Evidence-based assessment of whether an SAP API/interface usage scenario aligns with the SAP API Policy (v.4.2026a). Use whenever someone asks whether a way of calling SAP is allowed or compliant—for example, Published API vs internal/private/"confidential" API status, "Documented Use", whether a third-party tool / iPaaS / middleware / RPA bot / AI agent / MCP server may call SAP APIs, agentic or generative-AI access to SAP, bulk data extraction or replication into a lake/warehouse, custom Z/Y OData or RFC/BAPI wrappers and Clean Core, ADT/developer-tooling boundaries, ODP-RFC and other "not permitted" interfaces, partner Integration Certification, or RISE integration remediation. Trigger even when the policy is not named, e.g. "are we allowed to…", "is it compliant to…", "can we connect X to SAP…", "will this break under the new API policy". Produces a sourced technical assessment with a confidence level—explicitly NOT legal advice and NOT a final SAP compliance decision.
Create and refactor HTML5/JavaScript web designs from specifications or descriptions. Generates complete, accessible, responsive web designs with modern frameworks. Automatically verifies designs using Playwright MCP for accessibility and functionality testing. Use this skill when users ask to create web designs, mockups, landing pages, web applications, or refactor existing HTML/CSS/JS designs.
Reference standards for writing pull request titles and descriptions in the tldraw repository, plus the pre-flight comment sweep over the diff. Use as supporting guidance when another skill or workflow needs PR content standards, not as the user-facing create/update PR workflow.
Implement and debug React Native or Expo motion with Reanimated 4 and Gesture Handler 3: state transitions, layout, gestures, scroll, worklets, cancellation, and accessible alternatives. Use for native UI motion, not web Motion or a reason to add canvas graphics to ordinary views.
Use when someone wants a design system built from the UI an app already ships, or one phase of it, such as “extract tokens from the app”, “add states to our Button”, “replace the hardcoded colors with tokens” or “start a design system”. Moving screens onto an existing system's components is migrate-design-system. A vague whole-app ask goes to design-system-boss.
React feature-based architecture guidelines for scalable applications. Use this skill when writing, reviewing, or refactoring React code to ensure proper feature organization. When invoked on a project, the agent produces a concrete target-architecture blueprint at docs/architecture/FEATURE-ARCH-TARGET.md showing the desired directory tree, per-feature public APIs, import-boundary matrix, and a numbered migration plan. Triggers on tasks involving project structure, feature organization, module boundaries, cross-feature imports, data fetching patterns, or component composition.
Expert patterns for Godot AutoLoad (singleton) architecture including global state management, scene transitions, signal-based communication, dependency injection, autoload initialization order, and anti-patterns to avoid. Use for game managers, save systems, audio controllers, or cross-scene resources. Trigger keywords: AutoLoad, singleton, GameManager, SceneTransitioner, SaveManager, global_state, autoload_order, signal_bus, dependency_injection.
Expert blueprint for TileMapLayer and TileSet systems for efficient 2D level design. Covers terrain autotiling, physics layers, custom data, navigation integration, and runtime manipulation. Use when building grid-based levels OR implementing destructible tiles. Keywords TileMapLayer, TileSet, terrain, autotiling, atlas, physics layer, custom data.
Use this skill when users want to train or fine-tune language models using TRL (Transformer Reinforcement Learning) on Hugging Face Jobs infrastructure. Covers SFT, DPO, GRPO, and reward modeling training methods, plus GGUF conversion for local deployment. Includes guidance on the TRL Jobs package, UV scripts with PEP 723 format, dataset preparation and validation, hardware selection, cost estimation, Trackio monitoring, Hub authentication, and model persistence. Use for cloud GPU training, GGUF conversion, or when users mention training on Hugging Face Jobs without a local GPU setup.
