Agent Skills Discovery RFC

Cloudflare's draft spec for publishing Agent Skills at a predictable URL — an index at /.well-known/agent-skills/ lists each skill as a single artifact with a type, a URL and a SHA-256 digest. Apache-2.0, v0.2.0, and a draft rather than a ratified IETF RFC.

binpatch

Binary delta-update engine from BYK. Publish a bsdiff+zstd patch next to each release and a self-updating binary walks the chain from the installed version to the target instead of downloading itself again. Zero runtime dependencies, MIT.

video-use

Edit video by chatting with a coding agent — drop raw takes in a folder, get a cut, graded, subtitled final.mp4 back. The model never watches the footage; it reads a word-level transcript and a rendered timeline.

Cloudflare OS

Cloudflare's internal AI productivity platform, open-sourced. Agents build "gadgets" — private per-user apps written from a prompt — and reach company systems through Gatekeepers, a capability-based permission layer.

Herdr

Open-source terminal multiplexer built for coding agents — run Claude Code, Codex, OpenCode and more from one terminal on any box, with persistent PTY sessions you can detach and reattach from any device, even a phone over SSH.

integrations.sh

A registry of 5,700+ integration specs from Rhys Sullivan — the same builder behind Executor. Every service normalized into MCP, OpenAPI, GraphQL, and CLI form, each surface leading with a grounded, cited credential guide agents can act on.

Eve

Open-source agent framework from Vercel — define agents as directories of TypeScript and Markdown config and deploy them as standard Vercel projects.

Flue

TypeScript framework for building durable AI agents and workflows with no vendor lock-in — write once, deploy anywhere, run on any LLM.

fff

The fastest and most accurate file search toolkit for AI agents, Neovim, Rust, C, and Node. Keeps an in-memory index for sub-10ms queries instead of spawning ripgrep/fzf per search.

Infisical

Open-source security platform for developers and AI agents — secrets management, certificate management (PKI), and privileged access (PAM) under a single identity model with unified auditing.

netxjs-monorepo

Opinionated Next.js + Turborepo starter with Biome linting, TypeScript, shadcn/ui, and pre-loaded Claude Code agent skills and hooks.

Mediabunny

TypeScript library for reading, writing, and converting media files directly in the browser — like FFmpeg, but for the web. Zero dependencies, tree-shakable, and hardware-accelerated via the WebCodecs API.

SEO Lens

Chrome extension that audits SEO metadata on any webpage with instant scoring, structured data validation, and AI-friendly copyable reports for Claude Code and Cursor.

tfjs-zero-to-hero

Re-implementing classic ML models in TypeScript with @tensorflow/tfjs-node, following Andrej Karpathy's Neural Networks. Zero to Hero. Final destination — a from-scratch two-tower retrieval model on MovieLens.

Executor

Open-source tool gateway for agents from Rhys Sullivan. Normalizes MCP, OpenAPI, GraphQL, and custom sources into one typed SDK that agents call in a sandbox — built on Cloudflare's Code Mode pattern.

Hex

Open-source, fully native macOS voice-to-text app using local Parakeet TDT v3 models with zero network calls. Press-and-hold a hotkey to record, release to paste the transcript anywhere.

Scira

Open-source agentic research platform that plans, retrieves, and returns cited answers across 17 search modes.

telegram-claude

Telegram bot interface for Claude Code on a VPS. Message the bot, it spawns Claude Code in the selected project directory and streams results back — voice notes, streaming responses, session continuity, plan-mode interception.

agent-browser

Rust CLI tool for browser automation designed for AI agent workflows with JSON output and screenshot support.

emulate

Local API emulator that provides stateful, production-fidelity stubs for services like GitHub, Google, and Slack.

just-bash

Simulated bash environment with a virtual filesystem for use in AI agent workflows.

portless

Replaces localhost port numbers with stable named URLs and enables HTTPS and HTTP/2 for local dev servers.

zero-native

Framework for building desktop and mobile apps with Zig backends and web frontends via platform WebViews.

VERT

Free, privacy-first file converter that runs entirely in the browser using WebAssembly. Supports images, videos, audio, documents, and more with no uploads required.

auto-pr

Local Node.js loop that turns GitHub issues into pull requests — label an issue `auto-pr` and a multi-step Claude pipeline (research → plan → implement → review) spawns Claude Code and opens a PR.
