Agent Skills: orient

Use when arriving in an unfamiliar codebase, or returning to one after long enough that its shape has been forgotten. Concerns building a working model of what the system is and where its decisions live, before touching anything. Trigger at the start of work in a new repository, or when a change is about to be made somewhere not yet understood. Do NOT use for a codebase already held in mind, or for answering one specific question — that is research.
