Ephemeral Container Workbench

Use this skill to run one-off tooling in a disposable container while keeping the host clean.

When to use

Trigger for work like:

• installing a converter, SDK, package manager, or system tool that is unlikely to be reused soon
• running a batch operation where inputs and outputs can be bind-mounted
• using a temporary Podman or Docker image to avoid host package changes
• reproducing a command in a clean Linux environment

Do not use when:

• the project already has a committed dev container, toolchain wrapper, or repo-native script that should be used
• the task needs long-lived services, persistent databases, or daemon state
• the operation must integrate deeply with the host desktop, kernel modules, hardware devices, or credentials
• installing the dependency in the repo or user environment is the actual requested outcome
