Development
Guide the creation of high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when the user wants to build an MCP server to integrate an external API or service, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Migrates projects from Intercom to Gleap. Detects Intercom SDK integration (JavaScript, iOS, Android, React Native, Flutter), removes it, installs the Gleap SDK, and replaces all Intercom API calls with Gleap equivalents. Also covers server-side REST API migration. Use when switching from Intercom to Gleap, replacing Intercom, or migrating away from Intercom.
Guide users from zero to their first working mirrord session — check system requirements, install mirrord via CLI, VS Code, or IntelliJ, run a first session against a Kubernetes target, and verify the connection. Use when a user is new to mirrord, wants to install it, needs help running their first session, or wants to debug or test a local process against their Kubernetes cluster.
Next.js 15+ App Router development patterns including Server Components, Client Components, data fetching, layouts, and server actions. Use when creating pages, routes, layouts, components, API route handlers, server actions, loading states, error boundaries, or working with Next.js navigation and metadata.
Analyze git diff/pull request changes to detect feature implementations and fixes, extract acceptance criteria, and identify related tickets. Use this skill when the user wants to understand what changed in a PR/branch, determine if it's a feature or bug fix, and get acceptance criteria for manual test case generation.
Python design patterns including KISS, Separation of Concerns, Single Responsibility, and composition over inheritance. Use when making architecture decisions, refactoring code structure, or evaluating when abstractions are appropriate.
Official Rails documentation. Use when asked about any Rails-specific topic including ActiveRecord, routing, controllers, views, mailers, jobs, Action Cable, Action Text, Active Storage, migrations, validations, callbacks, associations, caching, security, or internals.
Use when a React Native app uses or is choosing the react-native-video library — playing/controlling video or audio, the v6 `Video` component or the v7 `useVideoPlayer`/`VideoView` player API, source/props/events (onLoad, onProgress, onEnd, paused, resizeMode, source, drm), HLS/DASH, DRM (Widevine/FairPlay, `@react-native-video/drm`), captions/tracks, Picture-in-Picture, background or lockscreen audio, fullscreen, buffering, offline/downloading, or native iOS/Android setup; also when deciding between v6 and v7 or migrating between them. Triggers on "react-native-video", "RNV", `Video`, `useVideoPlayer`, `VideoView`, and similar.
Redis + Redisson caching and distributed locking skill. Covers cache key naming conventions, TTL setting principles, RedisTemplate serialization choices (JSON vs JDK vs String), the three Redisson distributed lock modes (watchDog / tryLock with leaseTime / without leaseTime decisions), cache penetration (bloom filter / null value caching) / breakdown (mutex) / avalanche (random TTL) protection, and Caffeine vs Redis selection decisions. Corrects LLM mistakes: not setting a TTL, mixing StringRedisTemplate and RedisTemplate, Redisson locks without try-finally unlock, and the watchdog not taking effect when a leaseTime is specified.
Generate changelog entries and GitHub releases from git history. Categorizes commits into features, fixes, breaking changes, and docs. Supports conventional commits, PR-based grouping, and semantic versioning. Creates formatted CHANGELOG.md entries and GitHub releases.

Test Riverpod providers and widgets; ProviderContainer.test, unit tests, widget tests with ProviderScope, tester.container(), mocking with overrides, container.listen for auto-dispose, awaiting .future. Use when writing unit or widget tests for Riverpod code, mocking providers, or testing with overrides. Use this skill when the user asks about testing Riverpod, mocking providers, or ProviderContainer in tests.
Look up the official Roblox creator documentation (Engine API + creator guides) and get back an accurate, cited summary. This is a tool for YOU, the agent — not just the user. Reach for it proactively: whenever you are even slightly unsure about a Roblox/Luau API (a class, method, property, event, datatype, enum, global, library, service, or Studio feature), whenever you need deeper knowledge than you can confidently recall, and whenever you want to compare or explore alternative APIs for a task. Especially use it while PLANNING Roblox work — before committing to an approach — to ground your assumptions in real docs instead of guessing. Roblox's API changes often, so prefer verifying here over answering from memory; it is the reliable way to avoid hallucinated or outdated API signatures. Triggers on any Roblox or Luau development task, even when the user never says "docs".
ROS 2 engineering: rclcpp/rclpy, colcon/ament, launch, QoS/DDS, tf2/URDF, ros2_control, Nav2, MoveIt 2, sensors, runtime/artifact provenance, and hardware safety. Use for development, review, debugging, and ROS 1 migration to ROS 2. Not for general C++/Python, unrelated middleware, or web/mobile tasks.
Plan, execute, audit, and verify behavior-preserving migrations from Java Maven or Gradle projects to project-shaped Rust Cargo workspaces, including derived crate boundaries, scale-appropriate topology, 100% lossless source-test/case migration, byte-identical test assets, and complete per-case differential parity. Use when comparing repositories at module, package, object, file, method, parameter, documentation, example, test, fixture/data, dependency-reuse, JavaBean/script-property, concurrency, runtime-behavior, oversized Rust-file, or test-organization level; producing migration documents; continuing an incomplete port; or repairing workspace drift. Enforces source-authoritative inventories, Rust-native APIs, a 500-line cohesion-review threshold and 800-line authored-file blocker, idiomatic unit/integration test placement, strict non-completion states, frozen baselines, and unified verification.
Pre-push hygiene check for GitHub repositories. Scans for PII, secrets, and sensitive data before pushing. Audits commit messages, enforces repo-specific blocklists, and rate-limits pushes to avoid GitHub abuse detection. Use before any git push, especially to public repos.
Generate n8n workflows that use the official ScraperAPI community node (n8n-nodes-scraperapi-official).

Write Tailwind CSS following practices that keep a fast-to-write codebase maintainable — use design tokens instead of magic values, keep class lists short, group tokens semantically, generate classes in consistent order, avoid @apply for extracting repeated styles, and use fixed variants instead of arbitrary className props. Use this whenever writing or editing Tailwind classes, components, or config, and also when reviewing, cleaning up, refactoring, or auditing an existing Tailwind project. Do NOT use for general CSS architecture unrelated to Tailwind, or for build tooling unrelated to CSS output (bundlers, JS minification, etc.).
