Analyzes, validates, converts, and transforms crystal structures and molecules with pymatgen. It covers CIF/POSCAR/XYZ/JSON conversion, symmetry-tolerance sweeps, local phase diagrams from computed entries, VASP and Q-Chem I/O, band structure and DOS parsing, and bounded Materials Project (mp-api) queries. Use when validating a CIF or checking disorder and oxidation states. Use when assigning space groups and testing symprec sensitivity. Use when converting structure files and checking for representation loss. Use when building a convex hull from total energies. Use when querying Materials Project with explicit fields and limits. Not for general molecular dynamics or non-materials cheminformatics.
Design Rust error types and panic policy — Result over unwrap, thiserror for libraries, anyhow for binaries, context that survives the call stack. Use when code calls unwrap or expect outside tests, when designing or refactoring an error enum, when choosing between thiserror and anyhow, or when the user asks how errors should be handled or propagated.
Get room types and rate packages for a specific hotel. Use this skill after search-hotel when the user wants to explore room options, see different rate plans, compare meal plans (breakfast included vs not), check refundability, or pick a specific room before booking. Triggers on phrases like "show me the rooms at hotel X", "what room types are available", "I want a different rate plan", "is breakfast included".
Lodge, triage and progress complaints in ShiftCare through the complaints MCP tools. Use for "log a complaint from Mary's daughter about missed shifts", "is there already a complaint about this?", "what complaints are open for Mary?", "acknowledge CMP-104233", "close CMP-104233 with this outcome". Decides when a related incident record or urgent escalation is needed instead. Not for recording incidents (there is no incident write tool) and not a substitute for emergency or incident-response procedures. Writes data; never without confirmation.
When the user wants to plan or execute SOX 404 control testing, select audit samples, build testing workpapers, or classify control deficiencies. Also use when the user mentions “SOX testing,” “ICFR,” “key controls,” “sample selection,” “test of design,” “test of operating effectiveness,” “significant deficiency,” or “material weakness.”
STC (Simplified Technical Chinese): Write, rewrite, or review natural, concise, accurate Chinese. Use when the user requests Chinese review, concise wording, removal of unnecessary explanations, consistent terminology, or organized task acknowledgments. Applies to all Chinese output when the project enables STC as the default output rule.
Use this skill when working with Telnyx communication APIs for SMS/MMS messaging, voice calls, phone number management, messaging profiles, webhook integration, two-way SMS conversations, bulk sending, message scheduling, or production deployment of telephony features. v2.0 includes official Telnyx documentation, production patterns from Twilio-Aldea (Ed25519 signature validation, provider-agnostic webhooks, idempotency), and TypeScript code examples.
One-on-one tutor skill for solving math problems and generating HTML explanation documents and voiced Manim animation videos. Core workflow: math analysis → HTML visualization → storyboard script → TTS audio → verification update → scaffolding → Manim code → render verification. Triggers: the student pastes an image of a math problem, needs a teaching video, or needs HTML explanation materials
Analyze Taiwan's manufacturing industry structure including semiconductor, electronics, machinery, and petrochemical sectors. Use this skill when the user needs to understand Taiwan's industrial landscape, evaluate manufacturing sector opportunities, assess supply chain positioning, or contextualize Taiwan in global manufacturing — even if they say 'Taiwan manufacturing overview', 'semiconductor supply chain', 'what does Taiwan make', or 'industrial analysis of Taiwan'.
WOLVERINE v6.0.0 — HYPE Patient-Conviction. Six-gate HYPE single-asset thesis preserved, behavior shifts to fewer-stronger entries with multi-day DSL holds (Bison v3.0.1 pattern port). MIN_SCORE 10, max 2 entries/day, 4h same-asset cooldown, Phase 2 ladder widened to T0 lock 0 so a +10% mover can retrace fully without locking — the structural change that lets winners run into BIG trends instead of getting clipped at the first ratchet. Producer adds recent-signals race-window dedup that eliminated ENGINE_FAILURE retry noise on Bison's decision log. Conviction-tiered leverage (3x standard / 5x apex) preserved — HYPE volatility doesn't yet warrant Bison's 7-10x majors-tier sizing.
