testland/testcontainers

Brings up real backing services (databases, message brokers, browsers, anything dockerizable) as throwaway containers from inside a test process - Java, Node.js, Python, Go, .NET, Ruby and ten other languages - using the Testcontainers library family. Wires the per-test container lifecycle, exposed-port → host-port mapping, wait strategies (port / log / HTTP / SQL), Ryuk-based cleanup, container-to-container networks, and the (experimental) `withReuse` shortcut for local dev. Use when integration tests need a real Postgres / Redis / Kafka / Selenium / etc. and the team wants per-test isolation without hand-rolled docker-compose teardown.

High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

The skill prompt embeds plaintext database passwords (e.g., POSTGRES_PASSWORD: 'test' and connection URLs like postgres:test) directly into example code and URLs, which requires the LLM to produce verbatim secret values in its output.
