigator/builder/reviewer patterns). There's also caveman-shrink, an MCP middleware proxy that compresses tool descriptions. The codebase demonstrates strong engineering practices: symlink-safe flag file writes with O_NOFOLLOW and ownership verification, atomic settings.json merges with JSONC tolerance, defensive hook validation before writes, idempotent install/uninstall cycles, and a three-arm eval harness (baseline/terse/skill) for honest token compression measurement. The Python compress tool has safety guards against exfiltrating sensitive files and verifies backup integrity before overwriting. Test coverage is substantial across installer e2e flows, hook symlink safety, opencode plugin lifecycle, and config resolution order.
This repository defines a reusable AI agent skill for role-playing as Zhang Xuefeng, a Chinese education influencer. The core artifact is SKILL.md, a meticulously crafted markdown file with YAML frontmatter that encodes five mental models, eight decision heuristics, a complete expression DNA, and an agentic workflow (research → analyze → respond). It is not a running service or library; it is a configuration file consumed by compatible agent runtimes (Claude Code, Codex, Cursor, etc.) to transform the agent's behavior. The repository also includes six research files (references/research/) that document the persona's writings, conversations, expression style, external views, decisions, and timeline, serving as the evidence base for the skill. The skill demonstrates advanced prompt engineering, cognitive modeling, and agentic protocol design, making it a high-quality example of the Agent Skills pattern. It is actively maintained and has no technical drift as it consists solely of static markdown files.
This repository is a meticulously curated knowledge base and toolkit for AI video prompt engineering. Its core is a structured data pipeline: raw knowledge from official vendor documentation and YouTube masterclasses is reverse-engineered into standardized methodologies (21+ SOPs) and a centralized prompt database (`prompts/data/all-prompts.json`). This data is then exposed through a cross-model benchmark (`prompts/data/cross-model-matrix.json`), zero-dependency web tools (Prompt Browser, Cross-Model Matrix), and executable Claude Code Skills (`skills/`). The architecture is data-centric. The primary value lies in the curated, structured data assets and the rigorous methodology used to create them. The application layer (web tools, skills) is a thin, well-crafted consumer of this data. The repository actively manages its primary risk—model version drift—through an automated monitoring system (`scripts/monitor_models.py`) that hashes external endpoints and files issues on change. While primarily a data_research project, it exhibits strong application characteristics through its interactive tools and AI skill integrations. It is a living knowledge base, actively maintained with a clear contribution workflow and a strong emphasis on data provenance and reproducibility. The `cross-model-matrix.json` is a standout asset, providing a controlled benchmark for comparing prompt styles across 11 major AI video models.
Fabric is an open-source framework for augmenting humans using AI, centered on a large library of crowdsourced prompt templates called 'patterns'. The system provides a CLI tool, a REST API server, and a SvelteKit web UI, all sharing a common pattern engine that applies structured prompts to user input (text, URLs, YouTube videos, PDFs, images). The architecture is modular: a plugin registry manages AI vendor adapters (OpenAI, Anthropic, Gemini, Ollama, Azure, Bedrock, Vertex AI, and 25+ OpenAI-compatible providers), a template engine supports variable substitution and executable extensions, and a filesystem-backed storage layer handles patterns, sessions, and contexts with path-traversal protection. Key entry points include the Go CLI (`cmd/fabric`), the Gin-based REST API (`internal/server`), and the SvelteKit web app (`web/`). External dependencies span multiple AI SDKs, web scraping libraries (go-readability), YouTube transcription (yt-dlp), and SQLite for caching. The pattern library itself is a data asset with over 100 markdown files, each defining identity, steps, and output instructions for tasks like summarization, analysis, code review, and creative writing.
