Machine Learning

Extracts 'version' or 'uuid' fields from YAML frontmatter using uv.

從規格目錄的 acceptance.yaml 生成/維護 BDD/ezSpec 測試。使用類似 Gherkin 語法，AI 自動產生 step definition（開發人員不需要手寫），驗收測試規格即為 Executable Specification。

Universal methodology for discovering and adapting to any codebase's patterns, conventions, and architectural decisions. Automatically detects technology stack, learns project structure, and identifies coding standards. Use when encountering unfamiliar code, unknown frameworks, need to understand project patterns. Triggers: 'architecture', 'structure', 'conventions', 'tech stack', 'patterns', 'how is organized', '구조', '아키텍처', '패턴', '컨벤션', '기술스택', '어떻게 구성', '분석', analyzing package.json, go.mod, flake.nix, Cargo.toml, .gitignore files.

Ensures every UI component looks modern and professional with clean, minimal design. Use when building ANY user interface element including buttons, forms, cards, layouts, web pages, or React/HTML artifacts. Provides spacing, typography, color, and interaction guidelines.

Generate minimal HTML pages to review Claude Code output in a browser. Use when terminal output is hard to read, when reviewing lists/tables/drafts, or when user says "show me", "make this reviewable", "quick view", or "open as webpage". Produces unstyled semantic HTML only. For granular feedback with inline comments, see the comment-mode skill.

Machine learning pipeline development with scikit-learn. Use this skill for training models, cross-validation, hyperparameter tuning, and model evaluation.

Package entire code repositories into single AI-friendly files using Repomix. Capabilities include pack codebases with customizable include/exclude patterns, generate multiple output formats (XML, Markdown, plain text), preserve file structure and context, optimize for AI consumption with token counting, filter by file types and directories, add custom headers and summaries. Use when packaging codebases for AI analysis, creating repository snapshots for LLM context, analyzing third-party libraries, preparing for security audits, generating documentation context, or evaluating unfamiliar codebases. | Sử dụng khi: đóng gói repo, pack codebase, context cho AI.

Create Technical Specifications (SPEC) - Layer 10 artifact using YAML format for implementation-ready specifications

Generate and edit draw.io diagrams in XML format with proper font settings, arrow placement, and Japanese text support. Use when creating flowcharts, architecture diagrams, sequence diagrams, or any visual diagrams in .drawio format. Handles font family settings, arrow layering, text sizing, and PNG export validation.

Detects, validates, and migrates codex configuration formats (JSON → YAML). Provides deprecation warnings and migration guidance.

Advanced visual regression testing with pixel-perfect comparison, AI-powered diff analysis, responsive design validation, and cross-browser visual consistency. Use when detecting UI regressions, validating designs, or ensuring visual consistency.

Debug and fix bugs by reproducing issues, identifying root causes, implementing fixes, and validating without regressions. Use when debugging reported bugs, investigating test failures, or resolving production issues requiring root cause analysis.

Use when asked to convert between KML and GeoJSON formats, or convert geo data for mapping applications.

Master statistical analysis with hypothesis testing, A/B testing, regression, and statistical methods for data-driven decisions.

Format citations in APA, MLA, Chicago, IEEE, Harvard styles from structured data, DOI/ISBN lookup, or manual entry. Generate bibliographies with auto-sort.

Contact discovery specialist - handles contact classification, email verification, GDPR compliance, and opportunity enrichment.

Production patterns for integrating Maud HTML templates with Axum 0.8.x web services. Covers IntoResponse implementation, handler patterns, state management with templates, error pages, layouts, and server-side rendering architecture. Use when building Axum HTTP endpoints that return HTML, creating web UIs, or implementing server-side rendered applications.

Recipe collection manager. Extracts recipes from URLs (websites, Instagram, YouTube), images, and Apple Notes. Stores in structured YAML format with family preferences tracking. Supports sync to/from Notion.

Master process modeling with BPMN, flowcharts, swimlane diagrams, and process optimization techniques for business process improvement.

Optimize user onboarding to reduce time-to-value and increase activation rates. Design clear paths to the "aha moment" through checklists, product tours, educational content, and personalized flows. Generate actionable HTML reports with funnel analysis, email sequences, and A/B testing plans.
