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.

Lovable 2.0 is an AI-native full-stack builder that generates complete web applications from natural language prompts, with v2.0 adding deep Supabase integration for instant backend provisioning, a visual component editor for in-context tweaks, and one-click custom domain publishing. It targets non-engineers and early-stage builders who want a working full-stack app without touching infrastructure config. The Supabase pairing means auth, database, and storage are wired automatically — not just scaffolded.
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.”
“The primitive here is: natural-language-to-deployed-full-stack-app, with Supabase as the opinionated backend layer — and that's actually a clean, nameable bet. The DX choice they made is right: hardcode the infrastructure opinion (Supabase), so the complexity budget goes into the generation quality, not into letting you pick your ORM. The moment of truth is whether the generated Supabase schema is sane — not just 'does it run' but 'would a developer not be embarrassed by it.' From the demos, it's passable but not clean; you'll still want to audit RLS policies. The weekend-alternative test is where this earns its keep: wiring Supabase auth + storage + a React frontend from scratch is a half-day of boilerplate even for experienced engineers. Lovable 2.0 ships that in minutes. Skip if you're an engineer building for production; ship if you're building an MVP that needs to not embarrass you at a demo.”
“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.”
“Category is AI app builder; direct competitors are Bolt.new, Replit Agent, and GitHub Copilot Workspace. Lovable's specific bet is the Supabase lock-in — unlike Bolt, they've committed to one backend provider and built the integration deep enough that auth and RLS actually wire up automatically. That's a real differentiation, not a bullet point. Where this breaks: any app that outgrows the generated schema. The moment a real engineer inherits a Lovable-generated codebase and needs to do a non-trivial migration, they're staring at spaghetti. The 12-month kill scenario is Supabase shipping their own AI builder natively — they have the distribution, the docs, and the relationship with the same user. What saves Lovable is if they build enough workflow stickiness before that happens, which is plausible but not guaranteed.”
“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.”
“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.”
“The buyer is a non-technical founder or a designer who wants to ship an MVP — they're spending personal money or early pre-seed budget, and the ceiling on that contract is low. The pricing architecture is fine at $25-50/mo but the expansion story is weak: power users outgrow Lovable and export to raw code, taking zero revenue with them. The moat question is where this gets uncomfortable — Supabase integration is a partnership, not a proprietary advantage, and Bolt.new or Replit can replicate it in a sprint. The business survives if the brand becomes synonymous with 'non-technical founder's first app' the way Squarespace owns 'small business website,' but that brand-as-moat is extremely expensive to build and defend. Until I see evidence of meaningful retention past the first shipped project, the unit economics don't convince me.”
“The job-to-be-done is crisp: 'I have an idea for a web app and I want it live with real auth and a real database before I talk to investors.' That's one job, it's real, and the Supabase integration makes it complete in a way v1 wasn't — you no longer need to leave the tool to wire up your backend. Onboarding reaches value fast: prompt in, app preview out, Supabase project auto-provisioned. The gap is the visual editor — it exists, but the editing surface for non-UI things (like schema changes after the fact) is underdeveloped, so users hit a wall the moment requirements evolve. This is a ship because it can replace the 'prototype in Figma, then hire a dev' workflow for early-stage products — that's a real substitution, not just a supplement. The opinion is strong: one stack, one backend, ship it.”
