Development
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.).
Build full-stack React applications with TanStack Start on Cloudflare Workers. Type-safe routing, server functions, SSR/streaming, and seamless D1/KV/R2 integration. Use when: building full-stack React apps, need SSR with Cloudflare Workers, want type-safe server functions, or migrating from Next.js. RC status - v1.0 stable pending. Monitor tanstack/router#5734 (memory leak) before production use.
Test-driven development execution workflow with red-green-refactor cycle, increment decomposition, and pause/continue rules. Use when building features or fixing bugs using TDD. Framework-agnostic with language-specific configs for Python, TypeScript, Go, and Ruby delegation.
Unified team skill for tech debt identification and remediation. Scans codebase for tech debt, assesses severity, plans and executes fixes with validation. Uses team-worker agent architecture with roles/ for domain logic. Coordinator orchestrates pipeline, workers are team-worker agents. Triggers on "team tech debt".
Technical debt detection and remediation. Run at session end to find duplicated code, dead imports, security issues, and complexity hotspots. Triggers: 'find tech debt', 'scan for issues', 'check code quality', 'wrap up session', 'ready to commit', 'before merge', 'code review prep'. Always uses parallel subagents for fast analysis.
Build VoIP calling apps on iOS using Telnyx WebRTC SDK. Covers authentication, making/receiving calls, CallKit integration, PushKit/APNS push notifications, call quality metrics, and AI Agent integration. Use when implementing real-time voice communication on iOS.
Use this skill when writing Go integration tests with Docker containers, using testcontainers-go modules (postgres, redis, kafka, etc.), setting up container-based test infrastructure, or configuring container networking and wait strategies. Covers 62+ pre-configured modules, cleanup patterns, and multi-container setups.
Execute an approved directory of dependency-linked Markdown tickets as a tested integration branch — bounded fresh workers, senior-guide/junior-implementer pairing for risky tickets, risk-based review, deterministic Git integration, resumable run state. Executes approved tickets; never authors them.
Spec-to-task lifecycle manager for AI coding agents. Interviews user to resolve ambiguities, decomposes specs into atomic tasks, manages execution order via dependency graph, and batch-closes with evidence. Use when user wants to implement a spec, plan tasks, decompose a feature, a *.tasks.json file exists, or user says 'continue with tp' to resume work after a context clear.
Expert guidance for tRPC (TypeScript Remote Procedure Call) including router setup, procedures, middleware, context, client configuration, and Next.js integration. Use this when building type-safe APIs, integrating tRPC with Next.js, or implementing client-server communication with full TypeScript inference.
Enhance JSDoc annotations for TypeScript code to optimize AI comprehension. Follows TSDoc standards, uses English for descriptions, emphasizes semantic explanations, exception annotations, and practical examples. Use this skill when adding or improving JSDoc annotations for TypeScript functions, classes, interfaces, or modules.
UE5.6-UE5.8 save/load and multiplayer replication workflow for gameplay systems. Use when requests involve SaveGame schema design, serialization, restore pipelines, RepNotify handling, RPC entry points, and server-authoritative validation.
Use when working with concrete utility components in BK-CI, such as JWT, security authentication, expression parsing, thread pool loop utilities, and chain-of-responsibility implementations. Prefer this when the user wants to reuse these components directly rather than design framework-level practices.
Valaxy static blog framework built with Vue 3, Vite, and pnpm workspaces. Use when working with Valaxy projects: (1) creating or configuring Valaxy blog sites (site.config.ts, valaxy.config.ts), (2) writing blog posts with frontmatter, (3) developing Valaxy themes (valaxy-theme-*), (4) developing Valaxy addons (valaxy-addon-*), (5) customizing components/layouts/styles, (6) working with the Valaxy monorepo core framework, (7) debugging Valaxy builds or dev server, (8) deploying Valaxy sites. Triggers on: valaxy.config.ts, site.config.ts, theme.config.ts, defineValaxyConfig, defineSiteConfig, defineThemeConfig, defineTheme, defineAddon, valaxy-theme-*, valaxy-addon-*, pages/posts/, ValaxyMain, useSiteConfig, useFrontmatter, #valaxy/config.
