io.github.PostHog/posthog/creating-box-plot-insights

Creates product analytics or SQL-backed box plot insights in PostHog. Use when a user asks to create, build, or save a box plot, visualize a numeric distribution, compare quartiles or medians across dates or groups, or turn SQL results into a box plot. Chooses between a standard Trends box plot and a SQL insight, validates the distribution data, saves the insight, and verifies it.

io.github.google/skills/google-mobile-ads-get-started

Provides instructions for integrating the Google Mobile Ads (GMA) SDK. Use this skill when the user wants to get started with, install, integrate, set up, or configure the SDK for AdMob or Ad Manager, GMA Next-Gen SDK or mobile ads framework in an Android, iOS, or Unity application.

io.github.openclaw/openclaw/openclaw-pr-maintainer

Use immediately for any pasted OpenClaw GitHub issue or PR URL/number, and for OpenClaw issue/PR orchestration, review, triage, root-cause repair, PR rewrite, duplicate search, opener identity/who wrote it, author account age/activity, comments, labels, close, land, or maintainer evidence checks.

io.github.vercel/next.js/next-cache-components-adoption

Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the `cacheComponents` flag, work through a flood of blocking-prerender / instant validation errors, run the `cache-components-instant-false` codemod, or decide between opting routes out with `export const instant = false` and fixing them in place.

io.github.PostHog/posthog/debugging-experiments

Debug and support PostHog Experiments (A/B tests) for a customer looking at their own results. Use whenever an experiment support ticket is pasted or a customer asks a results question, most commonly "why aren't my exposures even?", "why is one variant getting no traffic?", "why am I missing / seeing too few exposures?", "why does the bias banner show?", or "why don't PostHog's numbers match my SQL?". Pulls the experiment's real data read-only, matches it to a known-cause catalog, and produces a customer-facing explanation, fix, and review of the pertinent numbers. Loads diagnosing-experiment-results as its deep diagnostic library. DO NOT TRIGGER when: creating an experiment (use creating-experiments), only configuring rollout (configuring-experiment-rollout) or metrics (configuring-experiment-analytics), asking lifecycle questions (managing-experiment-lifecycle), or the underlying feature flag is what's misbehaving rather than the results (use debugging-feature-flags).

io.github.pytorch/pytorch/triaging-issues

Triages GitHub issues by routing to oncall teams, applying labels, and closing questions. Use when processing new PyTorch issues or when asked to triage an issue.

io.github.openclaw/openclaw/openclaw-changelog-update

Regenerate OpenClaw release changelog sections from git history before beta, stable, or extended-stable releases.

io.github.discourse/discourse/discourse-writing-typescript

Write TypeScript for Discourse core, plugins, and themes. Use when authoring new .ts/.gts files (components, modifiers, helpers, services, utils), typing an existing public API, or converting existing .js/.gjs files to .ts/.gts. Covers the component/modifier/plain-class Signature patterns, TSDoc for Signatures, typing untyped dependencies, compile-time type tests, the strict-grade bar under the loose global tsconfig, and the faithful-port and rename pitfalls that the type-checker does NOT catch.

io.github.discourse/discourse/discourse-frontend-conventions

Conventions for Discourse frontend code, JavaScript and TypeScript alike (.js/.gjs/.ts/.gts), in core, plugins, and themes that the linter does not enforce. Use when writing, reviewing, or preparing to commit class-based code or templates. Covers the private-symbols pattern (#, unprefixed, _), class member ordering beyond the lint buckets, blank lines before documented fields, no banner comments, safe in-template comments, attribute/argument/modifier ordering on invocations, and the comment necessity gate.

io.github.nextlevelbuilder/ui-ux-pro-max-skill/banner-design

Design banners for social media, ads, website heroes, creative assets, and print. Multiple art direction options with optional generated or supplied visuals. Actions: design, create, generate banner. Platforms: Facebook, Twitter/X, LinkedIn, YouTube, Instagram, Google Display, website hero, print. Styles: minimalist, gradient, bold typography, photo-based, illustrated, geometric, retro, glassmorphism, 3D, neon, duotone, editorial, collage.

io.github.PostHog/posthog/turning-engineering-analytics-into-insights

Converts engineering analytics (PR / CI) data into saved PostHog insights, dashboards, and subscriptions, and explains how to query the product data directly with SQL. Covers discovering per-team GitHub warehouse tables via engineering-analytics-sources, replicating curated column semantics in HogQL, reading exposed engineering_analytics_* warehouse views where product logic is involved (CI cost, fingerprinted failure lines, commit attribution), saving queries with insight-create, and scheduling delivery with subscriptions-create. Use when asked to "save this as an insight", "put CI health / merge times on a dashboard", "email me PR throughput weekly", "chart CI cost", "track time to first review", "subscribe to these numbers", "alert on CI success rate", or "what data/tables/views does engineering analytics read". For ad-hoc CI and merge questions use diagnosing-ci-and-merge-bottlenecks; to investigate one specific CI failure use investigating-ci-failures.

