Use this skill when writing, reviewing, auditing, or deploying Solidity smart contracts. Triggers on Solidity development, smart contract security auditing, DeFi protocol patterns, gas optimization, ERC token standards, reentrancy prevention, flash loan attack mitigation, Foundry/Hardhat testing, and blockchain deployment. Covers Solidity, OpenZeppelin, EVM internals, and common vulnerability patterns.
Use this skill when designing email campaigns, building drip sequences, improving deliverability, or A/B testing email content. Triggers on email campaigns, drip sequences, newsletter, email deliverability, subject lines, email automation, segmentation, open rates, click-through rates, and any task requiring email marketing strategy or execution.
Run a structured 5-day process to prototype, test, and validate product ideas with real users. Use when the user mentions "design sprint", "validate in a week", "rapid prototype", "test with users", or "de-risk before building". Covers mapping, sketching, deciding, prototyping, and testing. For ongoing experimentation, see lean-startup. For customer job analysis, see jobs-to-be-done. Trigger with 'design', 'sprint'.
Fast web browsing and web app testing for AI coding agents via persistent headless Chromium daemon. Browse any URL, read page content, click elements, fill forms, run JavaScript, take screenshots, inspect CSS/DOM, capture console/network logs, and more. Ideal for verifying local dev servers, testing UI changes, and validating web app behavior end-to-end. ~100ms per command after first call. Works with Claude Code, Cursor, Cline, Windsurf, and any agent that can run Bash. No MCP, no Chrome extension — just fast CLI.
Conduct simulated user research with AI personas. Triggers when the user says 'do user research', 'run user research', 'simulate user interviews', or '/user-research'. Three phases: free growth → pain extraction → product collision, with four quality validation checkpoints. Supports single or multi-concept testing.
Analyzes changed files and improves unit test coverage using project-specific testing conventions from .trellis/spec/ unit-test specs. Determines test scope (unit vs integration vs regression), adds or updates tests following existing patterns, and runs validation. Use when code changes need test coverage, after implementing a feature, after fixing a bug, or when test gaps are identified.
factory_boy test data generation specialist. Covers Factory, DjangoModelFactory, SQLAlchemyModelFactory, all field declarations (Faker, LazyAttribute, Sequence, SubFactory, RelatedFactory, post_generation, Trait, Maybe, Dict, List), batch creation, pytest integration, and Celery task testing patterns. USE WHEN: user mentions "factory_boy", "test factory", "DjangoModelFactory", "SQLAlchemyModelFactory", asks about "test data generation", "factory traits", "SubFactory", "factory fixtures". DO NOT USE FOR: pytest internals - use `pytest`; Django setup - use `pytest-django`; Hypothesis property testing - use `pytest` with Hypothesis
A valid skill with version field for testing
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`
End-to-end type safety patterns for API development. Covers Zod-to-OpenAPI, ts-rest, Zodios, and contract testing. Use for ensuring type consistency between backend and frontend. USE WHEN: user mentions "type-safe API", "end-to-end types", "Zod to OpenAPI", "ts-rest", "Zodios", "contract testing", asks about "share types between frontend and backend", "type safety across API", "API contract", "Pact testing" DO NOT USE FOR: tRPC (use `trpc` instead); GraphQL (use `graphql` instead); Simple OpenAPI generation (use `openapi-codegen` instead); Non-TypeScript projects
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.
Runs Fastly Compute WASM applications locally with Viceroy, specifically for Rust and Component Model projects. Use when starting a local Fastly Compute dev server with Viceroy, configuring fastly.toml for local backend overrides and store definitions, running Rust unit tests with cargo-nextest against the Compute runtime, debugging Compute apps locally, adapting core WASM modules to the Component Model, or troubleshooting local Compute testing issues (connection refused, missing backends, store config). For non-Rust Compute work or understanding the Compute API, prefer the fastlike skill instead — its source code is easier to understand as a Fastly Compute API reference.
