Ask clarifying questions and get approval before implementation.

Generates ArgoCD Application manifests following the App-of-Apps pattern.

Master C++ for systems programming, game development, and performance-critical applications.

Big tech ML engineer to indie founder transition coach. Expert in idea validation, MVP development, marketing, monetization, and sustainable growth for ADHD entrepreneurs. Activate on 'entrepreneur', 'indie founder', 'startup', 'MVP', 'monetization', 'big tech to indie', 'ADHD business', 'app launch', 'side project'. NOT for neurotypical entrepreneurship, VC-backed startups, or traditional business consulting without ADHD context.

Builds and manages iOS/macOS apps using xcodebuild and xcrun simctl CLI tools. Use when working with Xcode projects, running apps in simulators, managing simulator instances, taking screenshots, capturing logs, running tests, or automating builds.

Advanced prompt engineering techniques for optimal AI responses. Use this when crafting prompts, optimizing AI interactions, or designing system prompts for applications.

Converts approved design documents into agent-executable XML subtasks. Use after a design doc is approved and ready for implementation.

Service workers, offline-first, app manifest, and native-like web experiences.

Process multimedia files with FFmpeg (video/audio encoding, conversion, streaming, filtering, hardware acceleration) and ImageMagick (image manipulation, format conversion, batch processing, effects, composition). Use when converting media formats, encoding videos with specific codecs (H.264, H.265, VP9), resizing/cropping images, extracting audio from video, applying filters and effects, optimizing file sizes, creating streaming manifests (HLS/DASH), generating thumbnails, batch processing images, creating composite images, or implementing media processing pipelines. Supports 100+ formats, hardware acceleration (NVENC, QSV), and complex filtergraphs.

Generates section list for a page. Deterministic mapping. Does not write content.

Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization

This skill generates comprehensive chapter content for intelligent textbooks after the book-chapter-generator skill has created the chapter structure. Use this skill when a chapter index.md file exists with title, summary, and concept list, and detailed educational content needs to be generated at the appropriate reading level with rich non-text elements including diagrams, infographics, and MicroSims. (project, gitignored)

Master xUnit testing patterns for ABP Framework applications including unit tests, integration tests, test data seeders, and mocking strategies. Use when: (1) writing xUnit tests for ABP services, (2) creating test data seeders, (3) implementing integration tests, (4) setting up test infrastructure.

Find and fix performance bottlenecks in ANY language or framework. Use when applications are slow, memory usage is high, or you need to optimize critical paths.

Follow project-wide development conventions including project structure, documentation standards, version control practices, environment configuration, and dependency management. Use this skill when organizing files and directories, writing README documentation, creating commit messages, managing environment variables, updating dependencies, or establishing code review processes. Apply this skill when ensuring consistent project structure (src/, components/, utils/, tests/), maintaining up-to-date documentation, using clear commit messages and feature branches, properly configuring environment variables without committing secrets, keeping dependencies minimal and documented, and implementing feature flags for incomplete work. This skill ensures the entire team follows predictable patterns for project organization, maintains comprehensive documentation for setup and architecture, practices good version control hygiene, manages configuration securely, and establishes clear workflows for testing and code review.

Deployment strategies for Go applications. Use when deploying applications.

Diagnose and fix maturin build issues for PyO3 Python bindings. Use when encountering problems with maturin develop, missing Python exports, module registration errors, or type stub generation issues. Particularly useful when new PyO3 methods compile but don't appear in Python.

Configure Karabiner-Elements keyboard remapping using Goku EDN syntax. Use when creating keybindings, layers, simlayers, app-specific shortcuts, or modifying karabiner.edn.

Generate actionable insights from transaction data. Use when implementing insight generators, anomaly detection, or data analysis features for financial/tax tracking applications.

Perform OSINT, subdomain enumeration, port scanning, web reconnaissance, email harvesting, and cloud asset discovery for initial access. Use when gathering intelligence or mapping attack surface.