io.github.addyosmani/agent-skills/deprecation-and-migration

Manages deprecation and migration. Use when removing old systems, APIs, or features. Use when migrating users from one implementation to another. Use when migrating a database schema in production, such as renaming or dropping a column without downtime (expand/contract). Use when deciding whether to maintain or sunset existing code.

io.github.openclaw/openclaw/control-ui-e2e

Use when testing, fixing, or extending the OpenClaw Control UI GUI with Vitest + Playwright end-to-end checks, mocked Gateway WebSocket flows, mocked dashboard runs, screenshots/videos, or agent-verifiable browser proof.

io.github.logseq/logseq/libs

Build, debug, or review Logseq plugins with the `@logseq/libs` SDK (TypeScript/JavaScript, iframe/shadow sandboxed). Use when the task involves writing plugin entry code, registering slash/command/UI items, provideUI/provideStyle/provideModel, settings schema, macro renderers, DB-graph properties & tags, Datascript/DSL queries, experimental APIs, theme plugins, or the `logseq/*` CLJS facade generated under this package.

io.github.prisma/orm/publish-npm-version

Cuts the next release of Prisma 8: bumps the root package.json version (on the v8 RC line: 8.0.0-rc.N → rc.N+1), propagates it to every workspace package, and opens a PR titled "chore(release): bump to <next-version>". When the maintainer merges the PR, the `Publish to npm` workflow runs automatically and ships the new version to npm under the dist-tag its shape implies (`latest`; RC releases get a pre-release GitHub Release), plus a matching GitHub Release. Use when a maintainer asks to "cut the next RC", "cut the next release", "bump to the next version", "open a release PR", or "prepare a publish PR".

io.github.prisma/orm/ast-visitor-pattern

Use the frozen-class/visitor pattern for discriminated unions that have multiple dispatch sites. Use when creating a new set of variants (commands, IR nodes, factory calls) that will be switched over in 2+ places, or when refactoring an existing union type that has grown multiple switch sites.

io.github.PostHog/posthog/posthog-desktop

Scopes work to the desktop app at products/desktop — a nested standalone pnpm/turbo/Biome workspace imported from the now-archived PostHog/code repo, with posthog/posthog the only source of truth for PRs, CI and publishing, and not part of the root frontend or Django build. Use when the user says /posthog-desktop, or works on the Electron desktop app, apps/code, apps/web, apps/mobile, packages/core, packages/ui, packages/workspace-server, @posthog/api-client, @posthog/agent, or the agent framework. Pins the working directory to products/desktop, swaps in that tree's toolchain and conventions in place of the monorepo's, and defines the few paths outside the tree that may be touched (Django APIs the app calls, desktop-* CI at the root).

io.github.lobehub/lobehub/design-prototype

Produce an interactive single-file HTML design prototype using the REAL LobeHub design system (@lobehub/ui + antd + antd-style tokens) with production-style React — no build step, opens directly in a browser. Use when asked for a design prototype / interactive mockup / 交互原型 / 出个原型 / 设计稿 HTML for a page or flow, or to explore a redesign before committing to implementation.

io.github.supabase/supabase/explorer

Build and modify Studio Explorer surfaces, including notebooks, chats, SQL snippets, query cells, and their shared toolbar patterns.

io.github.openclaw/openclaw/openclaw-update

Route routine updates of an existing local or remote OpenClaw Gateway to its installation owner, with automatic session recovery. Defer to deployment-specific skills when available.

io.github.openclaw/openclaw/openclaw-repair-sweep

Orchestrate worker fleets over OpenClaw issues and PRs: prove root causes, prefer clean refactors over quick patches, land verified repairs, and close items proven fixed or no longer useful.

io.github.TriliumNext/Trilium/developing-standalone

Use when working on Trilium's standalone in-browser build (`apps/standalone`, deployed at app.triliumnotes.org and embedded by the mobile app) — the service worker (`sw.ts`), the leader-tab election and multi-tab request forwarding, the SQLite worker (`local-server-worker.ts`, `@sqlite.org/sqlite-wasm` on OPFS SAHPool), the `lightweight/*` provider implementations that `initializeCore()` needs in the browser, standalone-only routes, `window.standaloneApi`, backup/restore in OPFS, the Vite bundle stubs (officeparser, pdfjs, sqlite wasm copies), startup errors, or running/testing/deploying it. Also load it when a change to `packages/trilium-core` adds a provider, a Node import, or a top-level side effect — standalone is where that breaks.

io.github.browser-use/browser-use/cloud

Documentation reference for using Browser Use Cloud — the hosted API and SDK for browser automation. Use this skill whenever the user needs help with the Cloud REST API (v2, v3, or v4), browser-use-sdk (Python or TypeScript), X-Browser-Use-API-Key authentication, cloud sessions, browser profiles, profile sync, CDP WebSocket connections, stealth browsers, residential proxies, CAPTCHA handling, webhooks, workspaces, skills marketplace, liveUrl streaming, pricing, or integration patterns (chat UI, subagent, adding browser tools to existing agents). Also trigger for questions about n8n/Make/Zapier integration, Playwright/ Puppeteer/Selenium on cloud infrastructure, or 1Password vault integration. Do NOT use this for the open-source Python library (Agent, Browser, Tools config) — use the open-source skill instead.
