C# and .NET testing patterns with xUnit, FluentAssertions, mocking, integration tests, and test organization best practices.
Patterns for using Testcontainers in .NET integration tests to spin up real dependencies like databases and message queues. Use when writing integration tests that require real databases, testing with message brokers like RabbitMQ or Kafka, or isolating test dependencies with Docker containers.
Apex code quality guardrails for Salesforce development. Enforces bulk-safety rules (no SOQL/DML in loops), sharing model requirements, CRUD/FLS security, SOQL injection prevention, PNB test coverage (Positive / Negative / Bulk), and modern Apex idioms. Use this skill when reviewing or generating Apex classes, trigger handlers, batch jobs, or test classes to catch governor limit risks, security gaps, and quality issues before deployment.
Validates SKILL.md files against Claude Code skill best practices. Checks conciseness, description quality, progressive disclosure, workflow structure, and common anti-patterns. Use when reviewing or auditing skills before shipping.
Build or maintain controller-based ASP.NET Core APIs when the project needs controller conventions, advanced model binding, validation extensions, OData, JsonPatch, or existing API patterns.
OpenAI Codex Rust coding patterns distilled from the codex-rs workspace. Use this skill whenever writing, reviewing, or refactoring Rust code — especially for async agents, CLI tools, sandboxing, Ratatui TUIs, JSON-RPC protocols, tokio-based services, or any codebase that needs defensive panic discipline. Trigger even when the user does not explicitly mention Codex, because the patterns generalize to any production Rust workspace. Covers async cancellation, error enum design, process sandboxing, Cargo workspace architecture, wiremock-based fakes, insta snapshot testing, OpenTelemetry tracing, and Ratatui rendering.
TypeScript strict patterns and best practices. Trigger: When writing TypeScript, defining types/interfaces, or using utility types.
Docker expert for containers, Compose, Dockerfiles, and debugging
When the user wants to create, optimize, or audit a comparison table section—an in-page block (HTML table or responsive equivalent) comparing products, methods, or approaches, with optional supporting copy. Also use when the user mentions "comparison table," "compare table," "feature matrix," "vs table," "side-by-side comparison," "competitor comparison," "traditional vs modern," "manual vs automated," "before and after," "old way vs new way," "alternatives comparison block," or "comparison section on landing page or blog." This skill is for a section inside a page, not a full alternatives URL or blog post wireframe—use alternatives-page-generator for page-level layout, keywords, and PPC destination strategy. For full-page structured data rules, use schema-markup. For FAQ blocks paired with the table, use faq-page-generator.
This skill guides the use of Jupyter notebooks for data analysis, exploration, and visualization, particularly with BigQuery. It outlines best practices for notebook execution and validation (supporting both cell-by-cell execution and full notebook generation depending on tool availability), library installation, and structuring notebooks for clarity. It also covers specific rules for data cleaning, plotting, and integrating with BigQuery SQL and machine learning workflows. Relevant when any of the following conditions are true: 1. The user request involves a data analysis, data exploration, data visualization, or data insights task that requires multiple steps, queries, or visualizations to answer. 2. The user explicitly requests a notebook (.ipynb). 3. You are creating, editing, or executing cells in a Jupyter notebook. 4. You need to query BigQuery from within a notebook. DO NOT use the Python BigQuery client library; instead, you MUST use the `%%bqsql` magics explained in this skill.
Audit all Kafka topic configurations against production best practices using the Lenses MCP server. Checks replication factor, retention, partitions, compaction, naming conventions, orphaned topics and missing metadata. Use when user says "audit my topics", "check topic configs", "topic health check" or asks about retention, replication or partition settings. Do NOT use for creating, deleting or modifying topics.
Extract structured data from web pages using browser automation and DOM queries
