Expert SOX IT General Controls (ITGC) advisor for finance, internal audit and IT compliance teams. Covers the four ITGC domains external auditors test for SOX 404 — access to programs and data, program changes, computer operations, and program development — plus scoping in-scope systems from the financial statements, designing risk-and-control matrices (RCMs), writing control narratives and test scripts, evaluating deficiencies (control deficiency vs significant deficiency vs material weakness under AS 2201 and Reg S-X), drafting remediation plans, SOX 404(a)/404(b) applicability and filer status, IPO readiness timelines, and COSO 2013 alignment. Use this skill whenever a user mentions SOX, ITGC, IT general controls, 404(a)/404(b), ICFR, material weakness, user access reviews, segregation of duties in IT, change management controls for financial systems, SOX testing or walkthroughs, PCAOB audits, or quarterly compliance for financial reporting systems.
Build the pre-migration spec of a website — pages, redirects, 404s, layout variants, the EDS blocks each page needs with reuse verdicts, dynamic features, martech and open decisions — as documented knowledge files for people and a migration agent. Use when someone asks to scope, estimate or plan a migration, wants "which pages use block X / which blocks does page Y need", a redirect or 404 inventory, or the facts behind a migration brief. Not the migration itself (replica, migrate, rollout)
Accelerate LLM inference using speculative decoding, Medusa multiple heads, and lookahead decoding techniques. Use when optimizing inference speed (1.5-3.6× speedup), reducing latency for real-time applications, or deploying models with limited compute. Covers draft models, tree-based attention, Jacobi iteration, parallel token generation, and production deployment strategies.
Master SQL query optimization, indexing strategies, and EXPLAIN analysis to dramatically improve database performance and eliminate slow queries. Use when debugging slow queries, designing database schemas, or optimizing application performance.
Consolidate duplicate files or directories into one canonical home after approval, held as an identity by this machine's filesystem: hardlink, symlink, junction, or bind mount, with bytes, ACLs, owner and mode, named streams, xattrs and kept timestamps preserved. Use when consumers need the same bytes at several paths and textual references cannot serve them, when asked to hardlink, symlink, junction or bind-mount duplicate copies, or to dedupe identical files or trees on disk without breaking their readers.
Generates images with Stable Diffusion models (SD 1.5, SDXL, SD 3.0, Flux) through the HuggingFace Diffusers library, covering text-to-image, image-to-image, inpainting, outpainting, ControlNet conditioning, LoRA adapters, scheduler swapping, and GPU memory optimization. Use when generating images from text prompts, transforming or restyling an existing image, filling masked regions of an image, adding spatial control from edges, poses, or depth maps, loading LoRA style adapters, or fixing out-of-memory and black-image errors in a Diffusers pipeline. Not for API-only generation without a GPU, where DALL-E 3 fits better.
Guided statistical analysis with test selection and reporting. Use when you need help choosing appropriate tests for your data, assumption checking, power analysis, and APA-formatted results. Best for academic research reporting, test selection guidance. For implementing specific models programmatically use statsmodels.
Carry UI designed and built in your design system's Storybook into the production product, all the way to a pull request. Assesses the work region by region, sorts real copy from placeholder content, translates the story's markup and styles into the product's own templates, wires it to the product's data, scripts, forms, and links, and proves in a browser that the product matches the story. Use when the user says "ship this story", "take this Storybook page to production", "port the redesign into the site", "carry this over from Storybook", "storybook to product", or points at a story and a product repo. The reverse of product-to-storybook, which brings product screens into Storybook. Also runs a catch-up that carries later Storybook changes over, one pull request at a time.
Implement Stripe payment processing for robust, PCI-compliant payment flows including checkout, subscriptions, and webhooks. Use when integrating Stripe payments, building subscription systems, or implementing secure checkout flows.
Router and mental model for STRK20, the Starknet privacy pool. Use when choosing an integration route, answering questions about how STRK20 works (notes, nullifiers, viewing keys, channels, actions, proofs, deposit screening), stating what is hidden vs public, handling compliance and auditing questions, or mapping the ecosystem (shadow accounts, formerly private sub-accounts, the EVM Privacy Bridge, starter kit, RFPs, incubator, brand kit). Implementation work fires the sibling skills directly, strk20-wallet-api for private dapps in TS/React, strk20-anonymizer-contracts for Cairo helpers, strk20-privacy-sdk for wallets and key-holding backends.
Set up real-time event streams with async generator subscriptions using .subscription(async function*() { yield }). SSE via httpSubscriptionLink is recommended over WebSocket. Use tracked(id, data) from @trpc/server for reconnection recovery with lastEventId. WebSocket via wsLink and createWSClient from @trpc/client, applyWSSHandler from @trpc/server/adapters/ws. Configure SSE ping with initTRPC.create({ sse: { ping: { enabled, intervalMs } } }). AbortSignal via opts.signal for cleanup. splitLink to route subscriptions.
Write or revise user-facing product and marketing copy with a specific voice, verifiable claims, natural rhythm, and useful actions. Use for interface labels, onboarding, landing pages, help text, and product messaging. Do not use for code comments or neutral technical documentation unless tone editing is requested.

Covers full Gantt implementation including data binding, task scheduling (auto/manual/custom, week/month duration units), columns (serial number column), resources, timeline configuration, WBS, resource view, critical path, baseline tracking, filtering, sorting, editing (taskbar draw for creating unscheduled tasks), and export functionality (Excel/PDF). Advanced features: task calendars with custom working time, hierarchical checkbox selection modes, dependency type restrictions (allowedDependencyTypes), calendar-driven scheduling with holidays and working time exceptions.
Implements Syncfusion Vue Grid component for feature-rich data tables and grids. Use this when working with data display, sorting, filtering, grouping, aggregates, editing, or exporting. This skill covers grid configuration, CRUD operations, virtual scrolling or infinite scrolling, hierarchy grids, state persistence, and advanced data management features for data-intensive applications.

Build features and bug fixes test-first, with tests that protect behavior. Use when about to implement a feature or bug fix that adds or changes behavior users or callers rely on, including requests that do not mention tests or TDD. Not for removing features or code, behavior-preserving refactors, design or UX exploration, prototypes, styling, copy, configuration that leaves relied-on behavior unchanged, or data cleanup.

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.
