Variable experimental_skillConst Experimental

Type Declaration

• • <const P extends AuthoredPurity | undefined = undefined>(
        spec: SkillSpecInput<P, ClaudeCodeToolVocabulary>,
    ): SkillSpec
  • Experimental

    Define a Claude Code skill with the purity floor enforced AT COMPILE TIME against the Claude Code tool catalog. Identical to the core experimental_skill() at runtime; the typed tools constraint is the only difference.

    Carries the same .input / .step helpers as the core builder, and it must: those two stopped being standalone exports when the helper vocabulary moved onto the skill builder, so an author who picked this door would otherwise have no way to reach them. Before the move they came from vigiles/spec — a second import for one skill, which is the asymmetry this closes rather than a cost it introduces.
