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.

LiteRT-LM is Google AI Edge's production-grade open-source inference framework for running large language models directly on edge devices — Android phones, iPhones, web browsers via WebAssembly, and IoT hardware. It powers the on-device GenAI features in Chrome, Chromebook Plus, and Pixel Watch that Google launched alongside Gemma 4. The framework supports a wide model zoo including Gemma, Llama, Phi-4, and Qwen, with quantization pipelines that fit models onto hardware as constrained as a wearable. It also supports function calling and tool use, enabling lightweight agentic workflows without a cloud round-trip. A JavaScript API makes browser integration straightforward for web developers. LiteRT-LM represents Google's answer to Apple Intelligence's on-device approach — an open, cross-platform runtime rather than a proprietary stack. The fact that it's open-sourced means any developer can ship private, offline AI features without touching Google's servers, which matters enormously for healthcare, finance, and enterprise applications.
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.”
“A unified inference runtime across Android, iOS, browser, and IoT with function calling support is exactly what the edge AI ecosystem has been missing. The WebAssembly path alone opens up private on-device AI in any browser without installing anything. Ship this immediately.”
“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.”
“Edge inference is still severely constrained — even quantized Gemma 3B on a phone gives you a noticeably worse experience than cloud APIs. Google's history with edge AI frameworks is also mixed: TensorFlow Lite, ML Kit, MediaPipe all launched with fanfare and then got inconsistent maintenance.”
“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.”
“This is infrastructure for the next decade. When models run on-device with no latency and no data leaving the device, entirely new categories of ambient, private AI become possible. LiteRT-LM is the missing runtime layer for that world — and Google open-sourcing it means the ecosystem builds around it rather than around Apple.”
“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.”
“Offline AI for creative apps is a game-changer — imagine Procreate or Figma with on-device generative features that work on a plane. The browser WebAssembly support means I can prototype these ideas without an app store or backend. Very excited about the creative possibilities here.”
