Generates comprehensive documentation explaining how a codebase works, including architecture, key components, data flow, and development guidelines. Use when user wants to understand unfamiliar code, create onboarding docs, document architecture, or explain how the system works.
How to create, manage, and transfer tokens on Hedera using the Hiero JavaScript SDK (@hiero-ledger/sdk). Use this skill whenever the user wants to work with fungible tokens, NFTs, token creation, minting, burning, transfers, token association, custom fees (fixed, fractional, royalty), airdrops, KYC/freeze/wipe/pause operations, or any HTS (Hedera Token Service) operation in JavaScript or TypeScript. Also trigger when users mention @hashgraph/sdk token operations, ERC-20/ERC-721 equivalents on Hedera, or tokenization on the Hedera network.
Client-server communication - RemoteEvent, UnreliableRemoteEvent, RemoteFunction, what survives serialization, typed remote modules, server validation and rate limiting, bandwidth (deltas, buffers, batching), synced time, Zap/Blink. Use when adding remotes, syncing state to clients, debugging nil/lost remote arguments, or reducing lag and bandwidth.

Trigger on 'job scheduling', 'job pool', 'jobpool_id', 'submit a job', 'immediate job', 'cron job', 'scheduled function', 'submitJob', 'createCron', 'retry_interval', 'time_of_execution', or errors 'not a job function', 'job_name must contain only alphanumeric'. Replaces deprecated Cron.
Scaffold code with a conformetry generator instead of writing it by hand. Use when adding a module, component, service, application, or package to a workspace that has a conformetry configuration; when deciding whether a generator exists for the shape you are about to create; when a generator run overwrote or misplaced files; or when a conformance run reports a file that a generator should have produced. Covers both the Nx plugin and the conformetry command-line host, whose input contracts differ.
Looks up Fusion Design Guidelines and applies them to any frontend code in the Fusion ecosystem. USE FOR: layout, spacing, component usage, interaction patterns, any UI implementation decision. DO NOT USE FOR: backend changes, CI/CD, skill authoring, data layer logic.
SAP dependency security and MCP executable trust policy with secure upgrades, cooldowns, staged rollout, and supply-chain protection. Use when upgrading deps, configuring security policies, preventing supply chain attacks, pinning SAP MCP servers, or reviewing SAP CAP/UI5/Fiori/HANA/Datasphere/SAC/BTP/ABAP dependency workflows.
Add or change a conformetry generator, and write the template it renders. Use when a needed generator does not exist yet; when editing a conformetry configuration file; when writing or changing files under a template directory; when choosing placeholders or naming-case variants; when a generated file came out with an empty value or an odd path segment; or when a conformetry command refuses to run because the emitted generator plugin is out of date.
Design, write, and validate a structured learning resource with chapters (<topic>-book/01-quickstart.md, 02-….md …) when a single quick-reference guide is not enough, tailoring it to the reader persona. Check the mapping between chapter learning objectives and comprehension checks, ensure concepts are not used before they are introduced, budget reading time per chapter, include exercises that fail when incomplete and pass when answered, and generate a chapter dependency diagram from book.json. Verify these with verify-book.mjs, and check each chapter’s output, diagrams, and HTML with explainer’s verify-doc.mjs. Use when the user asks for a book, tutorial series, course, “learning materials,” “tutorial,” “hands-on,” “compile it into a book,” “in chapters,” “starting with 01-quickstart,” or when an explainer crash course would take over ~20 minutes or needs exercises.
Profile-guided optimisation skill for C/C++ with GCC and Clang. Use when squeezing maximum runtime performance after standard optimisation plateaus, implementing two-stage PGO builds, collecting profile data, or applying BOLT for post-link optimisation. Activates on queries about PGO, profile-guided optimization, fprofile-generate, fprofile-use, instrumented builds, or BOLT.
Run a conformetry conformance check and act on what it reports. Use when a conformetry-validate target fails; when a composite lint run reports conformance differences; when a report names a missing file, a missing declaration, a missing comment, a placeholder it could not infer, an ambiguous instance, or an unmatched instance; when deciding whether to edit an instance or regenerate it; or before claiming generated code is finished. Covers both the Nx plugin and the conformetry command-line host.
Run parallel feature work safely with Git worktrees. Standardizes branch isolation, port allocation, environment sync, and cleanup so each worktree behaves like an independent local app. Optimized for multi-agent workflows where each agent or terminal session owns one worktree. Use when running multiple feature branches simultaneously, isolating experimental work, or coordinating multi-agent development across the same repo.
Build self-contained interactive HTML dashboards with Chart.js, dropdown filters, and professional styling. Use when creating dashboards, building interactive reports, or generating shareable HTML files with charts and filters that work without a server.
Bytecode interpreter and JIT compiler skill for implementing language runtimes in C/C++. Use when designing bytecode dispatch loops (switch, computed goto, threaded code), implementing stack-based or register-based VMs, adding a simple JIT using mmap/mprotect, or understanding performance trade-offs in interpreter design. Activates on queries about bytecode VMs, dispatch loops, computed goto, JIT compilation basics, tracing JITs, or implementing a scripting language runtime.
Add Sparkle auto-update support to a native macOS app. Use this skill whenever the user wants to add auto-updates, implement Sparkle, set up an appcast feed, add "Check for Updates" to their app, or integrate automatic update checking. Also trigger when the user mentions Sparkle, appcast, SUFeedURL, EdDSA signing, or update notifications. This covers the full setup: adding the Sparkle SPM dependency, creating the UpdaterManager singleton, wiring it into the app delegate and UI, configuring Info.plist, and generating the initial appcast.xml.

Use this skill when the user mentions OpenSearch, search apps, index setup, search architecture, semantic search, vector search, hybrid search, BM25, dense vector, sparse vector, agentic search, RAG, embeddings, KNN, PDF ingestion, document processing, or any related search topic. Also use it for log analytics and observability — when the user wants to set up log ingestion, query logs with PPL, analyze error patterns, set up index lifecycle policies, investigate traces, or check stack health. Activate even if the user says log analysis, Fluent Bit, Fluentd, Logstash, syslog, traceId, OpenTelemetry, or log analytics without mentioning OpenSearch.
Set up a Solidity smart contract project with OpenZeppelin Contracts. Use when users need to: (1) create a new Hardhat or Foundry project, (2) install OpenZeppelin Contracts dependencies for Solidity, (3) configure remappings for Foundry, or (4) understand Solidity import conventions for OpenZeppelin.
Polymarket integration for prediction market trading on Polygon. Covers authentication (L1 EIP-712, L2 HMAC-SHA256, builder headers), order placement (GTC/GTD/FOK/FAK, batch, post-only, heartbeat), market data (Gamma API, Data API, orderbook, subgraph), WebSocket streaming (market/user/sports channels), CTF operations (split, merge, redeem, negative risk), bridge (deposits, withdrawals, multi-chain), and gasless relayer transactions. Use when building AI agents, autonomous market makers, prediction market UIs, or any application integrating with Polymarket on Polygon.
How to create topics, submit messages, and subscribe to real-time message streams on Hedera using the Hiero JavaScript SDK (@hiero-ledger/sdk). Use this skill whenever the user wants to work with Hedera Consensus Service (HCS), including topic creation, message submission, pub/sub messaging, mirror node subscriptions, chunked large messages, topic fees, or any consensus-related operation in JavaScript or TypeScript. Also trigger when users mention @hashgraph/sdk topic operations, event logging on Hedera, decentralized messaging, audit trails, or ordered message streams.
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.
