Decide whether and how a game can be ported to PS Vita before writing any port code - the prerequisite check (complete C/C++ source, a working PC build, a supported engine; universal-decompiler repos get first-class handling), prior art (existing Vita ports on VitaDB/GitHub, field notes), vita scan (dependencies vs vdpm, graphics API and GL features, input and the original control scheme, resolutions, 64-bit/SIMD, threads, paths, assets and memory), vita tools check, and the intake - the grouped practical questions with a recommendation grounded in the game for each - recorded in PORT_PLAN.md. Use at the start of any Vita port, or when the user asks "can this run on a Vita?", "what would a Vita port need?", "is there already a Vita port of X?".
