Compared the port against the original pi setup
(vault/π/learn/.pi: quiz.ts, ask-user-question.ts, teach SKILL.md) —
the pi version never produced invalid correctAnswer values. Root cause
of the port's validation failures: the pi options schema's 'Give each
option a stable value; you reference the correct one by that value in
correctAnswer' sentence was dropped in the port. Without it the model
omits values and must copy a long natural-language label verbatim into
correctAnswer — and instead slugifies it ('cultural-diagnosis' for
'A cultural diagnosis') every turn.
Now matched to pi:
- quiz schema: pi's field order (question, details, options,
multiSelect, correctAnswer, explanation) and descriptions — options
carry the stable-value instruction, correctAnswer is phrased as a
value reference ('the value field of the option you intend'), not a
copy-exact-or-fail threat. nodeId (lh-only, graph) stays.
- ask schema: dropped the redundant 'mode' param (pi has none; the dock
already infers from options presence), pi's descriptions.
- quiz tool description: pi's full text (ask contrast, note field,
dontKnow semantics) minus terminal-only details, plus lh's turn
protocol sentence.
- system-prompt: fixed the stale 'exactly two tools' line (plan/research/
demo/visual tools have their own sections).
Not matched, deliberately: tool results stay JSON (pi sends curated
text; formatAnswerMessage exists if we want it later), shuffle param
(lh always shuffles seeded), pi's ask '(Recommended)' label hint.
