Setup Project Context

Invoke /context-engineering. It holds the shape this skill builds and the law every file obeys. If it is not installed, stop and tell the user to install it.

This skill runs once, in a repo with no skills/internal/project-context/. The context should have come first, so the code is the only draft left: mine it, and the owner answers only what the code cannot say. Later decisions go through /context-engineering, and /audit-project-context keeps the result honest.

1. Survey

If skills/internal/project-context/ exists, stop. Tell the user the context already exists: /context-engineering <decision> records a change, and /audit-project-context keeps it. This skill does not run twice.