Kiln AI is a full-stack, local-first AI development platform for building, evaluating, and iterating on LLM-based systems. It provides a desktop application (FastAPI server + SvelteKit web UI) and a core Python library (published on PyPI) that together enable users to define tasks, run models via LiteLLM across 190+ providers, evaluate outputs with a rich framework (LLM-as-judge, programmatic checks, code evals), fine-tune models, generate synthetic data, manage RAG pipelines (chunking, embedding, vector stores, reranking), and integrate tools (MCP, code tools, skills). The architecture is a monolith with a local server serving a single-page web app, with all data stored on the local filesystem and optionally synced to Git. The codebase is well-structured with clean abstractions, extensive test coverage (unit, integration, e2e with Playwright), and several reusable patterns (sandboxed code execution, git sync middleware, job system, eval plugin architecture). While primarily an application, it includes significant data/research capabilities for synthetic data generation and evaluation.
Taste-skill is not a software application in the traditional sense; it is a portable library of AI-agent 'skills' - extremely detailed Markdown instruction files (SKILL.md) distributed via the `npx skills add` CLI (Vercel agent-skills spec) and a .claude-plugin marketplace. The repo's product is the prompt content itself: 13 frontend design-direction skills that agents like Claude Code, Codex, and ChatGPT load to avoid generic 'AI slop' output. The flagship is `taste-skill` v2 (`design-taste-frontend`), a ~5000-line instruction document that codifies anti-pattern bans (zero em-dashes, no section-number eyebrows, no three-equal-card rows), a brief-inference protocol, design-system mapping to official packages (Fluent, Carbon, Polaris, GOV.UK), canonical GSAP/scroll-reactive code skeletons, and a hard pre-flight checklist with mechanical pass/fail criteria. It is complemented by image-generation-only skills (brandkit, imagegen-frontend-web/mobile) that produce reference comps for downstream coding agents, plus variant skills (brutalist, minimalist, soft, stitch, output-enforcement). The repository also contains a `research/laziness/` folder documenting LLM output-truncation causes and remediation, and a small set of Node/Sharp image-processing scripts used to build the README assets. Those scripts contain one genuinely valuable, extractable algorithm: a flood-fill outer-background removal with auto-cropping to content bounds. The scripts are one-off (hardcoded `C:/Users/User/Downloads` source paths, tightly coupled to specific sponsor assets), so they are not drop-in reusable without adaptation, but the background-removal technique itself is portable. This is a content/instruction repository rather than a codebase; software-engineering quality bars (tests, CI) do not apply. Its craftsmanship lives in the rigor, specificity, and mechanical enforcement of the prompt files, which is exceptional for the prompt-engineering domain. The active development cadence, current dependency references (Tailwind v4, Motion/react, React Server Components), and 92k-star traction confirm it is the leading project in its niche.
This repository is a collection of specialized 'Skills' for the Claude AI assistant, each designed to enhance Claude's capabilities for specific professional tasks. The McKinsey Consultant Skill implements McKinsey's Problem Solving methodology to guide users through structured business analysis and generate professional PowerPoint presentations. The Mimeng Writing Skill helps create viral Chinese-style articles by encoding specific writing techniques. The Find-session Skill assists in locating and resuming specific Claude Code conversations through grep-based search of conversation history. The US Government Shutdown Tracker Skill fetches and analyzes economic data from the FRED API to assess liquidity impacts of government shutdowns, generating visualizations and status assessments. The repository demonstrates thoughtful architecture, particularly in the McKinsey Consultant Skill's progressive disclosure approach to manage Claude's context limitations, and contains several reusable components for PPT styling, economic data analysis, and visualization.
