Development
Create, update, validate, and submit Homebrew Casks (macOS and Linux/AppImage). Use when the user mentions Homebrew cask/cask, Homebrew/homebrew-cask, adding a new cask, updating or bumping a cask, cask token naming, generate-cask-token, sha256, livecheck, zap/uninstall, AppImage/app_image, on_linux/on_macos, cross-platform cask, or when asked to run brew style, brew audit or brew lgtm for a cask.
Build production-quality search experiences (autocomplete, search results pages, faceted search) using InstantSearch. Use when user asks to add search, autocomplete, search-as-you-type, faceted filtering, or a search results page to a React, Vue, or vanilla JS application, or mentions Algolia, InstantSearch, or react-instantsearch. Do NOT use for backend index operations (records, synonyms, settings, API keys), use algolia-cli instead. Do NOT use for analytics, recommendations, or MCP server queries, use algolia-mcp instead. Do NOT use for AI/agent/conversational search, use algobot-cli instead.
Use when something is too slow, uses too much memory or CPU, degrades under load, or times out — and before making any change intended to speed something up. Triggers include "this is slow", "optimize this", "high latency", "p99", "memory leak", "it's fine locally but not in production", "the query takes forever", "reduce bundle size", and any request to make code faster.
Kotlin Multiplatform structure and language traps: module splits, expect/actual, Koin and ViewModel scoping, layers, version catalogs, erased overloads, Char and string-resource formatting limits. Use when shaping modules or DI, when a format specifier renders verbatim, or code misbehaves on one platform
Analyze official Megatron-LM commits, PRs, and branch change sets to identify feature evolution, candidate breaking changes, and migration-relevant events. Use when Codex already has a normalized Megatron change set and needs to explain what changed, which new features matter, and which changes should flow into MindSpeed adaptation work.
Track and normalize change requests against the official Megatron-LM repository by branch, PR, commit, commit range, or time window. Use when Codex needs to collect the exact upstream change set before deeper analysis, especially for branch-aware Megatron and MindSpeed migration work, daily/periodic tracking, or preparing inputs for change analysis and migration generation.
Map migration-relevant Megatron changes onto the official MindSpeed repository by resolving branch alignment, locating affected subsystems, and identifying concrete adaptation points. Use when Codex has structured Megatron change events and needs to decide whether MindSpeed already covers them, which MindSpeed files are likely affected, and whether patch generation is safe.
A UI motion reference library that helps you add suitable animations to your product. No need to understand motion design — describe your product scenario (slow page load, no response after a user clicks, wanting the page to feel more polished) and get a recommended approach plus code. Trigger phrases: 页面没动画、交互没反馈、怎么加动效、让页面动起来、加载太慢怎么办、想让产品高级一点、motion ref.
Triage a daily msverl regression run by reading the baseline comparison log, stopping on success, extracting the most relevant training failure evidence from the daily training log when needed, collecting recent commits from verl main and MindSpeed master, and ranking the most likely culprit commits with concise fix-direction guidance.
Next.js 16 App Router pages mixing static and dynamic content — Partial Prerendering (PPR) under the Cache Components model. Covers enabling it with cacheComponents (the removed experimental.ppr / experimental_ppr flags), the dynamic-by-default rendering inversion, the Suspense static-shell/dynamic-hole boundary, the 'use cache' directive (automatic keys, cacheLife/cacheTag, children/action pass-through, runtime values as props, serverless durability), async runtime APIs and connection() for non-determinism, page composition from a single hole to parallel dashboards to streaming a Promise into a Client Component with use(), and forms/wizards with updateTag read-your-writes and Activity state preservation. Triggers on PPR, cacheComponents, 'use cache', Suspense streaming, partial prerendering, or static-shell work even when not named explicitly.
Sets up and configures Hookdeck Outpost for outbound event delivery to customer endpoints. Use when sending webhooks to customers, building webhook delivery infrastructure, managing tenants and destinations with supported types (webhooks, Hookdeck Event Gateway, AWS SQS/Kinesis/S3, Azure Service Bus, GCP Pub/Sub, RabbitMQ, Kafka), or aligning topics and publishes. EventBridge support is tracked in GitHub issues.
The CLI for the public API directory at postman.com/explore — search, rank, and watch community-contributed Postman Collections, agent-native and offline. Trigger phrases: `find a postman collection for`, `what postman collection should i fork for`, `is there a postman collection for`, `browse postman api network`, `compare postman publishers`, `what changed on the postman network`, `use postman-explore`, `run postman-explore`.
Zero-config goal-to-tasks engine (the Atlas engine). Takes any goal (software, pentest, business, learning), runs adaptive discovery via brainstorming, generates a validated spec, parses into TaskMaster tasks, and hands off to execution. Use when user says "PRD", "product requirements", "I want to build", invokes /atlas, or wants task-driven development.
Comprehensive skill for Product Managers to create organize and manage Product Teams, Strategy, PRDs, release plans, user stories, and standalone issues with high-quality acceptance criteria. Supports both full documentation workflows (PRD → Plan → Stories) and quick issue creation (standalone stories, tasks, bugs). All documentation follows design-driven development principles with functional, testable acceptance criteria based on visual designs and user flows.
Best practices for Remotion - Video creation in React. Use when creating programmatic videos with Remotion, adding animations or transitions, working with audio/captions, rendering compositions, embedding 3D content, building charts, or using Mapbox maps in video.
