Author an Implementable Language Specification

Take an author from a rough language idea to a specification precise enough that a developer with zero access to the author can build a conforming implementation from the document alone. The output is a spec in the mold of the GraphQL specification — grammar, semantics, validation, execution, and conformance — that other devs can implement and interoperate against.

The hard part of a language spec is not prose; it is eliminating the ambiguities the author does not know they are leaving. Two implementers reading a vague sentence produce two incompatible languages. So this skill's method is grilling: ask one sharp question at a time, recommend a default, and refuse to write down any answer that fails the stranger / edge-case / two-implementers tests. It bundles a scaffold script, a completeness linter, and reference docs for the anatomy, the formal notation, and the interview itself.