Replace with a trigger-style description of when this skill should activate. Be specific — this is what the agent uses to decide whether to load the skill. Example: "Sui TypeScript SDK integration. Use when writing, reviewing, or debugging TypeScript code that interacts with Sui RPCs, transactions, or on-chain state."
Core Python library for astronomy and astrophysics workflows that need Astropy APIs, including units/quantities, coordinates, FITS I/O, tables, time systems, WCS, and cosmology. Use when implementing or debugging astronomical data analysis code with Astropy.
Provides real, analyzed design-token references (DESIGN.md files) for 74 well-known brands and products—including Stripe, Linear, Vercel, Notion, Apple, Coinbase, Airbnb, and Figma—covering color palettes, typography hierarchy, component states, spacing and grids, shadows, and breakpoints. Use whenever the user wants a UI to visually match a specific existing brand or product (“make this look like Stripe,” “give it that Linear feel,” “Notion-style dashboard,” “SaaS aesthetic like Vercel”), or asks what brand references are available. Requires a one-time local clone before first use; see setup section.
Query the BCRA (Banco Central de la República Argentina) Central de Deudores API to check the credit status of individuals or companies in Argentina's financial system. Use when the user asks to check someone's debt situation, credit report, financial standing, rejected checks, or credit history using a CUIT/CUIL/CDI number. Also use when the user mentions "central de deudores", "situación crediticia", "deudas BCRA", "cheques rechazados", "historial crediticio", "informe crediticio", or wants to know if a person or company has debts reported in Argentina's financial system.
A real-time tool for querying a Bilibili account's video list. Retrieves the latest videos published by a Bilibili creator using their UID and supports cursor-based pagination to browse more videos. Use when the user wants to view a creator's video list, Bilibili account videos, or creator submissions.
Apply Porter's Value Chain Analysis to identify competitive advantage sources within an organization's activities. Use this skill when the user needs to find where value is created or lost in their operations, analyze cost structure by activity, optimize internal processes, or identify outsourcing candidates — even if they say 'where do we make money' or 'which activities should we keep in-house'.
Goal-oriented binder design campaign planning and health assessment. Use this skill when: (1) Planning a complete binder design campaign, (2) Converting high-level goals into runnable pipelines, (3) Assessing campaign health and pass rates, (4) Diagnosing why designs are failing QC, (5) Estimating time, cost, and expected yields, (6) Selecting between design tools for a specific target. This skill orchestrates the other protein design tools. For individual tool parameters, use the specific tool skills.
Update, upgrade, or migrate an existing CKEditor 5 integration to the latest or a specific version. Use it to bump the editor version, apply the breaking changes between two versions, move off a legacy installation method (predefined builds, webpack source imports, DLL builds, the old CDN), or fix errors that an update or mismatched CKEditor package versions caused. Do not use it to add CKEditor 5 to a new project, to write custom plugins, for downgrades, or for CKEditor 4.
Use this skill when the user wants to do bookkeeping, accounting, or tax reporting for Bitcoin and Lightning. This includes tracking cost basis, generating capital gains reports, viewing balances, and managing journal entries. Applies even if they don't mention "Clams" directly — any request about BTC profit/loss, tax reports, portfolio value, cost basis tracking, or bitcoin accounting should use this skill.
Author, review, or refactor a skill for the SAP Fiori Tools / open-ux-tools ecosystem. Use this skill whenever the user wants to create a new skill, rewrite an existing one, add references, split an oversized SKILL.md, enforce the `sap-fiori-<feature>` naming convention, validate frontmatter, add CAP/RAP samples, declare OData V2 vs V4 requirements, mark a skill as internal (developer-facing) or external (public), or produce a verification checklist — even if the user does not explicitly say "skill". Enforces host-agnostic tooling, canonical fallbacks, explicit scope boundaries, and progressive-disclosure chunking (<500 lines per file).
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.
