Function ConvertBudgetToLevel

internal/thinking/convert.go:77–97

ConvertBudgetToLevel converts a budget value to the nearest thinking level. This is a semantic conversion that maps numeric budgets to discrete levels. Uses threshold-based mapping for range conversion. Budget → Level thresholds: - -1 → auto - 0 → none - 1-512 → minimal - 513-10

(budget int)

//   - level: The converted thinking level string
//   - ok: true if budget is valid, false for invalid negatives (< -1)
func ConvertBudgetToLevel(budget int) (string, bool) {
	switch {
	case budget < -1:
		// Invalid negative values
		return "", false
	case budget == -1:
		return string(LevelAuto), true
	case budget == 0:
		return string(LevelNone), true
	case budget <= ThresholdMinimal:
		return string(LevelMinimal), true
	case budget <= ThresholdLow:
		return string(LevelLow), true
	case budget <= ThresholdMedium:
		return string(LevelMedium), true
	case budget <= ThresholdHigh:
		return string(LevelHigh), true
	default:
		return string(LevelXHigh), true

// HasLevel reports whether the given target level exists in the levels slice.
// Matching is case-insensitive with leading/trailing whitespace trimmed.
