Forkcast Today #3: claude-plugins-official, codegraph, andrej-karpathy-skills, skills

Episode Summary#

This episode explores four projects shaping how developers work with AI coding agents. Anthropic’s official plugin registry standardizes agent extensibility, a code knowledge graph enables semantic codebase understanding, Andrej Karpathy’s influential skills file enforces structured thinking, and Matt Pocock’s engineering skills collection brings production-grade discipline to AI-assisted development.

Repositories Covered#

claude-plugins-official#

Anthropic’s official plugin registry for Claude Code. Standardizes plugin structure with three extension mechanisms — Skills, Commands, and MCP Servers — including 30+ first-party plugins for LSP support, PR review, and code quality.

codegraph#

A pre-indexed code knowledge graph for Claude Code, Codex, Cursor, and OpenCode. Provides local semantic indexing and graph traversal that dramatically reduces file scanning and tool calls across large multi-language codebases.

andrej-karpathy-skills#

A Claude Code plugin implementing four principles from Andrej Karpathy’s LLM coding observations: think before coding, simplicity first, surgical changes, and goal-driven execution. Forces the agent to state assumptions and define success criteria before writing code.

skills#

A collection of production-grade engineering skills for AI coding agents by Matt Pocock. Provides structured, reusable capability files that make agents more reliable at TypeScript, testing, and general software engineering tasks.

superpowers#

An agentic skills framework and software development methodology that enforces TDD, spec-first workflows, git worktree isolation, and two-stage code review. With 200K+ stars, it defines how AI coding agents should work reliably across Claude Code, Codex, Cursor, and more.

CLI-Anything#

Auto-generates command-line interfaces for any software, making it controllable by AI agents.

OpenWA#

Free, Open Source, Self-Hosted WhatsApp API Gateway

chrome-devtools-mcp#

AI coding agents can write code but can’t see what happens in the browser — they’re blind to layout bugs, console errors, network failures, and performance issues 42+ tools across 10+ categories (input, navigation, debugging, performance, network, memory, extensions, emulation), built on Puppeteer, 47 releases, 829 commits, v0.25.0 (May 2026), integrates with 19+ MCP clients (Claude Code, Cursor, Copilot, Gemini CLI, Windsurf, etc.), Chrome 144+ for auto-connect, Node.js 20.19+, Apache 2.0

ai-engineering-from-scratch#

Learn it. Build it. Ship it for others.

notebooklm-py#

Unofficial Python API and agentic skill for Google NotebookLM

oh-my-pi#

AI Coding agent for the terminal

forge#

Guardrails that take an 8B parameter model from 53% to 99% accuracy on agentic tasks. Implements structured output validation, tool-use constraints, and safety filters that dramatically improve small model reliability for autonomous agent workflows.

multica#

The open-source managed agents platform

academic-research-skills#

Academic Research Skills for Claude Code: research → write → review → revise → finalize

the-book-of-secret-knowledge#

A collection of inspiring lists, manuals, cheatsheets, blogs, hacks, one-liners, cli/web tools and more.

streambert#

A cross-platform Electron Desktop App to stream and download any Movie, TV Series or Anime

agency-agents#

Generic ‘act as a developer’ prompts produce mediocre output — production work needs specialized AI agents with personality, proven processes, and domain expertise. 144+ specialized agents across 12 divisions (Engineering, Design, Paid Media, Sales, Marketing), 10,000+ lines of content, 11 tool integrations (Claude Code, Copilot, Cursor, Gemini CLI, Aider, Windsurf), multi-agent example deploys 8 agents simultaneously.

s-ui#

An advanced Web Panel • Built for SagerNet/Sing-Box

Understand-Anything#

The #1 trending GitHub project that transforms any codebase into an interactive, searchable, Q&A-ready knowledge graph. Built with TypeScript, it integrates with every major AI coding agent and makes legacy code instantly understandable.

Bindu#

A self-hosted media discovery and recommendation engine. Helps you find, organize, and discover new content across your media library with AI-powered suggestions that respect your privacy.

openhuman#

A local-first personal AI assistant with memory tree, Obsidian wiki integration, 118+ third-party integrations, and TokenJuice compression. Runs with Rust, React, and Tauri for a native desktop experience.

codex#

Lightweight coding agent that runs in your terminal

ghostty#

Fast, feature-rich, cross-platform terminal emulator with GPU acceleration