This repository, named 'AI Short' (ChatGPT-Shortcut), is a production-grade Docusaurus-based web application that serves as a curated, multilingual library of over 5,000 AI prompts for ChatGPT, Gemini, Claude, and similar tools. The application provides a searchable, tag-filterable interface with prompt cards, copy-with-tracking, and detailed pages featuring FAQs and related prompts. It supports 18 languages via separate Docusaurus builds and includes a browser extension (Chrome/Firefox) for quick access. Beyond the static prompt data, it offers a community platform with user accounts (OAuth), favorites, custom prompt creation, voting, comments, and a level system. The frontend is a React 19 SPA with Ant Design 6, featuring client-side caching, optimistic UI updates, and lazy-loaded components. The backend (Strapi) is not open-sourced but the API contracts are fully defined. Deployment options include standard (shared backend), offline (localStorage), and full self-hosted setups. The code demonstrates strong engineering practices: clean component decomposition, custom hooks for data management, a two-tier cache system with ETag support, and thoughtful accessibility patterns. The prompt data itself is static JSON, generated from a master file via a Python pipeline, and includes rich metadata for SEO and cross-referencing.
Ponytail is a skill ecosystem for AI coding agents that enforces a 'lazy senior developer' mindset through a priority ladder: YAGNI, reuse existing code, prefer stdlib/native features, avoid unrequested abstractions, and write minimal working code. It delivers this via platform-specific adapters (hooks, command files, plugin manifests) for agents like Claude Code, Codex, GitHub Copilot, OpenCode, Gemini CLI, and others. The core skill definition lives in skills/ponytail/SKILL.md, with companion skills for review, audit, debt tracking, gain scoring, and help. The system includes automated validation scripts to maintain consistency across platform-specific rule copies and version manifests, benchmark suites to measure code/token/cost reductions, and test coverage for hook behavior and plugin integrity.
Liza is a disciplined multi-agent orchestration system for AI-assisted software development. It manages a pipeline of roles (orchestrator, coder, reviewer, architect) that collaborate via a behavioral contract enforced by deterministic Go code. The system provides a CLI (Cobra) and a Bubbletea TUI, with a YAML-based state file (blackboard) for persistence, Git worktree isolation per task, and a state-machine task lifecycle (planning → implementation → review → merge). It integrates with multiple LLM providers (Claude, Codex, Gemini, etc.) via their CLIs or the Agent Context Protocol (ACP). The architecture follows a clean layered design: `cmd/liza/` contains CLI commands, `internal/commands/` are thin adapters, `internal/ops/` holds core business logic (claiming, submitting, reviewing, merging, recovering), `internal/models/` defines domain types, and `internal/db/` manages the blackboard. The system is heavily test-covered with unit, integration, and lifecycle replay tests. It also includes optional codebase indexing via SCIP, Stacklit, and Semble for improved context. Key features include generation-fenced agent authority, circuit breaker anomaly detection, sprint metrics, checkpoint summaries, automated dependency repair, and pre-commit hooks. The repository is well-documented with extensive ADRs, architecture diagrams, and skill definitions. While the codebase is large and has some platform-specific code (Windows support), it demonstrates high craftsmanship in its use of idempotent lifecycle receipts, file-locking primitives, and error classification.
This repository is a full-stack Next.js application that serves as the world's largest open-source prompt library for AI. It provides a platform for users to create, share, discover, and manage prompts for various AI models (ChatGPT, Claude, Gemini, etc.). The core functionality includes CRUD operations for prompts with types (text, image, video, audio, skill, taste), voting, commenting, versioning, change requests, collections, and moderation tools. It features AI-powered capabilities such as semantic search via OpenAI embeddings, prompt improvement, translation, quality checking, and media generation through plugin-based providers (Fal.ai, Wiro.ai). The application supports multi-tenancy for self-hosting with configurable branding, authentication plugins (OAuth, OIDC, GitHub, Apple, Google), and storage backends (S3, DO Spaces). Beyond the web app, it includes a CLI tool (packages/prompts.chat) for browsing and running prompts locally, a Raycast extension for quick access, and an MCP server for integration with AI coding assistants. Additionally, it bundles an interactive educational book on prompt engineering (28+ chapters) and a gamified kids learning section, both fully localized into 17 languages. The codebase is well-structured with a plugin registry pattern, configuration-driven design, and extensive use of modern Next.js patterns (App Router, server components, streaming).
