This skill should be used when the user asks to "create a skill", "build a skill", "write a skill", "improve skill structure", "understand skill creation", or mentions SKILL.md files, skill development, progressive disclosure, XML structure, or bundled resources (scripts, references, assets). Comprehensive guide for creating effective Claude Code skills.
Systematic codebase investigation to extract architectural patterns and implementation details from an existing project, with findings persisted for long-term reuse. Use when the user wants to explore an open-source or existing codebase to understand how it works and inform the development of a new project. Triggers include: "explore this codebase", "investigate this repo", "how does X implement Y", "I want to build X, study how Y does it", "deep dive into this project", "understand how this works".
Senior Kotlin developer. Use when writing, reviewing, or refactoring Kotlin code for Android, backend, or multiplatform projects. Enforces idiomatic Kotlin and modern patterns.
Senior Terraform and Infrastructure as Code engineer. Use when writing, reviewing, or refactoring Terraform configurations. Enforces modular design and production patterns.
Senior Python developer. Use when writing, reviewing, or refactoring Python code. Enforces idiomatic Python, type hints, and modern patterns.
Senior Docker and containerization expert. Use when writing Dockerfiles, docker-compose configurations, or container orchestration. Enforces security, efficiency, and production patterns.
Senior Node.js developer. Use when building, reviewing, or refactoring Node.js applications. Enforces modern Node.js 22+ patterns, native APIs, performance, and production-ready practices.
Complete full-stack development with Next.js 13+, React, Firebase, Tailwind CSS, and payment integration (Stripe, JazzCash, EasyPaisa). Build production-ready e-commerce platforms, SaaS applications, and scalable web applications. Comprehensive coverage of frontend architecture, backend API routes, database design, authentication systems, payment processing, form handling, error management, and optimization. Generate complete project structures, pages, components, API routes, database schemas, security rules, and deployment configurations using TypeScript.
Workflow orchestration for complex coding tasks. Use for ANY non-trivial task (3+ steps or architectural decisions) to enforce planning, subagent strategy, self-improvement, verification, elegance, and autonomous bug fixing. Triggers: multi-step implementation, bug fixes, refactoring, architectural changes, or any task requiring structured execution.
Find orphan functions, dangling imports, and dead code via GitNexus CLI (npx gitnexus@latest). CLI ONLY - NO MCP server exists, never use readMcpResource with gitnexus:// URIs. TRIGGERS - dead code, orphan functions, unused imports, dangling references, unreachable code.
Use this skill when spreadsheet files are the primary input or output. This means the user wants to: open, read, edit, or repair existing .xlsx, .xlsm, .csv, or .tsv files (e.g., add columns, calculate formulas, format, create charts, clean messy data); create new spreadsheets from scratch or from other data sources; or convert between spreadsheet file formats. Trigger this especially when the user references a spreadsheet file by name or path—even casually (such as "the xlsx in my downloads")—and wants to process it or generate content from it. It's also used to clean or reorganize messy tabular data files (rows with incorrect formatting, misaligned headers, garbage data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do not trigger this when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
Style, review, and refactoring standards for Python codebases with strong typing, explicit error handling, and maintainable module boundaries. Use when Python artifacts are created, changed, or reviewed and Python-specific quality rules must be enforced.
