action-cable-patterns
Implements real-time features with Action Cable and WebSockets. Use when adding live updates, chat features, notifications, real-time dashboards, or when user mentions Action Cable, WebSockets, channels, or real-time.
app-specific-patterns
GROWI main application (apps/app) specific patterns for Next.js, Jotai, SWR, and testing. Auto-invoked when working in apps/app.
gitload
This skill should be used when the user asks to "download files from GitHub", "fetch a folder from a repo", "grab code from GitHub", "download a GitHub repository", "get files from a GitHub URL", "clone just a folder", or needs to download specific files/folders from GitHub without cloning the entire repo.
drizzle-orm-d1
Build type-safe D1 databases with Drizzle ORM. Includes schema definition, migrations with Drizzle Kit, relations, and D1 batch API patterns. Prevents 18 errors including SQL BEGIN failures, cascade data loss, 100-parameter limits, and foreign key issues. Use when: defining D1 schemas, managing migrations, bulk inserts, or troubleshooting D1_ERROR, BEGIN TRANSACTION, foreign keys, "too many SQL variables".
create-transformer
Use when creating a new walkerOS transformer. Example-driven workflow for validation, enrichment, or redaction transformers.
create-source
Use when creating a new walkerOS source. Example-driven workflow starting with research and input examples before implementation.
token-integration-analyzer
Token integration and implementation analyzer based on Trail of Bits' token integration checklist. Analyzes token implementations for ERC20/ERC721 conformity, checks for 20+ weird token patterns, assesses contract composition and owner privileges, performs on-chain scarcity analysis, and evaluates how protocols handle non-standard tokens. Context-aware for both token implementations and token integrations.
rate-limiter
Generate rate limiting configurations using AI. Use when protecting APIs from abuse.
implementing-jsc-classes-cpp
Implements JavaScript classes in C++ using JavaScriptCore. Use when creating new JS classes with C++ bindings, prototypes, or constructors.
braintrust-tracing
Braintrust tracing for Claude Code - hook architecture, sub-agent correlation, debugging
net-conventions
C# coding standards for the Exceptionless codebase. Naming conventions, async patterns, structured logging, nullable reference types, and formatting rules. Keywords: C# style, naming conventions, _camelCase, PascalCase, async suffix, CancellationToken, nullable annotations, structured logging, ExceptionlessState
billing
Debug, edit, and fix billing endpoints. Covers legacy endpoints (attach/checkout/cancel) and the new v2 4-layer architecture (setup, compute, evaluate, execute). Use when working on billing, subscription, invoicing, or Stripe integration code.
rerender-functional-setstate
Use functional setState updates to prevent stale closures and unnecessary callback recreations. Apply when updating state based on the current state value in React components.
cloudbase-document-database-web-sdk
Use CloudBase document database Web SDK to query, create, update, and delete data. Supports complex queries, pagination, aggregation, and geolocation queries.
jadx
Android APK decompiler that converts DEX bytecode to readable Java source code. Use when you need to decompile APK files, analyze app logic, search for vulnerabilities, find hardcoded credentials, or understand app behavior through readable source code.
ccxt-typescript
CCXT cryptocurrency exchange library for TypeScript and JavaScript developers (Node.js and browser). Covers both REST API (standard) and WebSocket API (real-time). Helps install CCXT, connect to exchanges, fetch market data, place orders, stream live tickers/orderbooks, handle authentication, and manage errors. Use when working with crypto exchanges in TypeScript/JavaScript projects, trading bots, arbitrage systems, or portfolio management tools. Includes both REST and WebSocket examples.
commit-message
Automatically generates, formats, organizes, and improves git commit messages by analyzing your staged changes using AI. Use this skill when you want to create, write, review, or refine commit messages - whether you need to save time, maintain consistent formatting, or better describe your code changes.
skill-generator
Meta-skill for creating new Claude Code skills with configurable execution modes. Supports sequential (fixed order) and autonomous (stateless) phase patterns. Use for skill scaffolding, skill creation, or building new workflows. Triggers on "create skill", "new skill", "skill generator".
simon-html-tools
Build single-file HTML tools following Simon Willison's patterns - self-contained HTML+JS+CSS applications optimized for LLM generation, no build step, CDN dependencies. Use when creating browser-based tools, utilities, or demos that should be (1) Self-contained in one HTML file, (2) Easy to distribute and host statically, (3) Quick to prototype with LLMs, (4) Client-side only with no server requirements. Ideal for data visualization, API explorers, format converters, debugging tools, and interactive demos.
rate-limiting-apis
Implement sophisticated rate limiting with sliding windows, token buckets, and quotas. Use when protecting APIs from excessive requests. Trigger with phrases like "add rate limiting", "limit API requests", or "implement rate limits".
