Python async/await patterns with asyncio, concurrent.futures, threading, and multiprocessing. Covers async context managers, timeouts, cancellation, common pitfalls (blocking in async, missing await, event loop issues), and choosing between async/threading/multiprocessing. Use when writing async code, debugging async issues, choosing concurrency approaches, or testing async functions.

Systematic approach to reviewing code for quality, security, and maintainability

Use when designing animations for news sites, content platforms, publishing apps, or media consumption experiences

Эксперт по расписаниям проектов. Используй для WBS, Gantt charts, dependency mapping и resource allocation.

Parse large documents that exceed context limits into structured sections with abstracts, metadata, and hierarchies. This skill should be used when encountering documents over the context limit (typically 25k+ tokens) or when a user explicitly requests document parsing. Apply layout-aware hierarchical chunking principles to preserve semantic structure.

Third-party application installation for Bazzite. CoolerControl, DisplayLink, JetBrains Toolbox, OpenRazer, tablet drivers, scrcpy, and more. Use when users need to install hardware-specific or specialized applications.

Validates Customer Feedback Analyzer Excel exports with 7 view sheets, 36 columns, and professional formatting. Use when checking Excel files, verifying export quality, debugging Excel generation issues, before releasing new versions, or when modifying Excel export code. Ensures zero errors in customer-facing deliverables.

Common application development patterns and implementations

GCP services, Cloud Run, App Engine, and multi-cloud deployment strategies.

7-layer Effect-TS architecture for Holochain applications. Use when implementing domains, validating architecture, or creating stores with standardized patterns.

Triggers when reading or writing documents exceeding 20,000 tokens (~80,000 characters or ~15,000 words). Use when encountering large files, lengthy documentation, big markdown documents, massive PRDs, architecture docs, or any content that risks context window overflow. Activates on phrases like "this document is long", "large file", "too many tokens", or when Claude detects document size approaching limits.

Use when adding features, changing behavior, or modifying architecture. Creates change proposal with specs and tasks. ALWAYS ask for approval before proceeding to implementation. Do NOT use for bug fixes or trivial changes.

Context management tools for Claude Code - provides intelligent codebase mapping with Python, Rust, and C++ parsing, duplicate detection, and MCP-powered symbol queries. Use this skill when working with large codebases that need automated indexing and context management.

Comprehensive RSpec testing for Ruby and Rails applications. Covers model specs, request specs, system specs, factories, mocks, and TDD workflow. Automatically triggers on RSpec-related keywords and testing scenarios.

Systematically refactor code based on analysis, applying improvements while maintaining functionality. Use when the user asks to "refactor this code", "improve code quality", "apply improvements", "fix anti-patterns", "optimize performance", or mentions "clean up code", "make it more maintainable", or "reduce complexity". Works best when an implementation_plan.md exists.

Comprehensive software architecture skill for designing scalable, maintainable systems using ReactJS, NextJS, Bun, Express, React Native, Swift, Kotlin, Flutter, Postgres, GraphQL, Go, Python. Includes architecture diagram generation, system design patterns, tech stack decision frameworks, and dependency analysis. Use when designing system architecture, making technical decisions, creating architecture diagrams, evaluating trade-offs, or defining integration patterns.

Use when reviewing commit messages for compliance with the seven rules from cbea.ms/git-commit - checks subject line length, imperative mood, line wrapping, and that the message explains what and why

Screenshot-based regression testing with Playwright. Compares rendered pixels against baseline PNGs. Use when working with stories, *.visual.spec.ts files, or baseline screenshots. Auto-apply when editing files in stories/ or *.visual.spec.ts.

Systematically debug issues using Sherpa's Bug Hunt workflow. Activates when fixing bugs, investigating errors, debugging broken functionality, or handling regressions. Prevents symptom-fixing by enforcing reproduction-first approach.

Comprehensive DuckDB database backup toolkit supporting both file-based (cp) and native (ATTACH+COPY) backup approaches. Use when you need to backup DuckDB databases locally or to remote storage, create daily scheduled backups, verify backup integrity, or manage backup retention policies.