Design, implement, test, and operate resilient Rust outbound HTTP clients with reqwest, hyper, Tower middleware, connection pooling, DNS, proxies, TLS, redirects, deadlines, retries, rate and concurrency limits, streaming bodies, cancellation, SSRF controls, and mock or real-server contract tests. Use when users ask to call REST APIs, download or upload data, configure an HTTP client, diagnose connection failures, or harden service-to-service requests; keep inbound servers in rust-web.
Build UIs with Tailwind CSS v4 and shadcn/ui. Covers CSS variables with OKLCH colors, component variants with CVA, responsive design, dark mode, and Tailwind v4.2 features. Supports Radix UI and Base UI primitives, CLI 3.0, and visual styles. Use when building interfaces with Tailwind, styling shadcn/ui components, implementing themes, or working with utility-first CSS. Triggers on tailwind, shadcn, utility classes, CSS variables, OKLCH, component styling, theming, dark mode, radix ui.
Use this skill whenever writing new code, proposing a bugfix, reviewing a PR/diff, or discussing whether to add an abstraction, config layer, plugin system, or generic mechanism. Also trigger for architecture/design discussions, "is this too complex" questions, or any point where Claude is about to suggest introducing a new abstraction layer. The core stance — code is written for humans to read, not as an artwork to admire — optimize for affordance (like a road sign, instantly readable) rather than elegance or cleverness. Trigger even if the user doesn't name "simplicity" explicitly — e.g. "should I make this configurable", "quick fix for this bug", "review this PR", "should I abstract this into a helper", "this codebase feels messy". DO NOT USE for one-shot factual questions, pure formatting/typo edits, or when the user explicitly asks for a generic/configurable design.
Receive and verify Slack Events API webhooks. Use when setting up Slack webhook handlers, debugging Slack signature verification, handling the url_verification challenge, or processing events like app_mention, message, reaction_added, team_join, or app_home_opened.
Connect to the Superset MCP server to create Git-worktree workspaces, launch coding-agent sessions, schedule automations, and manage tasks on a user's Superset account. Use when an agent needs to orchestrate parallel coding agents programmatically over MCP instead of the CLI.
Task tracking and implementation execution for swain projects. Invoke whenever a SPEC needs an implementation plan, the user asks what to work on next, wants to check or update task status, claim or close tasks, manage dependencies, abandon work, bookmark context, or record a decision. Also invoked by swain-design after creating a SPEC that's ready for implementation. Tracks SPECs and SPIKEs — not EPICs, VISIONs, or JOURNEYs directly (those get decomposed into SPECs first). Triggers also on: 'bookmark', 'remember where I am', 'record decision'.
Set up Tailwind v4 with shadcn/ui using @theme inline pattern and CSS variable architecture. Four-step mandatory pattern: define CSS variables at root, map to Tailwind utilities, apply base styles, get automatic dark mode. Use when: initializing React projects with Tailwind v4, setting up shadcn/ui dark mode, or fixing colors not working, theme not applying, CSS variables broken, tw-animate-css errors, or migrating from v3.
Set up tRPC with TanStack Query in Next.js App Router projects. Use when: (1) Setting up tRPC from scratch in a Next.js project, (2) Adding new routers or procedures, (3) Integrating authentication with tRPC context, (4) Using tRPC with React Server Components, (5) Configuring prefetching and hydration patterns.
Advanced TypeScript type system specialist for complex generics, conditional types, template literals, type inference, performance optimization, and type-level programming. Use for intricate type system challenges, recursive types, brand types, utility type authoring, and type performance issues. Includes comprehensive coverage of 18 advanced type system error patterns.
Configures Unlayer's email, page, popup, and document builders — feature flags, appearance, theming, merge tags, design tags, display conditions, special links, HMAC security, file storage, image uploads, localization, custom fonts, and validation. For the standalone Image Editor, use unlayer-image-editor.
Add impact and feedback effects to a Three.js game with lightweight particle bursts — muzzle flashes, hit sparks, blood/dust, explosions, pickups — using pooled additive sprites or Points. Use when actions need visible punch (firing, impacts, deaths, explosions) or for ambient effects (smoke, embers, dust).
Set up webhook receivers with signature verification, idempotent event processing, retry handling, and dead letter queues for reliable event-driven integrations. Use when the user requests webhook setup or provides relevant inputs for this workflow.
Structures large initiatives into a decomposed backlog with roadmap, dependencies, and verification. Generates an overview file plus individual story files with tasks. Use when work requires several coordinated stories, has dependencies between deliveries, or needs a roadmap.
Build interactive, click-through architecture diagrams for software systems — a self-contained single HTML file with animated step-by-step flows, mode toggles (dev/prod, offline/online, v1/v2), dark/light theme, and a side panel with payload details, plus a companion markdown description. Use when the user wants to visualize or design a system: architecture diagram, service map, data flow, RAG/agentic flow, microservices topology, integration diagram, CI/CD or data/ETL pipeline, multi-agent system, or onboarding diagram — or to design a new service's flows before building. Natural-language triggers: 'I'm building X, what should the flow look like', 'pokaż jak działa system', 'diagram architektury', 'wizualizacja systemu', 'klikany diagram'. Do NOT use for static diagrams that belong inline (Mermaid/PlantUML), slide decks, or printable/PDF handouts — this produces interactive HTML for browser consumption.
Use when writing or updating any Bagisto documentation site — the developer documentation, the merchant user guide, or any other Bagisto docs repository — covering page content, code samples, screenshots, the sidebar, image naming, and moving or deleting pages. Trigger phrases include "docs", "documentation", "user guide", "developer documentation", "dev docs", "merchant documentation", "marketplace docs", "document this", "update the docs", "add a doc page", "screenshot", "ImagePopup", "redirect a doc page".
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
