liminality

physea/liminality

Liminality turns hard questions into worked, reusable routes. Hand solve() anything non-trivial: it breaks the problem down, grounds each piece against real tools, and returns a scored decision frame or a synthesized answer instead of a one-off guess. Solved routes are saved and re-runnable, so repeat questions come back faster and cheaper. Grade any result with report_outcome and the routes improve from use. Docs and setup: https://physea.ai/mcp
