Machine Learning

Use when the user wants to create, edit, list, or manage Claude Code rules in .claude/rules/. Provides guided elicitation to configure path-specific rules with proper YAML frontmatter and glob patterns. Can list all available rules from user-level and project directories.

Define functors from domain to target categories. Uses targets.yaml todetermine which functors to create. Maps domain objects and morphismsto target representations. Use when: mapping domain to API, persistence,events; formalizing structural transformations.

Read C# code files with XML documentation comments stripped to save context. Preserves important comments (TODO, HACK, NOTE). Use when reading code for analysis instead of documentation.

Create and validate YAML diagram files. Use when writing new diagrams or troubleshooting YAML syntax.

This skill should be used when the user asks to "create an esphome config", "set up an esp32 device", "configure esphome yaml", "add a sensor to esphome", "fix esphome compile error", or mentions "gpio pin assignment", "wifi setup", "ota update", or error messages like "Unknown platform", "GPIO already in use", "Could not compile", or "WiFi connection failed". Provides rapid ESPHome configuration generation, troubleshooting, and validation.

Master HTML5 semantic markup and CSS layouts (Flexbox, Grid). Learn responsive design and accessibility best practices for modern web development.

This skill should be used when the user asks to "generate gitlab-ci.yml", "create GitLab CI pipeline", "configure GitLab CI/CD", "use To-Be-Continuous templates", "setup TBC templates", "create CI/CD for Python/Node/Go/Java project", "configure Docker build in GitLab", "setup Kubernetes deployment in GitLab", "add SonarQube to GitLab CI", "configure Terraform with GitLab", or mentions "TBC", "To-Be-Continuous", "Kicker", or needs help selecting CI/CD templates for their project.

Build comprehensive 3-5 year financial models projecting revenue, expenses, headcount, cash flow, and runway. Model unit economics, scenario planning, and path to profitability. Generate investor-ready HTML reports with detailed projections and charts.

Force verification before answering questions involving versions, dates, status, or "current"state. Prevents hallucinations at the REASONING level by checking assertions.yaml and WebSearchbefore forming beliefs. Triggers on software versions, release status, dates, and package versions.

Data format specialist covering TOON encoding, JSON/YAML optimization, serialization patterns, and data validation for modern applications

Prevents 12 errors including SQL BEGIN failures.Use when: defining D1 schemas, managing migrations, writing type-safe queries, implementing relations orprepared statements, using batch API for transactions, or troubleshooting D1_ERROR, BEGIN TRANSACTION,foreign keys, migration apply, or schema inference errors.Prevents 12 documented issues: D1 transaction errors (SQL BEGIN not supported), foreign keyconstraint failures during migrations, module import errors with Wrangler, D1 binding not found,migration apply failures, schema TypeScript inference errors, prepared statement caching issues,transaction rollback patterns, TypeScript strict mode errors, drizzle.config.ts not found,remote vs local database confusion, and wrangler.toml vs wrangler.jsonc mixing.Keywords: drizzle orm, drizzle d1, type-safe sql, drizzle schema, drizzle migration

This skill should be used when converting documents between formats (Markdown, DOCX, PDF, HTML, LaTeX, etc.) using pandoc. Use for format conversion, document generation, and preparing markdown for Google Docs or other word processors.

Use SAP-RPT-1-OSS open source tabular foundation model for predictive analytics on SAP business data. Handles classification and regression tasks including customer churn prediction, delivery delay forecasting, payment default risk, demand planning, and financial anomaly detection. Use when asked to predict, forecast, classify, or analyze patterns in SAP tabular data exports (CSV/DataFrame). Runs locally via Hugging Face model.

Analyzes project tech stack and recommends optimal rule configuration. Detects frameworks from package.json, requirements.txt, go.mod, and other config files. Generates custom manifest.yaml profiles for your specific stack.

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.
