Use when user mentions Rust, cargo, rustc, clippy, rustfmt, ownership, borrowing, lifetimes, async Rust, or Rust crates.
Create comprehensive Fishbone (Ishikawa/Cause-and-Effect) diagrams for structured root cause brainstorming. Guides teams through problem definition, category selection (6Ms, 8Ps, 4Ss, or custom), cause identification, sub-cause drilling, prioritization via multi-voting, and 5 Whys integration. Generates visual SVG diagrams and professional HTML reports. Use when brainstorming potential causes, conducting root cause analysis, facilitating quality improvement sessions, analyzing defects or failures, structuring team problem-solving, or when user mentions "fishbone", "Ishikawa", "cause and effect diagram", "6Ms", "cause analysis", or "brainstorming causes".
Property-based testing with fast-check (TypeScript/JavaScript) and Hypothesis (Python). Generate test cases automatically, find edge cases, and test mathematical properties. Use when user mentions property-based testing, fast-check, Hypothesis, generating test data, QuickCheck-style testing, or finding edge cases automatically.

Use when working with .liquid files, creating theme sections and blocks, writing GraphQL queries or mutations for Shopify, building Shopify apps with CLI and Polaris, implementing cart operations via Ajax API, optimising Core Web Vitals for Shopify stores, debugging Liquid or API errors, configuring settings_schema.json, accessing Shopify objects (product, collection, cart, customer), using Liquid filters, creating app extensions, working with webhooks, migrating from Scripts to Functions, or building headless storefronts with Hydrogen and React Router 7. Covers API version 2026-01.
Debug Kubernetes pods, nodes, and workloads using kubectl debug. Covers ephemeral containers, pod copying, node debugging, debug profiles, and interactive troubleshooting sessions. Use when user mentions kubectl debug, debugging pods, ephemeral containers, node debugging, or interactive troubleshooting in Kubernetes clusters.
Python testing with pytest, coverage, fixtures, parametrization, and mocking. Covers test organization, conftest.py, markers, async testing, and TDD workflows. Use when user mentions pytest, unit tests, test coverage, fixtures, mocking, or writing Python tests.
Use when working with Protocol Buffer (.proto) files, buf.yaml, buf.gen.yaml, or buf.lock. Covers proto design, buf CLI, gRPC/Connect services, protovalidate constraints, schema evolution, and troubleshooting lint/breaking errors.
Python code quality with ruff linter. Fast linting, rule selection, auto-fixing, and configuration. Use when checking Python code quality, enforcing standards, or finding bugs.
HTTP API testing for TypeScript (Supertest) and Python (httpx, pytest). Covers REST APIs, GraphQL, request/response validation, authentication, and error handling. Use when user mentions API testing, Supertest, httpx, REST testing, endpoint testing, HTTP response validation, or testing API routes.
JSON querying, filtering, and transformation with jq command-line tool. Use when working with JSON data, parsing JSON files, filtering JSON arrays/objects, or transforming JSON structures.
Elite iOS, macOS, watchOS, tvOS, and visionOS development expertise for Swift, SwiftUI, UIKit, Xcode, and the Apple development ecosystem. Automatically activates when working with .swift files, Xcode projects (.xcodeproj, .xcworkspace), SwiftUI interfaces, Apple platform frameworks (UIKit, Core Data, Combine, WidgetKit, App Intents, etc.), app architecture for Apple platforms, or Apple platform development. Not for cross-platform frameworks (React Native, Flutter) or non-Apple platforms.
Design and scaffold the code execution pattern for MCP-based agent systems. Use when building agents that interact with many MCP tools, when intermediate data is too large for model context, when you need loops/conditionals across tool calls, or when PII must stay out of the model context. Based on Anthropic's engineering guidance.
