testcontainers-python specialist. Covers all container modules (PostgreSQL, MySQL, MongoDB, Redis, Kafka, RabbitMQ, MinIO, Elasticsearch, LocalStack), GenericContainer, wait strategies, Docker Compose, networks, pytest fixtures, and CI/CD integration. USE WHEN: user mentions "testcontainers", "docker in tests", "real database in tests", "test with real postgres/redis/kafka", asks about container fixtures or Docker-based testing. DO NOT USE FOR: Spring Boot testcontainers (Java) - use `spring-boot-integration`; Mocking HTTP - use `fastapi-testing`; Pure pytest patterns - use `pytest`
Emulated Google OAuth 2.0 and OpenID Connect for local development and testing. Use when the user needs to test Google sign-in locally, emulate OIDC discovery, handle Google token exchange, configure Google OAuth clients, or work with Google userinfo without hitting real Google APIs. Triggers include "Google OAuth", "emulate Google", "mock Google login", "test Google sign-in", "OIDC emulator", "Google OIDC", "local Google auth", or any task requiring a local Google OAuth/OIDC provider.
Extract text from images using OCR. Use when the user shares a screenshot and you need to read the text content, copy UI labels, or extract copy from a design mockup.
C# and .NET testing patterns with xUnit, FluentAssertions, mocking, integration tests, and test organization best practices.
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.
[Pragmatic DDD Architecture] Guide for creating tests. Use when creating unit tests, integration tests, or understanding test conventions. Covers our tightly coupled stack: Vitest (unit, integration, ui projects), file naming, transactional database integration tests (txTest) with testcontainers/node-postgres/drizzle, mock patterns (createMock*RepoWithAssertions), and neverthrow Result assertions.
Generate standardized enterprise product prototypes from business requirements, prototype references, `.pen` files, HTML mockups, or design files. Defaults to Element Plus-style admin UI, supports query/add/edit/delete state pages, right-drawer workflows, full-page overlays, true table structures, pagination, business logic notes, and page-state consistency validation. Use when building or normalizing backend management prototypes with Pencil MCP.
Build high-quality visual Web artifacts using HTML/CSS/JavaScript/React — web pages, landing pages, dashboards, interactive prototypes, HTML slide decks, animated demos, UI mockups, data visualizations, and more. Use this skill whenever the user's request involves a visual, interactive, or front-end deliverable, including: - Creating web pages, landing pages, dashboards, marketing pages - Building interactive prototypes or UI mockups (with device frames) - Building HTML slide decks / presentations - Creating CSS/JS animations or timeline-driven animated demos - Turning design mockups, screenshots, or PRDs into interactive implementations - Data visualization (Chart.js / D3, etc.) - Design system / UI Kit exploration Even if the user doesn't explicitly say "HTML" or "web page," this skill applies whenever the intent is to produce something visual, interactive, or presentational. Not applicable: pure back-end logic, CLI tools, data-processing scripts, non-visual code tasks, command-line debugging.
This skill should be used when generating and editing images using the Gemini API (Nano Banana Pro). It applies when creating images from text prompts, editing existing images, applying style transfers, generating logos with text, creating stickers, product mockups, or any image generation/manipulation task. Supports text-to-image, image editing, multi-turn refinement, and composition from multiple reference images.
Always use when user asks to create, generate, draw, or design a diagram, flowchart, architecture diagram, ER diagram, sequence diagram, class diagram, network diagram, mockup, wireframe, or UI sketch, or mentions draw.io, drawio, .drawio files, diagram export to PNG/SVG/PDF, or requests editing/updating an existing diagram.
Generate on-brand marketing images via Codex's built-in image_generation tool. Trigger when user asks to: (a) create marketing assets (ad / logo / slide / product-mockup / scene / lighting-transform / LinkedIn-or-social carousel) for a specific brand, (b) extract or build a brand profile (DESIGN.md) from URL / Tailwind config / tokens.json / Figma Variables / CSS custom props / description / existing brand asset, (c) maintain on-brand consistency across multiple image jobs for the same brand. Do NOT trigger for: UI code generation, frontend reference imagery (use imagegen-frontend-web instead), video generation, or general image editing without brand context.
Guides agents through the first frontend implementation pass from a Google Stitch prototype bundle. Use when the user asks to initialize a frontend project from tech-stack.md, convert design.md/prd.md and Stitch HTML/image prototypes into consistent pages, create mock-data-backed screens with reserved backend API calls, and coordinate every phase with $eliteforge-task-progress-tracker and user confirmations.
