Unknowns Discovery

Derived from "A Field Guide to Fable: Finding Your Unknowns" (Thariq, Anthropic). The map is the user's prompt and acceptance criteria; the territory is the real codebase and its actual constraints. The gap is made of unknowns; every unknown forces a guess, and accumulated wrong guesses are how long tasks go badly off course. Bias: discovery over speed. Trivial tasks (typo-level fixes) skip this skill entirely.

§1 The four kinds of information in any task

1. Known knowns — what the prompt explicitly states.
2. Known unknowns — what the user knows they have not figured out yet.
3. Unknown knowns — standards the user holds but never wrote down because they felt obvious; they recognize them only on seeing output ("no, not like that").
4. Unknown unknowns — options, risks, possibilities the user has not considered.
