Entry point and navigation for the web novel workshop. Use when the user says “I want to write a novel,” “I don’t know where to start,” “which skill should I use,” “walk me through the process,” or “help me get started”; is unsure what to do on their first visit; or wants one central entry point instead of memorizing commands. Brings 30+ skills together under four entry points (create/continue/improve/submit), guides the process based on the user’s stage, and automatically invokes the relevant skills.
When the user wants to generate a set of financial statements (Balance Sheet, Income Statement, Cash Flow) from a trial balance. Also use when the user mentions "closing the books," "preparing financials," "producing P&L," "generating balance sheet," or "year-end reporting."
Rewrites vague, wordy, or easily misread Chinese technical text into controlled Chinese (one action per sentence, active voice, one meaning per term, fewer nominalizations, no marketing adjectives or boilerplate). For tool descriptions, error messages, instructions between agents, system prompts, status reports, and READMEs. Includes Strict / 中文-顺 modes and a deterministic linter. Triggers: controlled Chinese, disambiguate Chinese, STE100-style Chinese, clarify this text, "make it so another agent can't misread it". Not for creative, marketing, or literary copy.
Use for contract-based (sales-led / enterprise) agreements in Stigg — the contract that is both an entitlement and an invoice. Covers all three ways to start one — provisioning only (entitlement provisioning, attaching custom subscriptions), billing only (negotiated terms, custom pricing, invoicing), or both — plus attaching or detaching subscriptions, amending, archiving, refreshing contract usage, and reading a customer's contracts and invoices. Triggers include "contract", "enterprise deal", "negotiated terms", "order form", "PO number", "provision access", "entitlement provisioning", "billing contract", "set up billing", "attach subscription to contract", "custom plan subscription", "next invoice", "customer invoices", "amendment", "renewal". Skip for catalog modeling (stigg-pricing-modeling), subscriptions with no contract (stigg-subscriptions), credits (stigg-credits), and per-entity budgets (stigg-governance).
Converts a Stitch screen, a local HTML file, or a URL into modular Vite + React components — TypeScript, theme-mapped Tailwind, dark mode via CSS variables, and clean component architecture. Use this for Vite/React apps without App Router. For Next.js 15 App Router, use stitch-nextjs-components instead. Only the Stitch route needs an API key.

Colour, elevation and material for interfaces. Neutral palettes that survive dark and light mode, semantic tokens, borders versus shadows by theme, alpha overlays, contrast that passes, a single accent used sparingly, glass and blur budgets, theme switching without a flash. Use when building a palette, adding dark mode, fixing colours that look "muddy", "cheap", "flat" or "washed out", or when shadows and borders look wrong in one theme.

Covers setup, series types, data binding, legends, indicators, and user interactions.
Implements Syncfusion Flutter Slider controls (SfSlider, SfRangeSlider, SfRangeSelector) for numeric value selection and range inputs. Use when working with single-value sliders, range selection, or chart-range controllers in Flutter apps. This skill covers thumb and tooltip customization, ticks, dividers, RTL support, drag modes, and chart integrations.
Guide for implementing Syncfusion WinUI DataGrid (SfDataGrid) for tabular data display in desktop applications. Use this skill when working with data grids, sorting, filtering, grouping, or CRUD operations. Covers data binding, column configuration, master-details views, Excel export, and performance optimization including data virtualization and custom templates.
Design or evolve a production system from repository evidence, measurable requirements, capacity math, protected invariants, and explicit trade-offs. Reads an existing codebase as the current architecture, closes the requirements it cannot recover on its own, then draws structurally distinct candidates and recommends one with a chained evidence argument. Produces an interactive HTML report, a structured design.json, and a durable DESIGN.md a later session can resume. In an existing repository it also audits the implementation against the intended architecture and records the debt it finds, each with a remedy and its evidence. Use for repository architecture work, greenfield systems, scaling and sharding plans, datastore or consistency choices, capacity and cost sizing, recording a decision as an ADR, or auditing a system that has drifted from its design. Answers directly when the numbers already settle the choice instead of manufacturing a document.
Prepare a self-contained task or agreed GitLab task set, apply shared review and scoped release planning, and produce a local Markdown plan with manual glab commands. Use when the user asks to prepare a task, an issue, or an agreed task set for execution or GitLab publication. Russian discovery terms: подготовить задачу, подготовить issue.

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.
