Intent: a yield* result is bound to a const before being used.

// ❌ no
function* () {
    return yield* missingIn(yield* readSheet())
}

// ✅ yes
function* () {
    const sheet = yield* readSheet()
    return yield* missingIn(sheet)
}

Trigger: a yield* whose result is used inside a larger expression: argument, operand, member, property, template.

Exemptions and blind spots: a yield* that is the whole value of a statement (yield* x, return yield* x, if (yield* x), for (… of yield* x)), a declaration or an assignment. Also the whole branch of a ternary, or the right operand of &&/||/??, in one of those positions (const a = cached ?? (yield* x)): binding first would run the effect unconditionally. The autofix extracts every nested yield* into consts, innermost first, named after the argument’s last identifier without a verb prefix (readSheet() → sheet); when that name is taken, prefixed by the object it is read from (reader.rows → readerRows), else numbered (sheet2). There is no autofix when moving the effect could change when or how often it runs: branches of a ternary or &&/||/?? inside a larger expression, optional chaining, while/for conditions, statements without braces, another call evaluated before the yield*.

Why: with several yield*s in one expression the order of effects can only be inferred from precedence. One const per effect makes the order the reading order and names the intermediate value.

Options: none

Fix: autofix
