agent-skills is a structured library of 20 production-grade engineering skills for AI coding agents, published by Addy Osmani (former Google Chrome DevTools lead, author of Essential JavaScript Design Patterns). It provides a complete spec-to-ship workflow via 7 slash commands (/spec, /plan, /build, /test, /review, /code-simplify, /ship) that work across Claude Code, Cursor, Gemini CLI, Windsurf, and GitHub Copilot — any agent that supports CLAUDE.md or equivalent configuration files. The library includes three specialist personas that activate on demand: a security auditor (checks for injection vulnerabilities, hardcoded secrets, OWASP Top 10), a code reviewer (focuses on maintainability, complexity, and test coverage), and a test engineer (generates unit, integration, and edge-case tests). Four reference checklists (API design, accessibility, performance, deployment) give agents shared evaluation criteria. Each skill is written as a Markdown instruction file following the CLAUDE.md conventions popularized by the karpathy-skills library. agent-skills accumulated 6,693 GitHub stars in its first trending week, outpacing most comparable skill collections. Osmani's framing — treating agent skills as a first-class engineering asset rather than ad-hoc prompts — resonates with teams trying to standardize how they use AI coding tools. The library is MIT-licensed and designed to be forked and extended.

Craft Agents OSS is a free, Apache-licensed desktop app and CLI framework for building and running AI agents against real-world workflows. Built by the team behind the Craft.do document editor, it connects to 32+ integrations out of the box — MCP servers, REST APIs, Google Workspace, Slack, GitHub, and local filesystems — with no manual configuration required. It supports Anthropic, OpenAI, Google AI, and any OpenAI-compatible backend in a single unified UI. The core idea is an "agent canvas" where users drag tools onto a timeline, set up triggers, and watch agents execute multi-step workflows in real time. It also ships a headless server mode, making it usable as a remote agent runner in CI/CD pipelines or staging environments. The project hit 4,200+ stars on GitHub within 24 hours of launch. What distinguishes Craft Agents from similar tools like Dify or n8n is its desktop-first UX and tight integration with Claude's computer-use and agent loop capabilities. The Craft team has deep product experience — this isn't a weekend hack but a polished tool with well-documented agent primitives, error handling, and rate limiting built in from day one.
Reviewer scorecard
“Having security audits, test generation, and spec creation as first-class slash commands changes how you think about agent-assisted development. The cross-tool compatibility (Claude, Cursor, Gemini) means you can standardize across a team with mixed tool preferences. Fork it, customize the checklists, and you have a company playbook.”
“This is the missing middle layer between raw SDK calls and fully managed platforms. 32 integrations with zero config and a headless mode means you can drop it into an existing workflow in under an hour. Apache 2.0 license is the cherry on top.”
“This is well-packaged prompt engineering, not a fundamentally new capability. The value depends entirely on the underlying agent following instructions reliably — which varies wildly across tools and models. Teams that haven't established basic code review processes will use this as a crutch rather than building genuine engineering discipline.”
“The 4k stars in 24 hours is impressive but hype-fueled. We've seen a dozen 'universal agent frameworks' launch in the last year — most get abandoned once the novelty wears off. Wait to see if the integration library is actively maintained before betting your workflows on it.”
“The real innovation here is treating agent behavior as versionable, shareable code. The next step is organizations maintaining their own agent-skills forks as living engineering standards — the CLAUDE.md pattern is becoming a de facto org-level configuration layer for how teams interact with AI.”
“Desktop-native agent runners are the 2026 equivalent of the browser as the universal platform. The Craft team's product pedigree and the open-source architecture mean this could become the go-to scaffolding for agent apps the way Electron became the default for desktop apps.”
“The /spec and /plan commands are genuinely useful for non-engineers who need to communicate feature requirements to an AI agent. Clear structured specs reduce the back-and-forth of vague prompts — this could be the bridge between product thinking and implementation.”
“Finally, an agent tool designed by people who actually care about UX. The drag-and-drop canvas is the first agent builder I've used that didn't feel like configuring XML. Non-engineers on my team were running their own agents in about 20 minutes.”