Implement, migrate, design, review, and troubleshoot haptic feedback with Software Mansion Pulsar across React Native, iOS, Android, Kotlin Multiplatform, Flutter, and Web. Use when the user names Pulsar; a Pulsar package such as react-native-pulsar, com.swmansion:pulsar, com.swmansion:pulsar-kmp, pulsar_haptics, or pulsar-haptics; a Pulsar import, preset, composer, setting, installation, migration, or runtime problem; a Figma design carrying Pulsar haptic bindings; or explicitly requests migration to Pulsar. Do not use for generic haptics, vibration, Core Haptics, browser Vibration API, expo-haptics, animation, audio, motion, or UI-polish work without Pulsar evidence or explicit Pulsar intent
Set up, repair, and build components with NativeWind v4 and Tailwind CSS v3 in Expo React Native apps. Use for an explicitly v4 project, v4 configuration failures, className interoperability, or v4 theming; not for NativeWind v5 or generic web Tailwind setup.

Migrate projects from Bootstrap 5 to Bootstrap 6. Use when upgrading from Bootstrap 5, migrating v5 to v6, or updating v5 class names, components, Sass, or JavaScript to the latest version. For Bootstrap 4 projects, start with the v4-to-v6 migration skill instead.
Integrate the Dynatrace Flutter Plugin into a Flutter project — dependency setup, config, SDK bootstrap, navigation tracking, and verification. Trigger: "add Dynatrace to Flutter", "Flutter plugin setup", "instrument Flutter app", "integrate Dynatrace Flutter", "mobile observability Flutter", "dynatrace_flutter_plugin". Do NOT use for: querying Flutter RUM data (use dt-obs-frontends), non-Flutter mobile setups, or Dynatrace server-side configuration.
Expert debugging and profiling for leaks, GPU/Visual Profiler, headless CI QA, orphan nodes, thread-safe logs, and custom Debugger monitors — not print/breakpoint tutorials. Trigger on OBJECT_ORPHAN_NODE_COUNT, ObjectDB growth, Visual Profiler GPU spikes, flaky headless exits, or remote device consoles. Keywords: orphan nodes, Performance.get_monitor, Visual Profiler, Time.get_ticks_usec, EditorDebuggerPlugin, headless QA, push_error, backtrace.

Use the Bailian CLI (`bl`) to complete the full “data → fine-tuning → export → deployment → invocation” workflow, or skip training and deploy a base model directly. Supports fine-tuning text models (SFT/DPO/CPT), audio TTS models (CosyVoice), image generation models (Wan2.7), and video generation models (Wan i2v/kf2v). Covers dataset validation/upload, creating fine-tuning jobs, waiting for training, exporting the best checkpoint, creating inference deployments, waiting for readiness, and providing invocation examples. Activate this skill when the user mentions “training a model,” “fine-tuning,” “fine-tune,” “finetune,” “deploying a model,” “launching a model,” “running/invoking a fine-tuned model,” “training an inference model,” “continued pretraining,” “LoRA/SFT/DPO training,” “speech synthesis model,” “TTS fine-tuning,” “CosyVoice,” “voice cloning,” “image generation fine-tuning,” “text-to-image,” “image-to-image,” “Wan2.7,” “image model training,” “video generation fine-tuning,” “image-to-video,” “first-frame-to-video,” “first-and-last-frame,” “kf2v,” “i2v,” “Wan video,” or “video effects training” on Bailian / DashScope / Alibaba Cloud Model Studio. Use it even if the user does not explicitly say “use bl,” as long as they intend to train or deploy on Bailian; do not assemble commands yourself.
Spin up a working LiveAvatar demo from a curated catalog—clones the reference repo, installs dependencies, provisions the LiveAvatar account, and fills the env file, then hands off the parts only a human can do. Use when: (1) User wants to try, test, see, or demo LiveAvatar, (2) User asks what LiveAvatar demos or examples exist, (3) User wants a sales agent / lead-qualification avatar, (4) User wants a LiveKit agent driving a LiveAvatar avatar, (5) User wants an avatar joining their own LiveKit room, (6) User wants a speech-to-speech avatar, a GPT-Live demo, a language-learning or tutor avatar, a customer-support avatar, a poker coach / game-style avatar, or an avatar with on-screen visuals/overlays, (7) User says "run the LiveAvatar demo", "show me LiveAvatar", "get me started with LiveAvatar", or "clone the LiveAvatar example", (8) User is evaluating LiveAvatar and wants something running before writing their own integration.
Nuxt UI v4 component library for building Nuxt v4 applications. 125+ accessible components with Tailwind v4, Reka UI, dark mode, theming. Use for dashboards, forms, overlays, editors, page layouts, pricing pages, or encountering component, theming, or TypeScript errors.
