Development
Comprehensive expertise for Azure Static Web Apps including architecture, configuration, API integration with Azure Functions, authentication, routing, deployment, and CI/CD. Use when building, configuring, deploying, or troubleshooting Azure Static Web Apps projects with frameworks like React, Angular, Vue, Blazor, or vanilla JavaScript.

Use this skill when integrating BoxLang with Java: createObject, static method calls, type conversion, importing classes, passing closures as functional interfaces, including JARs, JSR-223 scripting, or using Java libraries from BoxLang code.
DeFi legos and protocol composability on Ethereum and L2s. Major protocols per chain — Aerodrome on Base, GMX/Pendle on Arbitrum, Velodrome on Optimism — plus mainnet primitives (Uniswap, Aave, Compound, Curve). How they work, how to build on them, and how to combine them. Use when building DeFi integrations, choosing protocols on a specific L2, designing yield strategies, or composing existing protocols into something new.
Build and deploy applications on inference.sh. Use when getting started, understanding the platform, creating apps, configuring resources, or needing an overview of inference.sh app development. Supports both Python and Node.js. Triggers: inference.sh app, belt app, inf.yml, inference.py, inference.js, deploy app, app development, build app, create app, GPU app, VRAM, app resources, app secrets, app integrations, multi-function app
Covers implementing Cloudflare Turnstile, the invisible CAPTCHA alternative for bot protection: creating widgets and sitekey/secret pairs, embedding the cf-turnstile widget or @marsidev/react-turnstile, server-side token validation through the siteverify API, widget lifecycle and reset handling, pre-clearance for SPAs, custom actions and cData, required CSP directives, and E2E testing with dummy keys. Use when protecting forms, login and signup flows or API endpoints from spam and bots, migrating from reCAPTCHA or hCaptcha, integrating Turnstile with React, Next.js, Hono or Workers, or debugging error 110200 unknown domain, 300030 widget crash, 600010 configuration error, 200500 CSP iframe blocking, token expiry and single-use reuse failures, or Safari 18 Hide IP problems.
Writing, refactoring, or reviewing code for maintainability or design — keeping what you change readable, cohesive, and cheap to change next time. Triggers on "readable", "too long", "refactor", "abstraction", "cohesion", "magic number", "dead code", "what should this be called", or "should this live elsewhere". While authoring, each concern is a practice to uphold; while reviewing, a finding to raise against the diff. Covers cohesion as the test of what belongs in one unit, naming and file organization, abstraction boundaries, complexity limits, dead code, and SOLID/DRY/KISS/YAGNI judgment.
Semantic search, grep, and Q&A across codebases and documentation indexed in CodeAlive. Use when the user mentions "CodeAlive", asks to list or get data sources, list indexed repositories, search code or docs across remote repos, fetch artifact content, or trace call graphs across repositories.
This skill should be used to run an Agent-Ready Codebase Assessment — scoring a codebase across 8 dimensions with parallel agents, producing a weighted score (0-100), band rating, and improvement roadmap. Supports Ruby, Python, PHP, TypeScript, JavaScript, Go, Java, Scala, and Rust.
Use when designing or explaining anything onchain that has to keep working with nobody running it: who calls each function and why they would, where randomness comes from, whether it can be censored or paused, and what it exposes to everyone onchain. Also use when writing the notes or handoff a build ends with, or when explaining to your human how something onchain actually works. Not for scoping which parts go onchain and the launch plan (`/ship`) or the safety of the contract code itself (`/security`).
Connect any tool (Notion, Stripe, ClickFunnels...) to every agent by installing its official CLI, or writing a one-file Python CLI over its API, then a global skill. Use for "connect-tool notion", "connect X", "make a CLI for X", "use my X API key"
Use when an answer depends on a specific external library, framework, SDK, API, CLI, or cloud service and current or version-accurate documentation materially affects correctness. Auto-load on named-technology API questions, version-specific behavior, setup or migration work, generated code against external APIs, or library-specific errors. Auto-loading never authorizes a network lookup. Before any Context7 resolve or documentation fetch, present the exact proposed lookup, version strategy, mode, and final redacted query, then wait for explicit confirmation. Prefer project-local evidence and official documentation when they are more authoritative. Do not use for library-independent concepts, ordinary refactors, or code whose correctness does not depend on external API behavior.
Guide for Convex actions, scheduling, cron jobs, and orchestration patterns. Use when implementing external API calls, background jobs, scheduled tasks, cron jobs, or multi-step workflows. Activates for action implementation, ctx.scheduler usage, crons.ts creation, or long-running workflow tasks.
A topic router for the AI Engineering from Scratch course. Give it a topic, question, or bug you're working on, and it will point you to the exact lesson that teaches it and the next right command. Trigger phrases: “where to learn,” “which lesson covers,” “course navigation,” “I'm stuck on,” “what should I do next,” “teach me MCP,” “teach me Agent Skills,” “where to prepare for Claude certification,” or "where do I learn", "which lesson covers", "course guide", "I'm stuck on", "what should I do next", "teach me MCP", "teach me Agent Skills", "where do I prepare for a Claude certification"
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).
Explain, derive, and debug CSS math for measurement units, calc(), min(), max(), clamp(), custom properties, inheritance, em/rem scaling, percentages, viewport units, and box model formulas. Use when CSS dimensions compute unexpectedly, when mixing units, when building scalable spacing/type systems, or when reviewing box sizing and inherited values.
Review documents, proposals, and plans through the lens of a CTO. Simulates feedback from a technical leader who has built and scaled multiple companies and values platform thinking, mobile-first craft, and iterative execution. Use when you need engineering leadership review: platform strategy, architecture decisions, team structure proposals, or anything that needs a 'will this scale and can we ship fast?' lens.
Build, review, debug, migrate, or plan date-fns v4 date/time code with @date-fns/tz and @date-fns/utc. Use for date-fns, format, parse, parseISO, addDays, differenceIn*, Interval, Duration, date-fns/fp, locales, TZDate, UTCDate, tz(), utc, transpose, in option, Unicode tokens, DST, SSR hydration date bugs, and migrations from date-fns v2/v3 or date-fns-tz.
Explore a codebase to find opportunities for architectural improvement, focusing on making the codebase more testable by deepening shallow modules. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly coupled modules, or make a codebase more AI-navigable.
Create or update a concise, repository-grounded design document with canonical user stories ready for independent review and feature delivery. Use when asked to write a design doc, PRD, implementation plan, feature spec, requirements, or to turn a technical discussion into an implementable design.
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.
