Design and review Rails applications using layered architecture principles from "Layered Design for Ruby on Rails Applications". Use when analyzing Rails codebases, reviewing PRs for architecture violations, planning feature implementations, or implementing patterns like authorization, view components, or AI integration. Triggers on "layered design", "architecture layers", "abstraction", "specification test", "layer violation", "extract service", "fat controller", "god object".
Design and implement visual regression testing for UI changes. Defines screenshot coverage, rendering stabilization, baseline management, and CI integration (e.g., Playwright screenshots, Percy/Chromatic). Use when UI/styling/layout changes need protection against regressions, or when adding screenshot-based tests to a web/WASM/desktop UI.
Use when running tests to validate implementations, collecting test evidence, or debugging failures. Load in TEST state. Covers unit tests (pytest/jest), API tests (curl), browser tests (Claude-in-Chrome), database verification. All results are code-verified, not LLM-judged.
explore — Deep codebase exploration with parallel agents. Use when exploring a repo or discovering architecture.
Primary tool for all code navigation and reading in supported languages (Rust, Python, TypeScript, JavaScript, Go). Use instead of Read, Grep, and Glob for finding symbols, reading function implementations, tracing callers, discovering tests, and understanding execution paths. Provides tree-sitter-backed indexing that returns exact source code — full function bodies, call sites with line numbers, test locations — without loading entire files into context. Use for: finding functions by name or pattern, reading specific implementations, answering 'what calls X', 'where does this error come from', 'how does X work', tracing from entrypoint to outcome, and any codebase exploration. Use Read only for config files, markdown, and unsupported languages.

Create organized, visual study notes with folder structures, diagrams, and example-based learning from source materials (PDFs, lecture notes, documentation). Use when creating structured learning materials, exam preparation notes, or educational documentation. Triggers - organize study notes, create visual learning materials, generate notes with diagrams, exam prep notes, example-based learning.
Obsidian Knowledge Base Organization Workflow. Trigger scenarios: When users mention "organize Obsidian", "clean up folders", "messy knowledge base", "too many directories", "merge categories". Applicable to: Personal knowledge management, note organization, folder restructuring.
Project analysis tool designed to analyze the system architecture and inter-module data flow of codebases. This skill applies when you need to understand project structure, generate architecture diagrams, analyze data flow between modules, or create sequence diagrams. It supports outputting visual charts using Mermaid syntax. Use cases: (1) Project architecture organization (2) Module dependency analysis (3) Data flow tracing (4) New team member project onboarding (5) Technical document generation
Feishu Message Sending and Document Creation Workflow. Trigger Scenarios: When users mention "send Feishu message", "Feishu document", "notify someone", "send to Feishu", "Feishu notification". Applicable to: Sending Feishu messages, creating Feishu documents, operating Feishu Base, managing Knowledge Base.