Velt Notifications implementation patterns and best practices for React, Next.js, and web applications. Use when adding in-app notifications, notification panels, email notifications via SendGrid, webhook integrations, user notification preference management, cross-organization notification feeds with enableCrossOrganization/disableCrossOrganization, or binding Notifications Panel / Notifications Tool wireframe slots with template variables (velt-data, velt-if, velt-class).
Integrate Redis-compatible Vercel KV for caching, session management, and rate limiting in Next.js applications. Powered by Upstash with strong consistency and TTL support. Use when implementing cache strategies, storing temporary data with expiration, building rate limiters, or troubleshooting missing environment variables, serialization errors, or rate limit issues.
בונה אוטומטית סוכן וואטסאפ חכם בעברית עם Kapso (WhatsApp Business), Gemini (LLM + tools), ו-Maton (Google Calendar / Zoom / Gmail / כל אינטגרציה). פורס ל-Vercel, מגדיר webhooks, מסנכרן ENV — בלי שאתה צריך לגעת בקונסול. השתמש בסקיל בכל פעם שמישהו מבקש: "בנה לי בוט וואטסאפ", "סוכן וואטסאפ", "WhatsApp agent", "תקבע פגישות מהוואטסאפ", או רוצה לחבר Kapso + Gemini + Maton יחד.
Use for 'why does X work this way', 'why we picked Y', design rationale, regressions, postmortems, or data-backed thresholds. Discovers available MCPs and queries each evidence category (source control, issue tracker, long-form docs, real-time chat, infrastructure observability, error tracking, product analytics warehouse) in parallel, then returns a cited read on decisions and tradeoffs. Use how for runtime behavior.
Audit a fixed cohort of inactive WooCommerce pull requests against current trunk, linked issues, review history, repository labels, and representative user flows, then produce evidence-backed actions and a private checklist report. Use for stale or backlog PR cohort reviews, not ordinary single-PR code review.
Create or update a User Story. Use when you need to create, document, update, or standardize user stories. Activate when the user requests a new user story, describes a functional need, asks to refine requirements, structure features, or align existing stories with the project's conventions.
Implement already-specified work in code, of four types: (1) technical tasks (TK-XXX) under a user story; (2) maintenance tasks (WI-XXX) without a story — bugs, refactoring, technical debt, dependencies, operations; (3) test cases (TC-XXX) — automate the tests already documented by test-define; (4) features (FT-XXX) — automate the TCs of their acceptance criteria. Select the type according to the referenced artifact. Only implement work in State: Ready; it also accepts a bounded correction mode, delegated by quality-check, on any artifact of the branch (US-XXX, WI-XXX, FT-XXX, TC-XXX on a test/ branch, or an artifact external to the plugin), to fix a failing check or test. Always activate when the user asks to "implement", "develop", "execute tasks", "code", "automate the tests", "implement the test cases", "work on the TK/WI/TC/FT", or variants implying writing code from an already-drafted specification.
Close and integrate the work of a user story (US-XXX), a maintenance task (WI-XXX), or a test automation (test/ branch on a US-XXX, WI-XXX, or FT-XXX) by merging the branch into the branch it was created from, after verifying that progress.md has all work units in Done and that the closing quality gates pass (quality-check, code-review, and trace-validate). Activate when the user asks to close, deliver, merge, integrate, finish, or submit the work of a story, a WI, a feature, or the current branch.
ALWAYS LOAD THIS SKILL WHEN WRITING OR EDITING PYTHON CODE. Do not write or modify Python files directly — use this skill first. Core Python standards: basedpyright strict typing, Result-based error handling, async patterns, security, code style.
Generate lightweight technical specification documents with PlantUML diagrams. Use this skill whenever the user asks to design a feature, plan an implementation, document architecture changes, specify database schema changes, describe API endpoints, or needs to capture WHAT changes across services - even if they don't explicitly say "tech spec" or "specification".
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.