Code-reviews Pluggy API integrations against Pluggy's official documentation (queried in real time via the Pluggy MCP, with a web fallback to docs.pluggy.ai when the MCP isn't connected) and returns a diagnostic report (✅/❌/⚠️) with file, line, and the code fix for each issue. Use WHENEVER the dev uploads integration files and asks to review, analyze, diagnose, or validate their Pluggy integration — or says things like "review my integration", "check my Pluggy code", "is this ready for production?", "Pluggy Doctor", "check my webhooks", "is my integration secure?", or the Portuguese variants "analisa minha integração", "revisa meu código da Pluggy", "tá tudo certo pra ir pra produção?", "checa meus webhooks", "minha integração tá segura?". Also trigger when the dev pastes/uploads code that clearly calls the Pluggy API (connect_token, GET /items, item/created webhooks, clientUserId, etc.) and wants to know if it's correct, even without saying "Pluggy Doctor". This skill is for REVIEWING existing code, not writing an integration from scratch.
Workflow automation is the infrastructure that makes AI agents reliable. Without durable execution, a network hiccup during a 10-step payment flow means lost money and angry customers. With it, workflows resume exactly where they left off. This skill covers the platforms (n8n, Temporal, Inngest) and patterns (sequential, parallel, orchestrator-worker) that turn brittle scripts into production-grade automation. Key insight: The platforms make different tradeoffs. n8n optimizes for accessibility
Build autonomous AI agents with Claude Agent SDK. Structured outputs guarantee JSON schema validation, with a plugins system and hooks for event-driven workflows. Prevents 14 documented errors. Use when: building coding agents, SRE systems, security auditors, or troubleshooting CLI not found, structured output validation, session forking errors, MCP config issues, subagent cleanup
Analyzes git diffs or staged changes and generates narrative commit messages that explain why a change was made, not just what changed, following Conventional Commits format. Use when asked to “write a commit message,” “describe my changes,” “what should I commit this as,” or “summarize my diff.” Works with git diff output, staged files, or plain descriptions of changes. Does not run git commit; to stage files and make the commit, use the git-commit skill
Designs relational and document database schemas from requirements or an existing app, including tables and collections, keys, relationships, constraints, indexes driven by real query patterns, ERDs, and reversible migration scripts. PostgreSQL (including Supabase) is the default; MySQL, SQLite, and MongoDB are also supported. Use when the user wants to model data for a new app or feature, review or fix an existing schema, choose keys or indexes, plan multi-tenancy, normalize or denormalize, or write CREATE TABLE statements or migrations—even if they just describe their app and ask “how should I store this”. For moving data between database providers, use database-migrator.
Create, read, and manage calendar events and reminders using EventKit and EventKitUI. Use when adding events to the user's calendar, creating reminders, setting recurrence rules, requesting calendar or reminders access, presenting event editors, choosing calendars, handling alarms, observing calendar changes, or working with EKEventStore, EKEvent, EKReminder, EKCalendar, EKRecurrenceRule, EKEventEditViewController, EKCalendarChooser, or EventKitUI views.
Orchestrate agile development workflows for Gitea repositories using the tea CLI. Use when working with Gitea-hosted repos and asking to 'run the workflow', 'continue working', 'what's next', 'complete the task cycle', 'start my day', 'end the sprint', 'implement the next task', or wanting guided step-by-step development assistance. Keywords: workflow, orchestrate, agile, task cycle, sprint, daily, implement, review, PR, standup, retrospective, gitea, tea.
Expert patterns for game economies, including currency management (multi-currency, wallet systems), shop systems (buy/sell prices, stock limits), dynamic pricing (supply/demand), loot tables (weighted drops, rarity tiers), and economic balance (inflation control, currency sinks). Use for RPGs, trading games, or resource management systems. Trigger keywords: EconomyManager, currency, shop_item, loot_table, dynamic_pricing, buy_sell_spread, currency_sink, inflation, item_rarity
jscodeshift codemod development best practices from Facebook/Meta. This skill should be used when writing, reviewing, or debugging jscodeshift codemods. Triggers on tasks involving AST transformation, code migration, automated refactoring, or codemod development
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.
