The Creator Kit's prompt-ready orientation in one call: what engine modules exist (party for same-screen multiplayer, zone for a real-time server-arbitrated world, commons and presence for persistent/shared state, and the rest — this is the answer to "can this platform build X", not a web search), plus as much of the core API signatures, audio catalog, and exemplar game as fit in one tool result. The response is sized to a safe single-call limit, not to the whole API — for a real kit this routinely omits content: whole declarations dropped are named in an "Omitted for length" note, and a declaration too large to fit whole is trimmed member-wise with only a count of what was cut, not names. Treat both as normal, not an error. Call this once near the start of a round, before scaffolding, rather than repeatedly — its content only changes when engineRef does. Pass engineRef from get_kit so a mid-round registry bump cannot mix kit revisions. Falls back to the registry's current engine when engineRef is omitted, but that risks reading a different kit than the round is pinned to. Prefer this over unpacking the whole kit into context; use the browse tools (list_kit_files / search_kit_files / read_kit_file) for anything this digest omitted, summarized, or named in its omission note.
