Master ES6+ features including async/await, destructuring, spread operators, arrow functions, promises, modules, iterators, generators, and functional programming patterns for writing clean, efficient JavaScript code. Use when refactoring legacy code, implementing modern patterns, or optimizing JavaScript applications.
add-api
Add new C# APIs to SkiaSharp by wrapping Skia C++ functionality. Structured 6-phase workflow: C++ analysis → C API creation → submodule commits → binding generation → C# wrapper → testing. Triggers: - Issue classified as "New API" (after fetching and classification) - Direct request: "add DrawFoo method", "expose SkSurface::draw", "wrap sk_foo_bar" - Keywords: "add API", "expose function", "wrap method", "create binding for"
session-investigator
Investigate fast-agent session and history files to diagnose issues. Use when a session ended unexpectedly, when debugging tool loops, when correlating sub-agent traces with main sessions, or when analyzing conversation flow and timing. Covers session.json metadata, history JSON format, message structure, tool call/result correlation, and common failure patterns.
ios-debugger-agent
Use XcodeBuildMCP to build, run, launch, and debug the current iOS project on a booted simulator. Trigger when asked to run an iOS app, interact with the simulator UI, inspect on-screen state, capture logs/console output, or diagnose runtime behavior using XcodeBuildMCP tools.
fumadocs-mdx-structure
Create MDX documentation files with proper frontmatter, imports, and component integration. Apply when creating or updating Fumadocs documentation pages in content/docs/.
posthog-migration-deep-dive
Execute PostHog major re-architecture and migration strategies with strangler fig pattern. Use when migrating to or from PostHog, performing major version upgrades, or re-platforming existing integrations to PostHog. Trigger with phrases like "migrate posthog", "posthog migration", "switch to posthog", "posthog replatform", "posthog upgrade major".
llvm-optimization
Expertise in LLVM optimization passes, performance tuning, and code transformation techniques. Use this skill when implementing custom optimizations, analyzing pass behavior, improving generated code quality, or understanding LLVM's optimization pipeline.
caching-strategies
Implement multi-layer caching with Redis, in-memory, and HTTP caching. Covers cache invalidation, stampede prevention, and cache-aside patterns.
test-fixing
Run tests and systematically fix all failing tests using smart error grouping. Use when user asks to fix failing tests, mentions test failures, runs test suite and failures occur, or requests to make tests pass.
