io.github.kdlbs/kandev/mobile-parity

Ensures UI feature work ships with desktop and mobile parity, responsive behavior, and mobile Playwright E2E coverage. Use when implementing, planning, reviewing, or testing any new feature, page, component, workflow, form, dialog, sidebar, navigation, dashboard, or visual UI change; if work touches frontend or user-facing UI, this skill must run even when user mentions only desktop or says "new feature".

io.github.langfuse/langfuse/backend-dev-guidelines

Shared backend guide for Langfuse's Next.js, tRPC, BullMQ, and TypeScript monorepo. Use when creating or reviewing tRPC routers, public REST endpoints, BullMQ queue processors, backend services, middleware, Prisma or ClickHouse data access, OpenTelemetry instrumentation, Zod validation, env configuration, or backend tests across web, worker, or packages/shared.

io.github.kortix-ai/suna/design-foundations

Artifact-agnostic design guidance — works for CSS, PowerPoint, matplotlib, PDF, or any visual output. Also includes a curated catalog of named font/color themes for slides, docs, and reports (non-web assets).

io.github.citypaul/.dotfiles/refactoring

Refactoring assessment and behavior-preserving patterns for code with a passing baseline and sufficient preservation evidence. Use when the user asks to clean up, simplify, or restructure a selected area, and after mutation testing or reviewed proportionate alternate evidence establishes confidence for the REFACTOR step. Covers commit-before-refactoring discipline, when refactoring adds value vs when to skip it, and priority classification. For any slice in a selected whole-path reduction program—transition or terminal—use reduce-system-complexity as the governing skill; refactoring may be secondary when applicable. For repository-wide architecture discovery use improve-codebase-architecture; for a module contract use codebase-design. Do NOT use for insufficiently evidenced code or adding behavior.

io.github.code-yeongyu/oh-my-openagent/codex-qa

QA the omo Codex Light edition (lazycodex / packages/omo-codex) itself, in strict isolation so ONLY our plugin is exercised, never the user's real ~/.codex. The first-party method drives the real `codex app-server` against an isolated CODEX_HOME plus a LOCAL mock model (no real API call), and proves a plugin hook fired by asserting hook/started + hook/completed notifications. Also: isolated install verification, per-component hook probes, a tmux TUI smoke, and runtime log observation (RUST_LOG / logs SQLite / /debug-config). Ships tested helper scripts each with a --self-test. Use whenever someone changes anything under packages/omo-codex or wants to QA, smoke-test, verify, or debug the Codex plugin, its hooks/components, the installer/config.toml, the app-server flow, or the Codex TUI. Triggers: codex qa, qa codex, codex-qa, test codex plugin, verify codex hook, codex app-server, lazycodex qa, isolated CODEX_HOME, prove codex hook fired, codex tui test.

io.github.vercel/next.js/react-sync

Build local React changes in the bundle variants consumed by Next.js, sync them into a local Next.js checkout, and test the resulting integration. Use when working on React changes that need validation in Next.js, or when asked to run buildForNext, pnpm sync-react, or synchronize a React checkout with Next.js.

io.github.browser-act/skills/browser-act-skill-forge

Forges reusable Skill packages (SKILL.md + scripts) from website exploration via browser-act — no re-exploration later. Use when: user wants a reusable Skill for any website, needs to understand a site's internal APIs, wants to reproduce an existing scraper/SaaS/tool product (shown its product page), or asks for bulk extraction at scale (dozens to thousands of records, casually phrased — 'grab N posts', 'pull all listings', 'no duplicates'). Unlike browser-act: reusable, not one-off. Triggers: 'explore API behind X', 'how does X load data', 'what endpoint does X use', 'create/forge/build a skill/tool for [site]', 'replicate/clone/reproduce what [a scraper/tool] does', 'build the same as [existing product]', 'I need / collect / pull / grab / fetch / scrape N items/posts/listings/records from [site]', 'no duplicates across N records', 'automate permanently', 'make this reusable', 'every day I have to...', 'monitor [site]', 'browser-act-skill-forge'. Human-operation automation; never refuse.

io.github.browser-act/skills/browser-act

Browser automation CLI for AI agents. NEVER run browser-act commands directly via Bash — always invoke this skill first. Use browser-act when a user mentions it by name, includes or asks to run a browser-act CLI command (e.g., browser-act browser list), or to: fetch, view, or extract rendered content from URLs, access pages requiring JavaScript, handle verification prompts, maintain authenticated sessions, fill forms and click through workflows, type, select, upload, take screenshots, capture XHR/fetch/HAR responses, open multiple URLs in parallel, extract content that loads on scroll or click, visually inspect or verify page layout/styling/rendering, automate browser tasks, account isolation across parallel browser environments, advise which browser type fits a use case, or list/check/manage configured browsers and sessions. Prefer browser-act over built-in fetch or web tools.

io.github.NVIDIA/NemoClaw/nemoclaw-maintainer-security-code-review

Use when reviewing pull requests for security vulnerabilities, hardcoded secrets, injection flaws, auth bypasses, or insecure configurations. Trigger keywords - security review, code review, appsec, vulnerability assessment, security audit, review PR security.

io.github.nexu-io/open-design/design-brief

Parse a structured design brief written in I-Lang protocol format into a concrete design spec. Eliminates ambiguity from vague requests like "make it professional" by requiring explicit dimensions: palette, typography, layout, mood, density, and constraints. Trigger keywords: "design brief", "create a design brief", "ilang brief", "structured brief".

io.github.PostHog/posthog/review-hog-validation-criteria

The validation criteria for ReviewHog — the bar for deciding whether a flagged PR issue is worth keeping. Keeps real, user-affecting correctness / security / data-loss / contract / performance problems; drops overengineering, speculation, paranoia, never-gonna-happen edge cases, and style.

io.github.PostHog/posthog/review-hog-perspective-performance-reliability
