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.

harness-doctor

Claude Code / Codex skill that mines the last N days of Claude Code transcripts across every project on the machine into five fact tables — bash, errors, tokens, human corrections, fan-out — and returns a ranked list of fixes with the measured number behind each one.

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.

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.

Effect Skill

Kit Langton's opinionated agent skill for building production TypeScript apps with Effect v4 — workflows, services, layers, schemas, config, schedules, caches, streams, HTTP clients, and tests, with current APIs and production defaults.

exe.dev

Cloud for you and your agents — disposable per-second sandboxes, persistent Linux VPS with SSH/HTTPS, and Devbox cloud dev environments.

context-doctor

Claude Code / Codex skill that audits the fixed context a coding agent auto-loads every session — tool/MCP definitions, connectors, plugins, skills, subagents, memory/rules files — and proposes ranked cuts to prune, gate, or route what's loaded but unused.

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.

memory-view

Claude Code / Codex skill that reads a project's auto-memory vault and generates a self-contained HTML explorer to visualize what the agent has remembered — MEMORY.md plus topic files — without editing or managing it.

session-report

Claude Code / Codex skill that generates a self-contained HTML report debugging what is in a session's context window and how every token is spent — context budget, retained thinking, the dumb-zone cutoff, loaded CLAUDE.md and skills, and full history.

It's Time To Rethink Everything

Theo Browne's CascadiaJS 2026 talk arguing that AI is a "new cloud moment" — just as the cloud removed the cost of provisioning servers, agents remove the cost of building, so the sacred rules of software (file systems, codebases, packages, git, deployment) are worth tearing down and rebuilding from first principles.

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.

teach

Matt Pocock's skill that turns a coding agent into a personal tutor — it builds a stateful learning workspace and designs lessons within your zone of proximal development to teach you any skill or concept over multiple sessions.

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.

netxjs-monorepo

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

deepsec

AI-powered vulnerability scanner that uses coding agents to perform deep security analysis of codebases — regex-based candidate matching followed by LLM-driven investigation, with support for distributed execution and PR diff review.

Learn Harness Engineering

A 12-lecture curriculum on building effective harnesses that enable AI agents to complete complex tasks reliably — covering architecture, state management, session continuity, and observability patterns.

npm-deps-cleanup

AI agent skill that audits and reduces JavaScript package dependency footprint — removes unused deps, deduplicates workspace versions, analyzes transitive closures, and applies e18e replacement recommendations. Works with npm, pnpm, Yarn, and Bun.

Using Claude Code: The Unreasonable Effectiveness of HTML

Thariq makes the case for HTML over Markdown as Claude Code's output format — richer visualizations, color, diagrams, and easier sharing once agents are the ones authoring and humans rarely hand-edit.

Pullfrog

AI PR review agent from Zod's creator. Dynamically scales effort, uses subagent swarms for large PRs, and runs inside GitHub Actions with batteries-included MCP tools.

quality-code

Rhys Sullivan's TypeScript coding skill — branded types, discriminated unions, end-to-end types, real tests over mocks, OpenTelemetry observability, and picking the right abstractions instead of premature ones.

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.

improve-codebase-architecture

Matt Pocock's skill for deepening modules — restructuring prototype code into something long-lived with cleaner layer dependencies and easier navigation.

React Doctor

Static analysis tool that evaluates React codebases across security, performance, correctness, and architecture, producing a health score with diagnostics.

Stagehand

Open-source SDK for building browser agents using natural language instructions instead of brittle selectors.

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.

agent-eval

Testing framework for measuring how well AI coding agents perform against your framework or configuration.

just-bash

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

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.
